                  Pursuant to Rule 13d-2(a) of Regulation 13D-G of the General
Rules and Regulations under the Exchange Act, Nortel Networks Corporation
("Nortel Networks") hereby amends its statement on Schedule 13D, dated October
17, 2002 (the "Schedule 13D"), relating to the ordinary shares, par value one
third pence per share (the "Ordinary Shares"), of Bookham Technology plc, a
corporation organized under the laws of England and Wales ("Bookham"). Unless
otherwise indicated, all defined terms used herein shall have the same meanings
ascribed to them in the Schedule 13D.

Item 2.           Identity and Background.

                  Schedule I to the Schedule 13D is hereby replaced in its
entirety with Schedule I to this Schedule.

Item 3.           Source and Amount of Funds or Other Consideration.

                  Item 3 is hereby amended and restated in its entirety as
follows:

                  As described in the response to Item 4, pursuant to the
Acquisition Agreement, Nortel Networks agreed to sell certain assets comprising
a part of Nortel Networks' optical components business to Bookham and, in
consideration thereof, among other things, Bookham will issue to Nortel Networks
the securities as to which this Schedule relates.

Item 4.           Purpose of Transaction.

                  Item 4 is hereby amended by inserting the following paragraph
prior to the final paragraph thereof:

                  On November 5, 2002, Bookham advised Nortel Networks that the
condition to closing under the Acquisition Agreement that a majority of the
holders of the outstanding Ordinary Shares shall have approved the Acquisition
Agreement and certain related matters had been satisfied. Because such condition
has been satisfied, Nortel Networks may be deemed to beneficially own at this
time the 61,000,000 Ordinary Shares and any of the 9,000,000 Ordinary Shares
underlying the Warrants to the extent such Warrants could be exercised, each to
be issued at the closing under the Acquisition Agreement (the "Equity
Consideration Securities"). The terms of the Warrants prohibit their exercise to
the extent such exercise would result in Nortel Networks and persons acting in
concert with Nortel Networks to hold 30% or more of the issued and outstanding
Ordinary Shares. Nortel Networks hereby expressly declares, pursuant to Rule
13d-4 under the Exchange Act, that the filing of this Schedule shall not be
construed as an admission that it is, for the purposes of Section 13(d) or
Section 13(g) of the Exchange Act or otherwise, the beneficial owner of such
securities.

Item 5.           Interest in Securities of the Issuer.

                  Paragraphs (a) and (b) of Item 5 are hereby amended and
restated in their entirety as follows:

                  (a) - (b) As described above in Item 4, Nortel Networks may,
as a result of the approval by a majority of the holders of the outstanding
Ordinary Shares of the Acquisition Agreement and certain related matters, be
deemed to beneficially own the Equity Consideration Securities, representing
approximately 29.9% of the outstanding Ordinary Shares.

                  Except as set forth in this Item 5, none of Nortel Networks
or, to the best of Nortel Networks' knowledge, any of the individuals named in
Schedule I hereto beneficially owns any Ordinary Shares of Bookham.






                                   SIGNATURES

                  After reasonable inquiry, and to the best of my knowledge and
belief, I certify that the information set forth in this statement is true,
complete and correct.
