                               UNIPHASE

Uniphase Corporation designs, develops, manufactures and markets laser 
subsystems and components and modules for fiber optic telecommunications 
and cable television systems and laser subsystems.

Our principal telecommunications products consist of source lasers, 
modulators, pump lasers and transmitters modules.  These products are 
used in today's advanced fiber optic telecommunications networks to 
provide the initial light signal, to encode the signal and to amplify 
the signal over the long distances over which these networks are 
deployed.  Our laser subsystems are designed for a number of 
applications and are purchased by our customers for inclusion into 
equipment for biotechnology, industrial process control and measurement, 
graphics and printing, and semiconductor inspection equipment and other 
applications.

Our initial products consisted of laser subsystems.  These industrial 
lasers are used as a light source within various types of equipment 
manufactured by our customers.  We entered the telecommunications 
markets in 1995 when we acquired United Technologies Photonics, then a 
wholly owned subsidiary of United Technologies Research Center located 
in Hartford, Connecticut.  Since that acquisition, our strategy has been 
to broaden our offering of telecommunications components and modules 
through further acquisitions and internal growth.  We currently operate 
the following subsidiaries or divisions offering products for the 
telecommunications industry:

                             RECENT EVENTS

Merger With JDS Fitel Inc.

On January 28, 1999, we agreed to merge with JDS FITEL, Inc. (Toronto:  JDS) 
in a  merger of equals. The combined company would have a total market value
of US $6.1 billion based on the January 27, 1999 closing prices of each
company's stock.  After the merger, the combined company will be named    
JDS Uniphase Corporation.  

Under the terms of the agreement, JDS FITEL shareholders resident in  Canada
will  be entitled to receive  0.50855 shares of exchangeable stock of JDS
Uniphase Canada, a wholly  owned subsidiary of Uniphase, or, at their option,
0.50855 shares of  Uniphase, for each JDS FITEL share they hold.  The
exchangeable shares  are the economic and voting equivalent of our common stock
and will be exchangeable for shares  of our common stock on a one-for-one basis
at any time.  The current shareholders of JDS FITEL and our current
stockholders will  each own approximately 50 percent of the combined company
following the  merger.  The structure of the transaction is expected to provide
the  opportunity for a tax-free exchange for Canadian holders of JDS FITEL 
stock.  The completion of the merger is conditioned upon regulatory approvals,
as well as  approvals by our stockholders and JDS FITEL's shareholders.


JDS Uniphase Corporation will be quoted on the Nasdaq National Market  and will
report its financial results in U.S. dollars.  

JDS Uniphase will be led by an integrated executive team from both  companies,
Kevin Kalkhoven from Uniphase will be Co-chairman and Chief  Executive Officer.
Jozef Straus from JDS FITEL will become Co-chairman,  President and Chief
Operating Officer.  Both companies will each  nominate one half of the board.  


                                RISK FACTORS

You Should Be Prepared for Substantial Fluctuations in Our Stock Price

     The Unpredictability of our Quarterly Operating Results Could Cause 
     our Stock Price to be Volatile or Decline.

     We have experienced and expect to continue to experience  significant
     fluctuations in our quarterly results, which has caused and may in the 
     future cause substantial fluctuations in the market price of our
     common stock. All of the concerns we discuss under Risk Factors could
     affect our operating results, including, among others

        -   the timing of the receipt of product orders from a limited number of
            major customers,

        -   the loss of one or more of our major suppliers,

        -   competitive pricing pressures,

        -   the costs associated with the acquisition or disposition of
            businesses,

        -   our ability to design, manufacture and ship technically
            advanced products with satisfactory yields on a timely
            and cost-effective basis,

        -   the announcement and introduction of new products by us, and

        -   expenses associated with any intellectual property litigation.

     In addition to concerns potentially affecting our operating results
     addressed elsewhere under Risk Factors, the following factors may
     also influence our operating results:

        -   our product mix

        -   the relative proportions of our domestic and international sales,

        -   the timing differences between when we incur expenses to increase
            our marketing and sales capabilities and when we realize benefits,
            if any, from such expenditures,


Furthermore, our sales often reflect orders shipped in the same  quarter that
they are received, which could impact our revenue recognition in subsequent
quarters.  Also, customers may cancel or  reschedule shipments, and
production difficulties could delay  shipments. In addition, we sell our
telecommunications equipment  products to Original Equipment Manufacturers
who typically  order in large quantities and therefore the timing of
such sales  may significantly affect our quarterly results. An OEM supplies  
system level network products to telecommunications carriers and others and
incorporates our components in these system level products. The timing of such
OEM sales can be affected by factors beyond our control, such as  demand for
the OEMs' products and manufacturing risks experienced  by OEMs. In this
regard, we have experienced rescheduling of  orders by customers in each of our
markets and may experience  similar rescheduling in the future. As a result of
all of these  factors, our results from operations may vary significantly from 
quarter to quarter. 

