ITEM 1.  BUSINESS

  GENERAL DESCRIPTION OF BUSINESS

  Cable Design Technologies Corporation (the "Company", the "Registrant" or
"CDT") was incorporated on May 18, 1988 under the laws of the State of Delaware
with its principal office located at 661 Andersen Drive, Pittsburgh,
Pennsylvania 15220 (Telephone: 412-937-2300).

  CDT is a designer and manufacturer of specialty electronic data transmission
cables and network structured wiring systems.  CDT products include high
performance copper, fiber optic, and composite cable constructions, connectors
and component assemblies that are used in network, communication, computer
interconnect, wireless, commercial aviation, automotive, automation & process
control, and other applications.

  The Company, as it exists today, was incorporated on May 18, 1988, but was
conceived in 1985 by its current President and Chief Executive Officer, Paul
Olson, together with other members of current management, shortly after
acquiring the West Penn Wire Corporation ("West Penn/CDT").  In 1988, the
Company underwent a recapitalization pursuant to which Golder, Thoma, Cressey
Fund II purchased a controlling interest in the Company.  On July 14, 1988, the
Company acquired all of the outstanding capital stock of Cable Design
Technologies Inc. (formerly Intercole Inc.).

  Acquisitions have been an important part of CDT's strategy.  In March 1986,
the Company acquired Mohawk Wire & Cable Corporation ("Mohawk/CDT") , a cable
manufacturer which had established relationships with companies involved in the
early stages of computer network development.  In December 1988, the Company
purchased Montrose Products Company ("Montrose/CDT"), a specialty electronics
cable company with established relationships with IBM and other major purchasers
of computer interconnect products.  In August 1990, the Company established CDT
International to respond to increasing demand for data transmission cable
products in international markets.  In May 1991, the Company expanded its
international presence by purchasing Anglo-American Cables Ltd. ("Anglo/CDT"), a
European cable distributor.  In March 1993, the Company established Phalo/CDT to
further increase its production capabilities and broaden its product line.  In
May 1994, the Company acquired all the outstanding stock of Nya NEK Kabel AB
("NEK/CDT"), located near Gothenburg, Sweden, to enter the sophisticated
broadcast, CATV and antenna cable markets and to expand network systems cable
manufacturing capacity into Europe.  In June 1995, the Company purchased all of
the operating assets of Manhattan Electric Cable Corporation ("Manhattan/CDT")
based in Rye, New York to enhance sales of specialty electronics cable for
industrial automation and robotic applications.  In August 1995, the Company
purchased Cole-Flex Corporation of West Babylon, New York to combine its
sleeving and tubing capabilities with Manhattan/CDT.  In September 1995, the
Company purchased the operating assets of the Raydex Division of Volex Group,
p.l.c. ("Raydex/CDT")  (United Kingdom) to provide additional international
manufacturing capabilities of specialty and high performance electronic cable
for computer network systems, telecommunication, aerospace, CATV, and industrial
applications. On February 2, 1996, the Company acquired the assets of Northern
Telecom Limited's ("Nortel") communication cable and IBDN network structured
wiring products businesses ("NORDX/CDT") (Canada).  On June 4, 1996, the Company
acquired the stock of Cekan A/S ("Cekan/CDT") (Denmark), a manufacturer of high
performance, telecommunication connectors.  On July 25, 1996, the Company
acquired, in exchange for shares of its common stock, X-Mark Industries ("X-
Mark/CDT") (Washington, 

                                       2

 
PA), a manufacturer of specialized metal enclosures for network systems. On
March 14, 1997 the Company acquired 51% of the outstanding stock of Stronglink,
Pty. Ltd. ("Stronglink/CDT") (Australia), to enhance international distribution
of network and specialty cable in the Australian marketplace. On April 7, 1997,
the Company acquired the assets of Dearborn Wire & Cable, L.P. and its

performance specialty cable for commercial and military aviation applications.
In March 1998, the Company acquired all the outstanding stock of (Orebro/CDT) of
Orebro, Sweden, a manufacturer of custom designed wire and cable for wireless
communication, robotics and other industries.

