Beneficial ownership of the common stock referred to herein is being reported hereunder solely because Zhone Technologies, Inc. may be deemed to beneficially own such shares as a result of the Voting Agreement described in Item 4 below. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by Zhone Technologies, Inc. that it is the beneficial owner of any of the common stock referred to herein for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, or for any other purpose, and such beneficial ownership is expressly disclaimed.

(2)

The calculation of the foregoing percentage is based on (a) 16,743,320 shares of Sorrento Networks Corporation common stock outstanding as of April 22, 2004, as set forth in the Merger Agreement (as described in Item 4 below), plus (b) 1,147,318 shares issuable upon exercise or conversion of securities exercisable for or convertible into Sorrento Networks Corporation common stock that are subject to the Voting Agreement.

Item 1.

Security and Issuer.

This statement on Schedule 13D relates to shares of common stock, par value $0.001 per share (the “Company Common Stock”), of Sorrento Networks Corporation (the “Company”), whose principal executive offices are located at 9990 Mesa Rim Road, San Diego, California 92121. The telephone number of the Company is (858) 558-3960.

Item 2.

Identity and Background.

The Reporting Person filing this statement is Zhone Technologies, Inc., a Delaware corporation (“Zhone”), whose principal offices are located at 7001 Oakport Street, Oakland, California 94621. The telephone number of Zhone is (510) 777-7000. Zhone creates network products supporting voice, data, video and entertainment services.

The names, citizenship, business addresses, present principal occupation or employment and the name, principal business address of any corporation or other organization in which such employment is conducted, of the directors and executive officers of Zhone are set forth in Schedule A hereto and incorporated herein by this reference.

Neither Zhone, nor, to its knowledge, any person listed in Schedule A, has during the past five years been (1) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (2) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3.

Source and Amount of Funds or Other Consideration.

As described in Item 4, the Company Common Stock to which this statement relates has not been purchased by Zhone. As an inducement for Zhone to enter into the Merger Agreement described in Item 4 and in consideration thereof, certain stockholders of the Company identified in Item 4 entered into a voting agreement dated as of April 22, 2004 (the “Voting Agreement”), with respect to an aggregate of 1,171,980 shares of Company Common Stock (the “Shares”).

Zhone has not paid, and does not expect to pay, additional consideration in connection with the execution and delivery of the Voting Agreement. For a description of the Voting Agreement, see Item 4 below, which description is incorporated herein by reference in response to this Item 3. The Voting Agreement is filed herewith as Exhibit 2, by reference to its filing as Exhibit 99.3 to the Current Report on Form 8-K filed by Zhone on April 23, 2004.

Item 4.

Purpose of Transaction.

On April 22, 2004, Zhone entered into a definitive Agreement and Plan of Merger (the “Merger Agreement”) with the Company and Selene Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of Zhone (“Merger Sub”). The Merger Agreement was approved by the board of directors of each of Zhone, Merger Sub and the Company. Pursuant to the Merger Agreement and subject to the terms and conditions set forth therein, Merger Sub will merge with and into the Company, with the Company surviving as a wholly-owned subsidiary of Zhone (the “Merger”). At the effective time of the Merger, each outstanding share of Company Common Stock will be exchanged for 0.9 of a share of Zhone’s common stock, par value $0.001 per share (the “Zhone Common Stock”), and each option, warrant and other security exercisable or convertible into shares of Company Common Stock will be assumed by Zhone and become exercisable or convertible into shares of Zhone Common Stock, with appropriate adjustments to reflect the Merger. The Merger, which is structured to qualify as a tax-free reorganization, is subject to the approval of the stockholders of both Zhone and the Company and other customary closing conditions. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in the Merger Agreement.

Page 3 of 6

Concurrently with the execution of the Merger Agreement, Zhone entered into a Voting Agreement with the following persons (collectively, the “Company Stockholders”) who beneficially own an aggregate of 1,171, 980 shares, or approximately 6.6% of the Company Common Stock outstanding as of the date of the Merger Agreement: Phillip W. Arneson, Joe R. Armstrong, Donne F. Fisher, Robert L. Hibbard, Gary M. Parsons, Larry J. Matthews, Don Herzog and Tom Schilling.

Pursuant to the Voting Agreement, each Company Stockholder has agreed to vote all of the shares of Company Common Stock beneficially owned by such Company Stockholder (1) in favor of the Merger, the adoption by the Company of the Merger Agreement and the approval of the other transactions contemplated by the Merger Agreement and (2) against (a) any Alternative Transaction or (b) any Frustrating Transaction. The Voting Agreement terminates upon the earlier of (1) the effective time of the Merger or (2) the date upon which the Merger Agreement is terminated pursuant to Section 7.1 thereof.

