This Amendment No. 3 to Schedule 13D amends and supplements the Statement on Schedule 13D filed on November 24, 2003, as amended (as amended, this “Schedule 13D”), filed with respect to the common stock (“Zhone Common Stock”) of Zhone Technologies, Inc, (“Zhone”). This Amendment No. 3 is the final amendment to the Schedule 13D and is an exit filing.

Item 5.

Interest in Securities of the Issuer.

Item 5 is hereby amended in relevant part as follows:

As of the close of business on April 27, 2011, KKR–ZT, L.L.C. (“KKR-ZT”) holds of record an aggregate of 1,511,080 shares of Zhone Common Stock. These shares represent approximately 4.9% of the outstanding shares of Zhone Common Stock, based on an aggregate of 30,612,500 shares of Zhone Common Stock outstanding as of March 14, 2011, as reported in Zhone’s Proxy Statement on Schedule 14A (File No. 000–32743) filed with the Securities and Exchange Commission on March 30, 2011. As the senior member of KKR–ZT, KKR 1996 Fund L.P. (“KKR Fund”) may be deemed to be the beneficial owner of such shares of Zhone Common Stock held by KKR–ZT. As the sole general partner of KKR Fund, KKR Associates 1996, L.P. (“KKR Associates”) also may be deemed to be the beneficial owner of such shares of Zhone Common Stock held by KKR–ZT. As the sole general partner of KKR Associates, KKR 1996 GP LLC (“KKR GP”) also may be deemed to be the beneficial owner of such shares of Zhone Common Stock held by KKR–ZT. KKR GP, acting through each of KKR Associates, KKR Fund and KKR–ZT, has the sole power to vote or direct the vote, and to dispose or to direct the disposition of the shares of Zhone Common Stock reported hereby.

Each of Henry R. Kravis and George R. Roberts, as managers of KKR GP, may be deemed to share beneficial ownership of any shares of Zhone Common Stock that KKR GP may beneficially own or be deemed to beneficially own, but disclaims beneficial ownership of these securities. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any individual named in Item 2 above is the beneficial owner of the any shares of Zhone Common Stock reported hereby for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, or for any other purpose.

KKR–ZT, KKR Fund, KKR Associates, KKR GP, Mr. Kravis and Mr. Roberts are collectively referred to herein as the “Reporting Persons.”

From February 26 through April 27, 2011, KKR-ZT sold an aggregate of 180,193 shares of Zhone Common Stock in a series of transactions on the Nasdaq Global Market, as described in Appendix A. Except as described herein, there have not been any transactions in the shares of Zhone Common Stock effected by or for the account of the Reporting Persons during the 60 days prior to the date of this Schedule 13D.

To the best knowledge of the Reporting Persons, 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 shares of Zhone Common Stock owned by KKR–ZT.

On April 27, 2011, the Reporting Persons ceased to be the beneficial owners of more than five percent of the class of securities reported herein.