In addition to the effect of ongoing operations on quarterly  results,
acquisitions or dispositions of businesses, products or  technologies by us
have resulted in and may in the future  result in reorganization of our
operations, substantial charges or  other expenses which have caused and may in
the future cause  fluctuations in our quarterly operating results and cash
flows.   For example, in the second and fourth quarters of fiscal 1998, we 
incurred charges of $6.6 million and $33.7 million, respectively  for acquired
in-process research and development in connection  with the acquisition of
Uniphase Fiber Components and Uniphase  Netherlands.  In the third quarter of
fiscal 1997, we incurred  charges of $33.3 million for acquired in-process
research and  development in connection with the acquisition of Uniphase Laser 
Enterprise.  In addition, we incurred other charges in connection  with
acquisitions completed in fiscal 1999, 1998 and 1997.  

Finally, our net revenues and operating results in future quarters may be
below the expectations of public market securities analysts and investors.
In such event, the price of our common stock would likely decline,
perhaps substantially.

     Factors Other Than Our Quarterly Results Affect Our Stock Price

The market price of our common stock has been and is likely to continue to be
highly volatile due to causes other than our historical quarterly results,
such as

        -   announcements of technological innovations or new products or
            our competitors,

        -   developments with respect to patents or proprietary rights, 

        -   governmental regulatory action, and 

        -   general market conditions.

In addition, the stock  market has from time to time experienced
significant price and  volume fluctuations that are unrelated to the operating 
performance of particular companies.

We are Subject to Manufacturing Difficulties 

     We May Not Maintain Acceptable Manufacturing Yields or Product
     Reliability 

The manufacture of our products involves highly complex and precise  processes,
requiring production in highly controlled and clean  environments.  Changes in
our manufacturing processes or those of our  suppliers or their inadvertent use
of defective or contaminated  materials could significantly reduce our
manufacturing yields and  product reliability.  Because the majority of our
manufacturing costs  are relatively fixed, manufacturing yields are critical to
our results  of operations.  Certain divisions of Uniphase, including Uniphase
Laser  Enterprise and Uniphase Netherlands, have in the past experienced lower 
than expected production yields, which could delay product shipments and 
impair gross margins.  These divisions or any of our other manufacturing 
facilities may not maintain acceptable yields in the future. To the extent we  
do not achieve acceptable manufacturing yields or experience product shipment
delays, our business, operating results and financial condition would be
materially and adversely affected.

During the fourth quarter of fiscal 1998, we commenced construction of a  new
laser fabrication facility in the Netherlands for Uniphase  Netherlands, which
we acquired in June 1998.  Our Uniphase Netherlands  facility has not achieved
acceptable manufacturing yields since the June  1998 acquisition, and there is
continuing risk attendant to this new  facility and its manufacturing yields
and costs.  Uniphase Netherlands  may not successfully manufacture laser
products in the future at yield or cost levels necessary to meet our
customers' needs, if at  all.  In addition, Uniphase Fiber Components is
establishing a  production facility in Sydney, Australia for fiber Bragg
grating  products.  This facility may not manufacture grating products to 
customers specifications at the cost and yield levels required. To the extent 
we do not achieve acceptable manufacturing yields or experience product
shipment delays, our business, operating results and financial condition
would be materially and adversely affected.

     Our Customers May Not Promptly Qualify Our Manufacturing Lines

Customers will not purchase any products (other than limited numbers of
evaluation units) prior to qualification of the manufacturing line for the
product. Each new manufacturing line must go through varying levels of
qualification with  our customers. This qualification process determines
whether the  manufacturing line achieves the customers' minimum quality,
performance  and reliability standards.  Delays in qualification can  cause a
product to be dropped from a long term supply program and result  in
significant lost revenue opportunity over the term of that program. As noted in
the previous paragraph, we are currently completing new manufacturing
facilities in the Netherlands and Australia. We may experience delays in
obtaining customer qualification of these facilities. If we fail in the timely 
qualification of these or other new  manufacturing lines, our operating results
and customer  relationships would be adversely affected.

We Need to Manage Our Growth

We have historically achieved our growth through a combination of 
acquisitions and internally developed new products. As part of our 
strategy to sustain growth, we expect to continue to pursue acquisitions 
of other companies, technologies and complementary product lines. We 
also expect to continue developing new solid state lasers, components 
and other products for OEM customers and attempt to further penetrate 
the telecommunications and CATV markets through these new products.  
Both strategies include risks.  The success of each acquisition will 
depend upon

        -   our ability to manufacture and sell the products of the businesses
            acquired,

        -   continued demand for these products by our customers,

        -   our ability to integrate the acquired business' operations, 
            products and personnel,

        -   our ability to retain key personnel of the acquired businesses, and

        -   our ability to expand our financial and management controls and 
            reporting systems and procedures.

In March 1997, we acquired Uniphase Laser Enterprise, which  produces our
980-nm pump laser products. In June 1998, we acquired  Uniphase Netherlands. In
the case of both acquisitions, we acquired  businesses that had previously been
engaged primarily in research and  development and that needed to make the
transition from a research  activity to a commercial business with sales and
profit levels that are  consistent with our overall financial goals.  This 
transition has not yet been completed at Uniphase Netherlands, which  continues
to operate at higher expense levels and lower gross margins  than those
required to meet our profitability goals. In addition, in  August 1998, we
acquired certain assets of Chassis, and in  November 1998 acquired Uniphase
Broadband.  In January 1999, we  entered into an agreement to combine with JDS
Fitel Inc.  See "Recent  Developments."  We may not successfully manufacture
and sell our  products or successfully manage our growth, and failure to do so
could  have a material adverse effect on our business, financial condition and 
operating results.

