As of March 26, 2012, the Opnext Supporting Stockholders beneficially owned an aggregate of 37,756,552 shares of Opnext Common Stock (which number includes, pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), 2,727,235 shares of Opnext Common Stock issuable upon the exercise of stock options that are exercisable within 60 days after March 26, 2012 (the “Option Shares”)), representing approximately 40.5% of the sum of (i) 90,405,097 shares of Opnext Common Stock represented by Opnext in the Merger Agreement (as defined in Item 4 below) to be outstanding as of March 23, 2012 and (ii) the Option Shares.

Oclaro did not pay additional consideration to the Opnext Supporting Stockholders in connection with the execution and delivery of the Opnext Voting Agreements and thus no funds were used for such purpose. For a description of the Opnext Voting Agreements, see Item 4 below, which description is incorporated herein by reference in response to this Item 3.

ITEM 4.

PURPOSE OF TRANSACTION

(a)-(b)

On March 26, 2012, Oclaro entered into an Agreement and Plan of Merger and Reorganization (“Merger Agreement”), by and among Opnext, Tahoe Acquisition Sub, Inc., a newly formed wholly owned subsidiary of Oclaro (“Merger Sub”) and Oclaro, pursuant to which Oclaro and Opnext will combine their businesses through a merger of Merger Sub with and into Opnext (the “Merger”).

Pursuant to the terms of the Merger Agreement, at the effective time of the Merger, by virtue of the Merger and without any action on the part of any stockholder, each share of Opnext Common Stock will be converted into the right to receive 0.42 of a share of common stock of Oclaro (the “Exchange Ratio”), par value $0.01 per share (“Oclaro Common Stock”). Options to purchase Opnext Common Stock will be assumed by Oclaro pursuant to the terms of the Merger Agreement. Stock appreciation rights with respect to Opnext Common Stock and restricted stock units of Opnext will be converted into stock appreciation rights with respect to Oclaro Common Stock and restricted stock units of Oclaro pursuant to the terms described in the Merger Agreement.

Each of Opnext and Oclaro has made customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants: (a) to conduct their respective businesses in the ordinary course, consistent with past practice, during the interim period between the execution of the Merger Agreement and the consummation of the Merger; (b) not to engage in certain kinds of transactions during such period; (c) to convene and hold meetings of the stockholders of each of Opnext and Oclaro to approve the transaction; and (d) that, subject to certain exceptions, the Boards of Directors of Opnext and Oclaro will each recommend that their respective stockholders approve the transaction.

Consummation of the Merger is subject to customary conditions, including: (a) the adoption of the Merger Agreement by the stockholders of Opnext and the approval by the stockholders of Oclaro of the issuance of shares of Oclaro Common Stock and of a Certificate of Amendment to Oclaro’s Certificate of Incorporation in connection with the Merger; (b) expiration of the waiting period under U.S. antitrust laws; (c) absence of any applicable restraining order or injunction prohibiting the Merger; (d) the effectiveness of a registration statement on Form S-4; (e) the absence of material adverse effect with respect to each of Opnext and Oclaro; (f) the accuracy of the representations and warranties of each party, subject to specified materiality thresholds; (g) performance in all material respects by each party of its obligations under the Merger Agreement; and (h) the delivery of customary tax opinions from counsel to Opnext and Oclaro. The Merger Agreement contains certain termination rights for both Opnext and Oclaro in certain circumstances, some of which would require Opnext or Oclaro to pay the other a termination fee of $6,000,000.

At the same time that the Merger Agreement was entered into, the Opnext Supporting Stockholders entered into Voting Agreements (the “Opnext Voting Agreements”) with Oclaro, and each of the directors and certain executive officers of Oclaro (the “Oclaro Supporting Stockholders”) entered into Voting Agreements (the “Oclaro Voting Agreements”) with Opnext.

The Opnext Voting Agreements provide that each Opnext Supporting Stockholder will vote his/her Opnext Common Stock in favor of the adoption of the Merger Agreement and against any alternative transaction with respect to Opnext. The Opnext Voting Agreements will terminate upon the date of the earliest of: (a) the termination of the Merger Agreement in accordance with its terms; (b) the effectiveness of the Merger; (c) the change in recommendation by the Board of Directors of Opnext pursuant to Section 5.2(c)(i) of the Merger Agreement in the context of a superior offer for Opnext; or (d) an amendment of the Merger Agreement decreasing the Exchange Ratio or otherwise materially and adversely affecting the applicable Opnext Supporting Stockholder.

The Oclaro Voting Agreements provide that each of the Oclaro Supporting Stockholders will vote his/her Oclaro Common Stock in favor of the issuance of Oclaro Common Stock pursuant to the Merger Agreement, in favor of the Certificate of Amendment of Oclaro’s Certificate of Incorporation and against any alternative transaction with respect to Oclaro. The Oclaro Voting Agreements will terminate upon the date of the earliest of: (a) the termination of the Merger Agreement in accordance with its terms; (b) the effectiveness of the Merger; (c) the change in recommendation by the Board of Directors of Oclaro pursuant to Section 5.3(c)(i) of the Merger Agreement in the context of a superior offer for Oclaro; or (d) an amendment of the Merger Agreement increasing the Exchange Ratio or otherwise materially and adversely affecting the applicable Oclaro Supporting Stockholder.

