I, Muoi Van Tran, the Chief Executive Officer of Optical Communication Products,
Inc., certify that:

1. I have  reviewed  this  annual  report on Form 10-K of Optical  Communication
Products, Inc.;

2.  Based on my  knowledge,  this  annual  report  does not  contain  any untrue
statement of a material fact or omit to state a material fact  necessary to make
the statements made, in light of the  circumstances  under which such statements
were made,  not  misleading  with  respect to the period  covered by this annual
report;

3.  Based  on my  knowledge,  the  financial  statements,  and  other  financial
information  included  in this annual  report,  fairly  present in all  material
respects the financial  condition,  results of operations  and cash flows of the
registrant as of, and for, the periods presented in this annual report;

4.  The  registrant's  other  certifying  officers  and  I are  responsible  for
establishing and maintaining  disclosure  controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

        a.  Designed such  disclosure  controls and  procedures,  or caused such
        disclosure controls and procedures to be designed under our supervision,
        to  ensure  that  material   information  relating  to  the  registrant,
        including its consolidated  subsidiaries,  is made known to us by others
        within  those  entities,  particularly  during  the period in which this
        annual report is being prepared;

        b. Evaluated the effectiveness of the registrant's  disclosure  controls
        and  procedures and presented in this report our  conclusions  about the
        effectiveness of the disclosure  controls and procedures,  as of the end
        of the period covered by this report based on such evaluation; and

        c.  Disclosed  in this  report any change in the  registrant's  internal
        control over financial  reporting that occurred during the  registrant's
        fourth fiscal  quarter that has  materially  affected,  or is reasonably
        likely to materially  affect,  the  registrant's  internal  control over
        financial reporting.

5. The registrant's other certifying officers and I have disclosed, based on our
most recent  evaluation of internal  control over  financial  reporting,  to the
registrant's  auditors  and the audit  committee  of the  registrant's  board of
directors (or persons performing the equivalent functions):

        a. All significant deficiencies and material weaknesses in the design or
        operation  of  internal  control  over  financial  reporting  which  are
        reasonably  likely to  adversely  affect  the  registrant's  ability  to
        record, process, summarize and report financial information; and

        b. Any fraud, whether or not material, that involves management or other
        employees  who  have a  significant  role in the  registrant's  internal
        control over financial reporting.
