          I have reviewed this quarterly report on Form 10-QSB/A of Alliance Fiber Optic
          Products, Inc.;

2.
          Based on my knowledge, this 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 report;

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

4.
          The small business issuers other certifying officer 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 small business issuer 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 small business issuer, including its consolidated
               subsidiaries, is made known to us by others within those entities, particularly
               during the period in which this report is being prepared;
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b)
               Evaluated the effectiveness of the small business issuer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 small business issuers internal control
               over financial reporting that occurred during the small business issuers most recent
               fiscal quarter that has materially affected, or is reasonably likely to
               materially affect, the small business issuers internal control over financial
               reporting; and
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

5.
          The small business issuers other certifying officer and I have disclosed, based on
          our most recent evaluation of internal control over financial reporting, to the
          small business issuers auditors and the audit committee of the small business issuer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 small business issuer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 small business issuers internal control over
               financial reporting.