  Subsequently, on August 3, 1998, the Company acquired 80% of HEW-Kabel Heinz
Eilentropp GmbH & Co. KG and related entities ("HEW-Kabel/CDT") located in
Wipperfurth, Germany, a manufacturer of specialty cable for process control,
robotics, transportation, medical and other specialty applications.


  PRODUCTS

  The Company's products are generally comprised of electronic copper and fiber
optic cable and network structured wiring components which are categorized into
two principal product groups, Network Communication and Specialty Electronics.
The markets served by the Company's products include computer local area
networks ("LANS") and wide area networks ("WANS"), communication, computer
interconnect, wireless, commercial aviation, automotive, automation & process
control, and other applications.

Network Communication Product Group:
- ------------------------------------

Network  -  This product line encompasses the cable and the components,
including connectors, wiring racks and panels, outlets and interconnecting
hardware, to complete the end-to-end network structured wiring system
requirements of LANS and WANS. Additional capital expenditures and acquisitions
over the last three years have greatly increased the Company's capacity in this
product area.  Sales of network products were $270.7 million, $249.3 million and
$189.0 million in fiscal 1998, 1997 and 1996, respectively.   Sales of these
products represented approximately 42%, 48% and 53% of the Company's total sales
for the fiscal years 1998, 1997 and 1996, respectively.

Communication - Through the acquisition of NORDX/CDT in fiscal 1996, the Company
entered the market for outside communication, switchboard and equipment cable.
This product group is primarily manufactured by the Company's NORCOM/CDT
facility in Kingston, Ontario, which is the largest communication cable
operation in Canada.  Sales of communication products were $122.6 million for
fiscal 1998, $98.2 million for fiscal 1997, and $53.1 million for the six month
post-acquisition period in fiscal 1996, and represented approximately 19%, 19%
and 15% of the Company's total sales for fiscal 1998, 1997 and 1996,
respectively.

                                       3

 
Specialty Electronics Product Group:
- ------------------------------------

Automation & Process Control  - The automation & process control product line
encompasses four distinct applications for data and signal transmission cables.
Automation applications include climate control, premise video distribution and
sophisticated security and signal systems involving motion detection, electronic
card and video surveillance technologies.  Process control applications include
remote signaling and electronic monitoring systems.  Sound applications include
voice activation, evacuation and other similar systems.  Safety applications
refer to certain attributes of data transmission cable that improve the safety
and performance of such cable under hazardous conditions, particularly in
buildings for advanced fire alarm and safety systems.  The Company's sales for
this product line were $143.4 million, $106.0 million and $81.2 million in
fiscal 1998, 1997 and 1996, respectively.  These products represented 22%, 21%
and 23% of the Company's total sales in fiscal 1998, 1997 and 1996,
respectively.

Specialty - Specialty products refers to a family of highly engineered wire and
cable products for a variety of specialized applications and niche markets,
including commercial aviation and marine, automotive electronics, broadcast,
wireless component assemblies, CATV, microwave antenna, medical electronics,
electronic testing equipment, robotics, electronically controlled factory
equipment, copiers, home entertainment and appliances. Sales of these products
were $103.8 million, $51.4 million and $26.4 million for fiscal 1998, 1997 and
1996, respectively. Sales of these products represented approximately 16%, 10%
and 7% of the Company's total sales for fiscal July 31, 1998, 1997 and 1996,
respectively.

Non-Cable - Non-cable manufacturing activities unrelated to the Company's core
business include precision tire molds and sheet metal products. These products
represented less than 2% of the Company's total sales in each of the last three
fiscal years.