Since 1997, when we acquired Uniphase Laser Enterprise, we have  increased our
marketing, customer support and administrative functions  to support an
increased level of operations primarily from our  telecommunications products. 
We may not be successful in creating this  infrastructure nor may we realize
any increase in the level of our sales  and operations through our new
products.  We commenced operations at  Uniphase Telecommunications in 1996 to
penetrate the CATV markets, and  at Uniphase Network Components in 1998 to
develop and market a line of  complementary optical components for our
telecommunications customers.  In each case, we hired development,
manufacturing and other staff in  anticipation of developing and selling new
products.  Our operations may  not achieve levels sufficient to justify the
increased expense levels  associated with these new businesses.

Our Customers are Concentrated and We Have Few Suppliers

     Customers

Historically, orders from a relatively limited number of OEM customers 
accounted for a substantial portion of our net sales from  telecommunications
products.  We expect that, for the foreseeable  future, sales to a limited
number of customers will continue to account  for a high percentage of our net
sales.  Sales to any single customer  may vary significantly from quarter to
quarter.  If current customers do  not continue to place orders we may not be
able to replace these orders  with new orders from new customers.  In the
telecommunications markets,  our customers evaluate our products and
competitive products for  deployment in large telecommunications systems that
they are installing.   Our failure to be selected by a customer for particular
system projects  can significantly impact our business, operating results and
financial  condition.  Similarly, even if we are selected by our customers, if
our  customers are not selected as the primary supplier for an overall system 
installation, we can be similarly adversely affected.  Such fluctuations  could
have a material adverse effect on our business, operating results  and
financial condition.  

One telecommunications customer, CIENA Corporation, accounted for 
approximately 12% of our net sales for fiscal 1998.  One laser  subsystems
customer, the Applied Biosystems Division of Perkin-Elmer  Corporation,
accounted for approximately 10% and 12% of our net sales  for fiscal 1997 and
1996, respectively.  One additional customer, KLA- Tencor Corporation,
purchased both Laser subsystems and Ultrapointe  systems and accounted for 12%
and 13% of our consolidated net sales in  fiscal 1998 and 1996, respectively. 
The Ultrapointe product line was  sold to KLA-Tencor Corporation in December
1998 and will not be a source  of future sales.  No other customers represented
10% or more of total  sales during fiscal 1998.  The loss or delay of orders
from these or  other OEM customers could have a materially adverse effect on
our  business, financial condition and operating results.


     Suppliers

We currently obtain various components included in the manufacture of  our
products from single or limited source suppliers.  A disruption or  loss of
supplies from these companies or a price increase for these  components would
have a material adverse effect on our results of  operations, product
quality and customer relationships.  We currently  utilize a sole source for
the crystal semiconductor chip sets  incorporated in our solid state microlaser
products and acquire our pump  diodes for use in its solid state laser products
from Opto Power  Corporation and GEC.  We also obtain lithium niobate wafers,
gallium  arsenide wafers, specialized fiber components and certain lasers used
in  its telecommunications products primarily from Crystal Technology, Inc., 
Fujikura, Ltd., Philips Key Modules, and Sumitomo, respectively.  We do  not
have long-term or volume purchase agreements with any of these  suppliers, and
these components may not in the future be available in  the quantities required
by us, if at all.



We May Fail to Compete in Our Highly Competitive Industry

     Our Current Business Operations may be Insufficient to 
     Remain Competitive in Our Industry

The telecommunications and laser subsystems markets in which we  sell our
products are highly competitive.  In each of the markets  we serve, we face
intense competition from established  competitors.  Many of these competitors
have substantially greater  financial, engineering, manufacturing, marketing,
service and  support resources than do we and may have substantially greater 
name recognition, manufacturing expertise and capability and  longer standing
customer relationships than do we.  To remain  competitive, we believe we must
maintain a substantial investment  in research and development, marketing, and
customer service and  support.  We may not compete successfully in the laser or
 telecommunications industries in the future, and we may not have  sufficient
resources to continue to make such investments, or we  may not make the
technological advances necessary to maintain our  competitive position so that
our products will receive market  acceptance.  In addition, technological
changes or development  efforts by our competitors may render our products or
technologies  obsolete or uncompetitive.


      We May Not Successfully Develop and Market Solid State Lasers
      in Response to the Declining Markets for Our Gas Lasers

The market for gas lasers is mature and expected to decline as  customers
replace conventional lasers, including gas lasers, with  solid state lasers.
Gas laser subsystems sales accounted for  26.3%, 37.3% and 52.9% of our net
sales for the fiscal years ended  1998, 1997 and 1996, respectively.  Solid
state lasers are  currently expected to be the primary commercial laser
technology  in the future.  Consequently, we have devoted substantial 
resources to developing and commercializing our solid state laser  products. 
We believe that some companies are further advanced  than us in solid state
laser development and are competing with us  for many of the same
opportunities.  To be competitive in our  laser markets, we believe continued
manufacturing cost reductions  and enhanced performance of our laser products
will be required on  a continuing basis as these markets further mature. 
However, our  solid state laser products may not be competitive with products
of  other companies as to cost or performance in the future.