The foregoing summary descriptions of the Merger Agreement, the Opnext Voting Agreements and the Oclaro Voting Agreements do not purport to be complete and are qualified in their entirety by reference to the full text of the Merger Agreement, the form of the Opnext Voting Agreements and the form of the Oclaro Voting Agreements, copies of which are attached as exhibits hereto or incorporated herein by reference.

(c)	Not applicable.

(d)

Upon consummation of the Merger, the directors and officers of Merger Sub immediately prior thereto will become the directors and officers, respectively, of Opnext as the surviving corporation in the Merger. The existing director of Merger Sub is Jerry Turin, and the existing officers of Merger Sub are Jerry Turin, President, Chief Financial Officer and Treasurer; and Kate Rundle, Secretary.

(e)

Under the terms of the Merger Agreement, Opnext may not, without Oclaro’s prior written consent, among other things: (i) declare, accrue, set aside, make or pay any dividend or other distribution with respect to any shares of its capital stock; (ii) acquire, repurchase or redeem any shares of its capital stock; (iii) issue, sell, or grant the authorization to issue or sell, any shares of its capital stock; or (iv) split, consolidate, subdivide, or reclassify any shares of its capital stock; in each case, except under limited circumstances as set forth in the Merger Agreement.

(f)	Upon consummation of the Merger, Opnext, as the surviving corporation in the Merger, will become a direct, wholly-owned subsidiary of Oclaro.

(g)	The Merger Agreement contains provisions that limit the ability of Opnext to engage in a transaction that would entail a change of control of Opnext (other than the transactions contemplated by the Merger Agreement) during the pendency of the transactions contemplated by the Merger Agreement.

(h)-(i)

Upon consummation of the Merger, the Opnext Common Stock will be delisted from the NASDAQ Global Market and will become eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act.

(j)	Other than as described above, Oclaro currently has no plans or proposals which relate to, or may result in, any of the matters listed in Items 4(a)-(i) of this Schedule 13D (although Oclaro reserves the right to develop such plans or proposals).

ITEM 5.

INTEREST IN SECURITIES OF THE ISSUER

(a)-(b)

As described in Item 4 (a)-(b) of this Schedule 13D, as a result of the Opnext Voting Agreements, Oclaro has the power to vote or to direct the vote of the Subject Securities with respect to the matters set forth in the Opnext Voting Agreements. Assuming the exercise of stock options exercisable within 60 days after March 26, 2012, as of such date the Subject Securities represented in the aggregate approximately 40.5% of the sum of (i) 90,405,097 shares of Opnext Common Stock represented by Opnext in the Merger Agreement to be outstanding as of March 23, 2012 and (ii) the Option Shares.

In addition, any shares of Opnext Common Stock acquired or received by any Opnext Supporting Stockholder after the date (and before the valid termination) of the Opnext Voting Agreements will also be subject to the terms of the Opnext Voting Agreements. Accordingly, any such acquisition or receipt of shares of capital stock of Opnext by any Opnext Supporting Stockholder may result in Oclaro being deemed to be the beneficial owners of such additional shares (the Opnext Common Stock subject to the Opnext Voting Agreements, the Option Shares and such additional shares being collectively referred to herein as the “Subject Securities”). However, Oclaro hereby disclaims beneficial ownership of such shares, and this Schedule 13D shall not be construed as an admission that Oclaro is, for any or all purposes, the beneficial owner(s) of any of the Subject Securities covered by this Schedule 13D.

Except as set forth in this Schedule 13D, no shares of Opnext Common Stock are beneficially owned by Oclaro, or, to the knowledge of Oclaro, any person listed on Schedule A to this Schedule 13D.

The foregoing summary descriptions of the Merger Agreement and the Opnext Voting Agreements do not purport to be complete and are qualified in their entirety by reference to the full text of the Merger Agreement and the form of the Opnext Voting Agreements, copies of which are attached as exhibits hereto or incorporated herein by reference.

(c)	Except as set forth in this Schedule 13D with reference to the Merger Agreement and the Opnext Voting Agreements, neither Oclaro nor, to the knowledge of Oclaro, any person named in Schedule A to this Schedule 13D, has effected any transaction in the Opnext Common Stock during the past 60 days.

(d)	To the knowledge of Oclaro, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Subject Securities.

(e)	Not applicable.

ITEM 6.

CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER

Other than as described in Items 3, 4 and 5, which are incorporated herein by reference, and in the agreements and documents attached as exhibits hereto or incorporated herein by reference, to the knowledge of Oclaro, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 or between such persons and any other person with respect to any securities of Opnext, including but not limited to transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, the existence of which would give another person voting or investment power over the securities of Opnext.