  RAW MATERIALS

  The principal raw materials used by CDT are copper and insulating compounds.
Raw materials are purchased on a consolidated basis whenever possible to reduce
costs and improve supplier service levels. Copper is purchased from several
domestic suppliers.  Price terms are generally producers' prices at time of
shipment.  The Company does not generally engage in hedging transactions for the
purchase of copper. Currently, world stocks of and capacity for copper are
adequate to meet the Company's requirements.  CDT purchases insulating
compounds, including Teflon/(R)/, from various suppliers.  Other raw materials
used by CDT include LEXAN/(R)/, optical fiber, reels, tapes, textiles, chemicals
and other materials.  Currently, supplies of these other raw materials are
adequate to meet the Company's needs and are expected to remain so for the
foreseeable future.


  CUSTOMERS

  The Company sells its products directly to original equipment manufacturers
(OEMs), regional Bell operating companies, certified system vendors, and
established distributors.  The Company supports over 9,500 customers.  No single
customer accounted for more than 10% of sales in fiscal 1998, 1997 or 1996,
except that sales to business units of Bell Canada Enterprises represented
approximately 11% of fiscal 1997 and 1996 sales.

                                       4

 
  COMPETITION

  The markets served by the Company's products are highly competitive.  Although
some of the Company's competitors are substantially larger and have greater
resources than the Company, management believes that it competes successfully in
its markets due to its experienced management team, large sales force,
established reputation, breadth of product offerings, large number of customer
approved specifications and emphasis on quality.

  The principal competitive factors in all the markets for Network Communication
and Specialty Electronics products are availability, customer support, price and
product features.  The relative importance of each of these factors varies
depending on the specific product category.

  In the market for network structured wiring system products, the Company
competes with a large number of competitors, several of which are significantly
larger than the Company.  The Company competes in the network structured wiring
systems market by adapting to shifting customer demand for new products, and in
the case of NORDX/CDT, by offering complete, end to end certified network
structured wiring systems.  In the markets for communication, switchboard and
equipment cable, price, reputation, production quality and availability are
principal competitive factors.  In the automation & process control market, the
Company competes against a relatively large number of companies, most of which
are smaller in size than the Company.  Product prices, company reputation and
product integrity are principal factors which affect competition in the
automation & process control market.  In the specialty products market,
production quality, engineering capabilities and price are principal competitive
factors.


  BACKLOG

  Backlog orders believed to be firm were $75.3 million at July 31, 1998,
compared to $62.2 million at July 31, 1997.  The Company believes that
substantially all of the backlog is shippable within the next twelve months.
Generally, customers may cancel orders for standard cable products without
penalty upon thirty days notice.


  ENVIRONMENTAL MATTERS

  The Company is subject to numerous federal, state, provincial, local and
foreign laws and regulations relating to the storage, handling, emission and
discharge of materials into the environment, including the United States
Comprehensive Environmental Response, Compensation and Liability Act (CERCLA),
the Clean Water Act, the Clean Air Act, the Emergency Planning and Community
Right-To-Know Act and the Resource Conservation and Recovery Act.  Regulations
of particular significance to the Company include those pertaining to handling
and disposal of solid and hazardous waste, discharge of process wastewater and
storm water and release of hazardous chemicals.  Although the Company believes
it is in substantial compliance with such laws and regulations, the Company may
from time to time not be in full compliance and may be subject to fines or other
penalties for noncompliance.

  The Company does not currently anticipate any material adverse effect on its
business as a result of compliance with federal, state, provincial, local or
foreign environmental laws or regulations.  However, some risk of environmental
liability and other costs is inherent in the nature of the Company's business,
and there can be no assurance that material environmental costs will not arise
in the future.

                                       5

 
  EMPLOYEES

  As of July 31, 1998, the Company had approximately 3,200 full time employees,
of which approximately 1,400 were represented by labor unions.  The Company has
not experienced any material work stoppages at its plants and believes its
current relations with its employees are good, however, there can be no
assurance that conflicts will not arise with unions or other employee groups or
that such conflicts would not have a material adverse effect on the Company's
business.


  FOREIGN OPERATIONS

  For information regarding the Company's foreign and domestic operations and
export sales, see Note 14, "Geographic Segments and Export Sales" as presented
in the Company's Notes to Consolidated Financial Statements.