     We May be Unable to Attract and Retain Key Personnel

Our future depends, in part, on our ability to attract and retain  certain key
personnel.  In particular, our research and  development efforts depend on
hiring and retaining qualified  engineers.  Competition for highly skilled
engineers is extremely  intense, and we are currently experiencing difficulty
in  identifying and hiring certain qualified engineers in many areas  of our
business.  We may not be able to hire and retain such  personnel at
compensation levels consistent with our existing  compensation and salary
structure.  Our future also depends on the  continued contributions of our
executive officers and other key  management and technical personnel, none of
whom currently has an  employment agreement with us and each of whom would be
difficult  to replace.  We do not maintain a key person life insurance policy 
on the Chief Executive Officer.  However, the loss of the services  of one or
more of our executive officers or key personnel or the  inability to continue
to attract qualified personnel could delay  product development cycles or
otherwise have a material adverse  effect on our business, financial condition
and operating results.

Our Participation In International Markets Creates Concerns Not Faced
by Domestic-Focused Companies

     International Sales

International sales are subject to inherent risks, including  

        -   unexpected changes in regulatory requirements,

        -   tariffs and other trade barriers,

        -   political and economic instability in foreign markets,

        -   difficulties in staffing and management,

        -   integration of foreign operations,

        -   longer payment cycles,

        -   greater difficulty in accounts receivable collection,

        -   currency fluctuations, and

        -   potentially adverse tax consequences.

International sales accounted for approximately 38.7%, 30.6% and  25.1% of net
sales in fiscal years 1998, 1997 and 1996,  respectively.  We expect that
international sales will continue to  account for a significant portion of our
net sales.  We may  continue to expand our operations outside of the United
States and  to enter additional international markets, both of which will 
require significant management attention and financial resources.   

Since a significant portion of our foreign sales are denominated  in U.S.
dollars, our products may also become less price  competitive in countries in
which local currencies decline in  value relative to the U.S. dollar.  Our
business and operating  results may also be materially and adversely affected
by lower  sales levels which typically occur during the summer months in 
Europe and certain other overseas markets.  Furthermore, the sales  of many of
our OEM customers depends on international sales and,  consequently, this
further exposes us to the risks associated with  such international sales.



The Year 2000 Problem May Disrupt Ours and Our Customers' and Suppliers'
Businesses

We are aware of the risks associated with the operation of information 
technology and non-information technology systems as  the millennium (year
2000) approaches.  The problem is pervasive and complex, and may affect many
information technology and non-information technology systems.  The  Year 2000
problem results from the rollover of the two digit year value  from "99" to
"00".  Systems that do not properly recognize such date- sensitive information
could generate erroneous data or fail.  In  addition to our own systems we rely
on external systems of our  customers, suppliers, creditors, financial
organizations, utilities  providers and government entities, both domestic and
international  (which we collectively refer to as "Third Parties"). 
Consequently, we  could be affected by disruptions in the operations of Third
Parties with  which we interact.  Furthermore, as customers expend resources to
correct their own systems, they may reduce their purchasing frequency  and
volume of our products.

We are using both internal and external resources to assess

        -   Our state of readiness (including the readiness of 
            Third Parties, with which we interact) concerning the Year 
            2000 problem,

        -   our costs to correct material Year 2000 problems related to 
            our internal information technology and non-information
            technology systems,

        -   the known risks related to any failure to correct any Year 
            2000 problems we identify, and

        -   the contingency plan, if any, that we should adopt should any 
            identified Year 2000 problems not be corrected.

We continue to evaluate the estimated costs associated with the efforts  to
prepare for Year 2000 based on actual experience. While the efforts  will
involve additional costs, we believe, based on available  information, that we
will manage our total Year 2000 transition without  any material adverse effect
on our business operations,  products or financial prospects. The
actual outcomes and results could  be affected by future factors including, but
not limited to,

        -   the continued availability of skilled personnel,

        -   cost control,

        -   the ability to locate and remediate software code problems,

        -   critical suppliers and subcontractors meeting their Year 2000 
            compliance commitments, and

        -   timely actions by customers.


We anticipate that we will remediate all Year 2000 risks and be able to 
conduct normal operations without having to establish a Year 2000 
contingency plan.

We are working with our software system suppliers and believe that  certain of
these systems are currently not Year 2000 compliant. However,  we anticipate
that such systems will be corrected for the Year 2000  problem prior to
December 31, 1999. We are working with those Third  Parties to identify any
Year 2000 problems affecting such Third Parties  that could have a material
adverse affect on our business, financial  condition or results of operations.
However, it would be impracticable  for us to attempt to address all potential
Year 2000 problems of Third  Parties that have been or may in the future be
identified. Specifically,  Year 2000 problems have arisen or may arise
regarding the information technology and non-information technology systems of 
Third Parties having widespread  national and international  interactions with
persons and entities generally (for example, certain information technology and
non-information technology  systems of governmental agencies,  utilities and 
information and financial networks) that, if uncorrected, could have a 
material adverse impact on our business, financial condition or  results of
operations. We are still assessing the effect the Year 2000  problem will have
on our suppliers and, at this time, cannot determine  such impact.

