Dear Sir:

The representations made in this letter are based solely on discussions with and
representations from the engagement partner on the audits of the financial
statements of this registrant for the two most recent fiscal years. That
individual is no longer with Arthur Andersen LLP.

We have read paragraphs 2, 3, and 4 of Item 4 included in the Form 8-K dated
June 17, 2002 of MRV Communications, Inc. to be filed with the Securities and
Exchange Commission and are in agreement with the statements contained therein.


Very truly yours,