  RESEARCH AND DEVELOPMENT

  For information concerning expenditures on research and development
activities, see Note 2, "Significant Accounting Policies," as presented in the
Company's Notes to Consolidated Financial Statements.


  RISK FACTORS

  Ability to Successfully Integrate Acquisitions.  Although the Company has been
successful in integrating previous acquisitions, no assurance can be given that
it will continue to be successful in integrating future acquisitions.  The
integration and consolidation of acquired businesses will require substantial
management, financial and other resources and may pose risks with respect to
production, customer service and market share. While the Company believes that
it has sufficient financial and management resources to accomplish such
integration, there can be no assurance in this regard or that the Company will
not experience difficulties with customers, personnel or others. In addition,
although the Company believes that its acquisitions will enhance the competitive
position and business prospects of the Company, there can be no assurance that
such benefits will be realized or that any combination will be successful.

  Technological Obsolescence.  Many of the markets that the Company serves are
characterized by rapid technological change.  The Company believes that its
future success will depend in part upon its ability to enhance existing products
and to develop and manufacture new products that meet or anticipate such
changes.  The failure to successfully introduce new or enhanced products on a
timely and cost-competitive basis could have a material adverse effect on the
Company's business.

  Fiber optic technology represents a potential substitute for copper-based
cable products.  A significant decrease in the cost of fiber optic systems or
increase in the cost of copper-based systems could make fiber optic systems
superior on a price performance basis to copper systems and may have a material
adverse effect on the Company's business.  To date, fiber optic cables have not
significantly

                                       6

 
penetrated the markets served by the Company due to the high relative cost
required to interface electronic and light signals and the high cost of fiber
termination and connection. Although the Company is a fiber optic cable supplier
in niche, specialty markets, there can be no assurance that the Company will
have sufficient production capacity for fiber optic cable products in order to
adapt to a potential significant increase in demand for fiber optic cable
products.

  Wireless technology may represent a threat to both copper and fiber optic-
based network and communication systems by reducing the need for premise wiring.
The Company believes that the limited signal security and the relatively slow
transmission speeds of current wireless systems restrict the use of such systems
in many data communication markets. However, there can be no assurance that
future advances in wireless technology will not have a material adverse effect
on the Company's business.

  Products have recently been introduced by other companies that electronically
expand cable bandwidth. By enhancing cable performance, these products allow
expanded data services without upgrading existing cable. These devices are being
sold primarily to telephone companies to enhance local loop and central office
cable performance, eliminating costly replacement of aerial and/or direct burial
telephone cable. The Company believes that the complexity these systems add to
the maintenance and repair of a communication network limits their
attractiveness to users and consequently limits their effect on the Company's
business. There can be no assurance, however, that potential advances in
electronic cable enhancement will not have a material adverse effect on the
Company's business.

  Price Fluctuations and Availability of Raw Materials.  Copper is the principal
raw material purchased by the Company, and the Company's sales may be affected
by the market price of copper.  The Company does not generally engage in hedging
transactions for copper.

  The Company also purchases compounds, such as Teflon(R), from various
suppliers. From time to time, the supply of such materials has been limited. The
inability of suppliers to supply such raw materials could have a material
adverse effect on the Company's business until a replacement supplier is found
or substitute materials are approved for use. Although the Company has generally
been able to pass on increases in the price of copper and other raw materials to
its customers, there can be no assurance that the company will be able to do so
in the future. Additionally, significant increases in the price of copper or
other raw materials could have a negative effect on demand for the Company's
products. Similarly, significant decreases in the price of copper, or excess
supplies of such other raw materials, over time could have a material adverse
effect on the Company's business.

  Foreign Currency Fluctuations. The Company's operations may be adversely
affected by significant fluctuations in the value of the U.S. dollar against
certain foreign currencies or by the enactment of exchange controls or foreign
governmental or regulatory restrictions on the transfer of funds. The most
significant foreign currencies for the Company, in order of dollar equivalent
net sales, during fiscal 1998 were the Canadian dollar and the British pound.