We May Not Have Sufficient Proprietary Rights and We May Fail to
Protect Those We Have

       We May Not Obtain the Intellectual Property Rights We Require


The laser, semiconductor capital equipment, and telecommunications  markets in
which we sell our products experience frequent  litigation regarding patent and
other intellectual property  rights.  Numerous patents in these industries are
held by others,  including academic institutions and our competitors.  In the
past  we have acquired and in the future we may seek to acquire license  rights
to these or other patents or other intellectual property to  the extent
necessary for our business.  Unless we are able to  obtain such licenses on
commercially reasonable terms, patents or  other intellectual property held by
others could inhibit our  development of new products for our markets.  While
in the past  licenses generally have been available to us where third-party 
technology was necessary or useful for the development or  production of our
products, in the future licenses to third-party  technology may not be
available on commercially reasonable terms,  if at all.  Generally, a license,
if granted, includes payments by  us of up-front fees, ongoing royalties or a
combination thereof.   Such royalty or other terms could have a significant
adverse  impact on our operating results.  We are a licensee of a number of 
third party technologies and intellectual property rights and are  required to
pay royalties to these third party licensors on  certain of our
telecommunications products and solid state lasers.   During fiscal 1998, 1997
and 1996, we expensed $2.0 million, $1.4  million and $1.3 million,
respectively, in license and royalty  fees primarily in connection with our gas
laser subsystems.

       Our Products May Infringe the Property Rights of Others

The industry in which we operate experiences periodic claims of  patent
infringement or other intellectual property rights.  In  this regard, third
parties may in the future assert claims against  us concerning our existing
products or with respect to future  products under development by us.  Any
litigation to determine the  validity of any third-party claims could result in
significant  expense to us and divert the efforts of our technical and 
management personnel, whether or not we are successful in such  litigation.  If
we are unsuccessful in any such litigation, we  could be required to expend
significant resources to develop non- infringing technology or to obtain
licenses to the technology  which is the subject of the litigation.  We  may
not be successful  in such development or such licenses may not be  available
to us.   Without such a license, we could be enjoined from future sales of  the
infringing product or products.

       Our Intellectual Property Rights May Not Be Adequately Protected

Our future depends in part upon our intellectual property, including trade
secrets, know-how and continuing technological  innovation.  We currently hold
95 U.S. patents on products or  processes and certain corresponding foreign
patents and have  applications for certain patents currently pending.  The
steps  taken by us to protect our intellectual property may not  adequately
prevent misappropriation or that others will not  develop competitive
technologies or products.  Other companies may  be investigating or developing
other technologies that are similar  to ours.  It is possible that patents may
not be issued from any  application pending or filed by us and, if patents do
issue, the  claims allowed may not be sufficiently broad to deter or prohibit 
others from marketing similar products.  Any patents issued to us  may be
challenged, invalidated or circumvented.  Further, the  rights under our
patents may not provide a competitive advantage  to us.  In addition, the laws
of certain territories in which our  products are or may be developed,
manufactured or sold, including  Asia, Europe or Latin America, may not protect
our products and  intellectual property rights to the same extent as the laws
of the  United States.

We Are Subject to Financial Market Risks

We experience financial market risks, including changes in interest  rates,
foreign currency exchange rates and marketable equity security  prices.  We
utilize derivative financial instruments to mitigate these  risks.  We do not
use derivative financial instruments for speculative  or trading purposes.  The
primary objective of our investment activities  is to preserve principal while
at the same time maximizing yields  without significantly increasing risk.  To
achieve this objective, a  majority of our marketable investments are floating
rate and municipal  bonds, auction instruments and money market instruments
denominated in  U.S. dollars.  We hedge currency risks of investments
denominated in  foreign currencies with forward currency contracts.  Gains and
losses on  these foreign currency investments are generally offset by
corresponding  gains and losses on the related hedging instruments, resulting
in  negligible net exposure to us.  A substantial portion of our revenue, 
expense and capital purchasing activities are transacted in U.S.  dollars. 
However, we do enter into these transactions in other  currencies, primarily
European currencies.  To protect against  reductions in value and the
volatility of future cash flows caused by  changes in foreign exchange rates,
we have established hedging programs.   Currency forward contracts are utilized
in these hedging programs.  Our  hedging programs reduce, but do not always
entirely eliminate the impact  of foreign currency exchange rate movements. 
Actual results on our  financial position may differ materially.