The Voting Agreement also provides, among other things, that each Company Stockholder will not: (1) except as otherwise set forth therein, sell, transfer, pledge, assign or otherwise dispose of, or enter into any contract, option or other arrangement (including any profit-sharing arrangement) or understanding with respect to the sale, transfer, pledge, assignment or other disposition of, any of the Company Common Stock held by such Company Stockholder, (2) enter into any voting arrangement, whether by proxy, voting agreement, voting trust, power-of-attorney or otherwise with respect to any of the Company Common Stock held by such Company Stockholder, (3) take any other action that would in any way restrict, limit or interfere with the performance of his obligations under the Voting Agreement or the transactions contemplated thereby, or take any action that would make his representations or warranties under the Voting Agreement untrue or incorrect in any material respect and (4) until the Merger is consummated or the Voting Agreement is terminated, permit any of his representatives to (a) solicit, initiate or encourage (including by way of furnishing nonpublic information), or take any other action designed to, or which could reasonably be expected to facilitate an Acquisition Proposal with respect to the Company, or the making, submission or announcement of any such Acquisition Proposal with respect to the Company or (b) participate or engage in any discussions or negotiations regarding, or furnish to any person any nonpublic information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes or could reasonably be expected to lead to, any Acquisition Proposal with respect to the Company or (c) engage in any discussions with any person with respect to any Acquisition Proposal with respect to the Company, except to notify such person as to the existence of the Voting Agreement. Each Company Stockholder and each of his affiliates shall immediately cease and cause to be terminated any existing discussions or negotiations with any persons (other than Zhone) conducted before the date of the Voting Agreement with respect to any of the foregoing.

In connection with the Voting Agreement, each Company Stockholder also delivered to Zhone an irrevocable proxy with respect to the securities held by such Company Stockholder, allowing Zhone’s designee to vote in favor of the Merger, the adoption by the Company of the Merger Agreement and the approval of all of the other transactions contemplated by the Merger Agreement and against any Alternative Transaction or Frustrating Transaction.

References to, and descriptions of the Merger Agreement and Voting Agreement in this Item 4 are qualified in their entirety by this reference to the Merger Agreement and the Voting Agreement, which are filed as Exhibits to this Schedule 13D and which are incorporated by reference in this Item 4 in their entirety where such reference and descriptions appear.

Item 5.

Interest in Securities of the Issuer.

(a)-(b)

The number of shares of Company Common Stock subject to the Voting Agreement is 1,171,980 (representing approximately 6.6% of the voting power of (1) 16,743,320 shares of Company Common Stock outstanding as of April 22, 2004, as set forth in the Merger Agreement, plus (2) 1,147,318 shares issuable upon exercise or conversion of securities exercisable for or convertible into Company Common Stock that are subject to the Voting Agreement).

Page 4 of 6

By virtue of the Voting Agreement, Zhone may be deemed to share with the Company Stockholders the power to vote the Shares, but only as to the matters specified in the Voting Agreement. Except as stated in the preceding sentence, Zhone does not have the power to vote or to direct the vote of the Company Common Stock, nor does it have the sole or shared power to dispose or to direct the disposition of the Company Common Stock.

To the knowledge of Zhone, no shares of Company Common Stock are beneficially owned by any of the persons named in Schedule A.

(c)	Except for the Merger Agreement and the Voting Agreement, and the transactions contemplated by those agreements, neither Zhone, nor to Zhone’s knowledge, any of the persons listed on Schedule A, has effected any transaction relating to the Company Common Stock during the past 60 days.

(d)-(e)

Not applicable.

Item 6.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

The information set forth, or incorporated by reference, in Items 3 through 5 of this statement is hereby incorporated by reference in this Item 6. To Zhone’s knowledge, except as otherwise described in this Schedule 13D, there are no contracts, arrangements, understandings or relationships among the persons named in Item 2 above or listed in Schedule A hereto, and between any such persons and any other person, with respect to any securities of the Company, including but not limited to, transfer or voting of any of the securities of the Company, joint ventures, loan or option arrangements, puts or calls, guarantees or profits, division of profits or loss, or the giving or withholding of proxies, or a pledge or contingency the occurrence of which would give another person voting power over the securities of the Company.