  Competition. The Company is subject to competition from a substantial number
of international and regional competitors, some of which have greater financial,
engineering, manufacturing and other resources than the Company. The Company's
competitors can be expected to continue to improve the design and performance of
their products and to introduce new products with competitive price and
performance characteristics. Although the Company believes that it has certain
technological and other

                                       7

 
advantages over its competitors, realizing and maintaining such advantages will
require continued investment by the Company in engineering, research and
development, marketing and customer service and support. There can be no
assurance that the Company will have sufficient resources to continue to make
such investments or that the Company will be successful in maintaining such
advantages. See "Business -- Competition."

  Environmental Matters. The Company does not currently anticipate any material
adverse effect on its business as a result of compliance with federal, state,
provincial, local or foreign environmental laws or regulations or cleanup costs.
However, some risk of environmental liability and other costs is inherent in the
nature of the Company's business, and there can be no assurance that material
environmental costs will not arise in the future. Moreover, it is possible that
future developments, such as increasingly strict requirements of air emission
control and other environmental laws and enforcement policies thereunder, could
lead to material costs for environmental compliance and cleanup by the Company.

  Year 2000 Compliance. The Company is in the process of completing a review of
the potential impact of the Year 2000 date processing issue on its information
technology ("IT") systems, non-IT systems, such as equipment and machinery
controlled by microcontrollers with embedded technology, and key suppliers and
customers. The Company has plans to modify or replace non-compliant IT systems
prior to the end of the calendar year 1999. While the Company's review of non-IT
systems and key suppliers and customers has not been completed, the Company has
not become aware of any materially adverse Year 2000 compliance issues relating
to such non-IT systems or key suppliers and customers. If, however, the Company,
its key suppliers and customers or other entities upon which the Company relies
(such as utility providers) fail to make necessary modifications, conversions
and contingency plans on a timely basis, the year 2000 issue could have a
material adverse effect on the Company's business, operations, cash flow and
financial condition.

ITEM 3.  LEGAL PROCEEDINGS

  The Company is a party to various legal proceedings and administrative
actions, all of which are of an ordinary or routine nature incidental to the
operations of the Company. In the opinion of the Company's management, such
proceedings and actions should not, individually or in the aggregate, have a
material adverse effect on the Company's results of operations or financial
condition.

  Superior Modular Products, Inc. has offered NORDX/CDT a non-exclusive license
under a patent it contends applies to certain NORDX/CDT patch panels.  The
matter is under negotiation and, at the present time, the Company does not
believe a resolution would have a material adverse effect on its results of
operations.

  Berk-Tek, Inc. ("Berk-Tek") has offered the Company a non-exclusive license
under a patent it contends applies to certain cables sold by Mohawk/CDT. The 
Company's special patent counsel has provided an opinion that the Company's
products do not infringe any valid claims, and, consequently, the offer has 
been declined. Berk-Tek has filed an application to reissue the patent in 
consideration of relevant prior art which has been identified by the Company
and others, and has re-offered a non-exclusive license. Currently, the 
probability that Berk-Tek's application to reissue the patent with claims of 
interest to the Company will be granted cannot be determined and, therefore, 
based upon the opinion of the Company's special patent counsel, at this time,
the Company does not believe a resolution of this matter would have a material 
adverse effect on its results of operations.

  In December, 1997, the Company and certain of its subsidiaries were named in a
lawsuit filed by the

                                       9

 
Furon Company (Case No. 1:97CF 3292, United States District Court, N.D. Ohio).
In July, 1998, the Company, its subsidiaries and the Furon Company settled such
litigation on mutually satisfactory terms. The settlement will not have a
material adverse effect on the Company.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
                           ON SUPPLEMENTAL SCHEDULE



We have audited in accordance with generally accepted auditing standards, the
consolidated financial statements included in Cable Design Technologies
Corporation and Subsidiaries' annual report to stockholders incorporated by
reference in this Form 10-K, and have issued our report thereon dated September
11, 1998. Our audits were made for the purpose of forming an opinion on those
financial statements taken as a whole. The schedule listed in the accompanying
index is presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audits of
the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.