We Cannot Determine the Timing and Amount of Our Future Capital Needs
or Whether Such Capital Would Be Available When Needed

We are devoting substantial resources for new facilities and equipment for the
production of source lasers, fiber-Bragg gratings and modules used in
telecommunications and for the development of new solid state lasers. 
Although we believe existing cash balances, cash flow from operations and
available lines of credit, will be sufficient to meet our capital requirements
at least through the end of fiscal 1999, we may be  required to seek additional
equity or debt financing to compete  effectively in these markets.  We cannot
precisely determine the timing  and amount of such capital requirements and
will depend on several factors, including our acquisitions and the demand for
our products and products under development.  Such additional financing may
not available when needed, or, if available, may not on terms satisfactory to
us.

Our Currently Outstanding Preferred Stock and Our Ability to Issue  
Additional Preferred Stock Could Impair Our Common Stockholders

Our Board of Directors has the authority to issue up to 800,000 shares 
of undesignated preferred stock and to determine the powers, preferences 
and rights and the qualifications, limitations or restrictions granted 
to or imposed upon any wholly unissued shares of undesignated preferred 
stock and to fix the number of shares constituting any series and the 
designation of such series, without the consent of our shareholders.  
The preferred stock could be issued with voting, liquidation, dividend 
and other rights superior to those of the holders of common stock.  The 
issuance of preferred stock under certain circumstances could have the 
effect of delaying, deferring or preventing a change in control of 
us.  On June 11, 1998, the Board of Directors authorized and 
declared a dividend distribution of one right for each outstanding share 
of its common stock, to stockholders of record at the close of business 
on July 6,1998, and authorized the issuance of one right with each share 
of common stock issued (including shares distributed from treasury) by 
us thereafter between the record date and the distribution date.  
Each right entitles the registered holder, subject to the terms of the 
Rights Agreement, to purchase from us one unit, equal to one one-thousandth 
of a share of Series B Preferred Stock, at a purchase price of $270 per unit,
subject to adjustment, for each share of common stock held by the holder.  The
purchase price is payable in cash  or by certified or bank check or money order
payable to our order. The description and terms of the rights are set forth in
a  Rights Agreement between us and American Stock Transfer & Trust  Company, as
Rights Agent, dated as of June 22, 1998, as amended from  time to time.


Certain provisions contained in the rights plan, may have the effect of 
discouraging a third party from making an acquisition proposal for 
us and may thereby inhibit a change in control of us.  For 
example, such provisions may deter tender offers for shares of Common 
Stock which offers may be attractive to the stockholders, or deter 
purchases of large blocks of Common Stock, thereby limiting the 
opportunity for stockholders to receive a premium for their shares of 
Common Stock over the then-prevailing market prices.

Certain Anti-Takeover Provisions Contained in Our Charter and under
Delaware Law Could Impair a Takeover Attempt

We are subject to the provisions of Section 203 of the Delaware 
General Corporation Law prohibiting, under certain circumstances, 
publicly-held Delaware corporations from engaging in business 
combinations with certain stockholders for a specified period of time 
without the approval of the holders of substantially all of its 
outstanding voting stock.  Such provisions could delay or impede the 
removal of incumbent directors and could make more difficult a merger, 
tender offer or proxy contest involving us, even if such events 
could be beneficial, in the short term, to the interests of the 
stockholders.  In addition, such provisions could limit the price that 
certain investors might be willing to pay in the future for shares of 
our Common Stock.  Our Certificate of Incorporation and Bylaws 
contain provisions relating to the limitations of liability and 
indemnification of its directors and officers, dividing our Board of 
Directors into three classes of directors serving three-year terms and 
providing that its stockholders can take action only at a duly called 
annual or special meeting of stockholders.  These provisions also may 
have the effect of deterring hostile takeovers or delaying changes in 
control or management of us.

This Prospectus Contains Certain Forward Looking Statements

Investors should carefully consider the risk factors discussed above in 
evaluating an investment in the common stock offered by this prospectus. 
The statements contained in this prospectus that are not purely 
historical are "forward-looking statements" within the meaning of the 
Private Securities Litigation Reform Act of 1995 and Section 21E of the 
Securities Exchange Act, including, without limitation, statements 
regarding Uniphase's expectations, hopes, beliefs, anticipations, 
commitments, intentions and strategies regarding the future. Actual 
results could differ from those projected in any forward-looking 
statements for the reasons, among others, detailed in the preceding 
"Risk Factors." The fact that some of the risk factors described in this 
prospectus may be the same or similar to those described in our past 
filings means only that those risks are present in multiple periods. We 
believe that many of the risks detailed here are part of doing business 
in the industry in which we compete and will likely be present in all 
periods reported. The fact that certain risks are endemic to the 
industry does not lessen the significance of the risk. We have made 
forward-looking statements as of the date of this prospectus and assume 
no obligation to update them, or to update the reasons why actual 
results could differ from those projected in them.

                            USE OF PROCEEDS

Uniphase will not receive any of the proceeds from the sale of the 
shares offered by the selling stockholders, under this prospectus, but 
has agreed to bear certain expenses of registration of the shares under 
federal and state securities laws. This registration statement is 
intended to satisfy certain of Uniphase's obligations under the 
Broadband merger agreement.


                          SELLING STOCKHOLDERS

The following table provides the names of and the number of shares of common
stock beneficially owned by each selling stockholder, and the  number of shares
of common stock beneficially owned by each selling  stockholder upon completion
of the offering or offerings pursuant to  this prospectus, assuming each
selling stockholder offers and sells all  of its or his/her respective shares. 
Selling stockholders may, however,  offer and sell all, or some or none of
their shares.  The respective  donees, pledgees and transferees or other
successors in interest of the  selling stockholders may also sell the shares
listed below as being held  by the selling stockholders.  No selling
stockholder will beneficially  own one percent or greater of Uniphase's
outstanding common stock upon  the sale of their shares offered hereby.  Each
of the ownership  percentages in the second column of the following table was
calculated  based on the 40,399,101 Uniphase voting shares outstanding as of
April 26,1999.

                            PLAN OF DISTRIBUTION

This prospectus relates to the offer and sale from time to time by the 
holders of up to 729,510 shares of common stock.  The shares were issued 
in connection with the acquisition in November 1998 of Broadband 
Communications Products, Inc. by Uniphase.  The selling shareholders are 
the former shareholders of Broadband.  This prospectus has been prepared 
in connection with registering the shares to allow for sales of shares  by the
selling stockholders to the public.   Uniphase has registered the shares for
sale under this  prospectus, but registration of the shares does not
necessarily mean  that any of these shares will be offered and sold by the
selling stockholders. 


Uniphase will not receive any proceeds from the offering by the selling 
stockholders.  The shares may be sold from time to time to purchasers, as
follows:  

        -  directly by any of the selling stockholders, or donees, pledgees,
           transferees or other successors in interest ("transferees") thereof,
           or

        -  by the selling stockholders, or transferees, through dealers or   
           agents.

        -  Dealers or agents participating in any offering of the shares under
           this prospectus  may  receive compensation in the form of commissions
           from the selling stockholders, or transferees and/or the
           purchasers of shares  for whom they may act as agent. The selling
           stockholders, or transferees, and any dealers or agents that
           participate in the  distribution of shares may be deemed to be
           "underwriters" within the  meaning of the Securities Act and any 
           profit on the sale of shares by  them and any commissions received 
           by any such dealers or agents might be deemed to be underwriting
           commissions under the Securities Act.

At a time a particular offer of shares is made, a prospectus supplement, 
if required, will be distributed that will set forth the name and names 
of any dealers or agents and any commissions and other terms 
constituting compensation from the selling stockholders, or transferees 
thereof, and any other required information.  The shares may be sold 
from time to time at varying prices determined at the time of sale or at 
negotiated prices.

In order to comply with the securities laws of certain states, if  applicable,
the shares may be sold only through registered or licensed  brokers or dealers.
In addition, in certain states, the shares may not  be sold unless they have
been registered or qualified for sale in such  state or an exemption from such
registration or qualification  requirement is available and is complied with.

The shares may also be sold in one or more of the following  transactions: 

        -  block transactions (which may involve crosses) in  which a broker-
           dealer may sell all or a portion of such stock as agent  but may  
           position and resell all or a portion of the block as principal   
           to facilitate the transaction;

        -  purchases by any such broker-dealer  as principal and resale by such
           broker-dealer for its own account  pursuant to a prospectus  
           supplement;

        -  ordinary brokerage transactions  and transactions in which any such
           broker-dealer solicits purchasers;  

        -  sales "at the market" to or through a market maker or into an
           existing trading market, on an exchange or otherwise,
           for such shares; and

        -  sales in other ways not involving market makers or established
           trading markets, including direct sales to purchasers.  In
           effecting  sales, broker-dealers engaged by the selling stockholders 
           may arrange  for other broker-dealers to participate.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

The indemnification and liability of the Uniphase's directors and officers are
governed by Delaware law.

Under Section 145 of the General Corporation Law of the State of 
Delaware, Uniphase has broad powers to indemnify its directors and 
officers against liabilities that may incur in such capacities, 
including liabilities under the Securities Act of 1933, as amended (the 
"Securities Act"). Uniphase's Bylaws also provide for mandatory 
indemnification of its directors and executive officers, and permissive 
indemnification of its employees and agents, to the fullest extent 
permissible under Delaware law.

Uniphase's Certificate of Incorporation provides that the liability of 
its directors for monetary damages shall be eliminated to the fullest 
extent permissible under Delaware law. Pursuant to Delaware law, this 
includes elimination of liability for monetary damages for breach of the 
directors' fiduciary duty of care to Uniphase and its stockholders. 
These provisions do not eliminate the directors' duty of care and, in 
appropriate circumstances, equitable remedies such as injunctive or 
other forms of non-monetary relief will remain available under Delaware 
law. In addition, each director will continue to be subject to liability 
for breach of the director's duty of loyalty to the Company, for acts of 
omissions not in good faith or involving intentional misconduct, for 
knowing violations of law, for any transaction from which the director 
derived an improper personal benefit, and for payment of dividends or 
approval of stock repurchases or redemptions that are unlawful under 
Delaware law. The provision also does not affect a director's 
responsibilities under any other laws, such as the federal securities 
laws or state or federal environmental laws.

Uniphase has entered into agreements with its directors and certain of 
its executive officers that require Uniphase to indemnify such persons 
against expenses, judgments, fines, settlements and other amounts 
actually and reasonably incurred (including expenses of a derivative 
action) in connection with any proceeding, whether actual or threatened, 
to which any such person may be made a party by reason of the fact that 
such person is or was a director or officer of Uniphase or any of its 
affiliated enterprises, provided such person acted in good faith and in 
a manner such person reasonably believed to be in or not opposed to the 
best interests of Uniphase and, with respect to any criminal proceeding, 
had no reasonable cause to believe his or her conduct was unlawful. The 
indemnification agreement also sets forth certain procedures that will 
apply in the event of a claim for indemnification thereunder.

Uniphase has obtained a policy of directors' and officers' liability 
insurance that insures Uniphase's directors and officers against the 
cost of defense, settlement or payment of a judgment under certain 
circumstances.

ITEM 17. UNDERTAKINGS

The undersigned Registrant hereby undertakes:

     (1)     To file, during any period in which offers or sales are 
being made, a post-effective amendment to this registration statement:

          (i)     To include any prospectus required by Section 10(a)(3) 
of the Securities Act of 1933;

          (ii)    To reflect in the prospectus any facts or events 
arising after the effective date of the registration statement (or the 
most recent post-effective amendment thereof) which, individually or in 
the aggregate, represent a fundamental change in the information set 
forth in this registration statement. Notwithstanding the foregoing, any 
increase or decrease in volume of securities offered (if the total 
dollar value of securities offered would not exceed that which was 
registered) any deviation from the low or high and of the estimated 
maximum offering price may be reflected in the form of prospectus filed 
with the Commission pursuant to Rule 424(b) if, in the aggregate changes 
in volume and price represent no more than 20 percent change in the 
maximum aggregate offering price set forth in the "Calculation of 
Registration Fee" table in the effective registration statement; and

          (iii)   To include any material information with respect to 
the plan of distribution not previously disclosed in this registration 
statement or any material change to such information in this 
registration statement; provided, however, that subparagraphs (i) and 
(ii) do not apply if the information required to be included in a post-
effective amendment by those paragraphs is contained in the periodic 
reports filed by the Registrant pursuant to Section 13 or Section 15(d) 
of the Securities Exchange Act of 1934 that are incorporated by 
reference in this registration statement.

     (2)     That, for the purpose of determining any liability under the 
Securities Act of 1933, each such post-effective amendment shall be 
deemed to be a new registration statement relating to the securities 
offered herein, and the offering of such securities at that time shall 
be deemed to be the initial bona fide offering thereof.

     (3)     To remove from registration by means of a post-effective 
amendment any of these securities being registered which remain unsold 
at the termination of the offering.

The undersigned Registrant hereby further undertakes that, for the 
purposes of determining any liability under the Securities Act of 1933, 
each filing of the Registrant's annual reports pursuant to Section 13(a) 
or Section 15(d) of the Securities Exchange Act of 1934 (and, when 
applicable, each filing of an employee benefit plan's annual report 
pursuant to Section 15(d) of the Securities Exchange Act of 1934) that 
is incorporated by reference to this registration statement shall be 
deemed to be a new registration statement relating to the securities 
offered therein, and the offering of such securities at that time shall 
be deemed to be the initial bona fide offering thereof.

The undersigned Registrant hereby further undertakes that:

     (1)     For purposes of determining any liability under the 
Securities Act of 1933, the information omitted from the form of 
prospectus filed as part of this registration statement in reliance 
under Rule 430A and contained in a form of prospectus filed by the 
Registrant pursuant to Rule 424(b)(1) or (4), or 497(h) under the 
Securities Act of 1933 shall be deemed to be part of this registration 
statement as of the time it was declared effective.

     (2)     For the purpose of determining any liability under the 
Securities Act of 1933, each post-effective amendment that contains a 
form of prospectus shall be deemed to be a new registration statement 
relating to the securities offered therein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide 
offering thereof.

Insofar as indemnification for liabilities arising under the Securities 
Act of 1933 may be permitted to directors, officers and controlling 
persons of the Registrant pursuant to the provisions described under 
Item 15 of this registration statement, or otherwise (other than 
insurance), the Registrant has been advised that in the opinion of the 
Securities and Exchange Commission such indemnification is against 
public policy as expressed in such Act and is, therefore, unenforceable. 
In the event that a claim for indemnification against such liabilities 
(other than the payment by the Registrant of expenses incurred or paid 
by a director, officer or controlling person of the Registrant in the 
successful defense of any action suit or proceeding) is asserted by such 
director, officer or controlling person in connection with the 
securities being registered, the Registrant will, unless in the opinion 
of its counsel the matter has been settled by controlling precedent, 
submit to a court of appropriate jurisdiction the question whether such 
indemnification by it is against public policy as expressed in such Act 
and will be governed by the final adjudication of such issue.


                                SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the 
Registrant certifies that it has reasonable grounds to believe that it 
meets all of the requirements for filing on Form S-3 and has duly caused 
this registration statement to be signed on its behalf by the 
undersigned, thereunto duly authorized, in the City of San Jose, State 
of California on April 28, 1999.
