Zhone Concentrates R&D, Manufacturing and Marketing on Pure-Play Access Strategy

Zhone's Focus on FTTx, EFM, and MSAP Underscored by Divestiture of Accessnode and Gigamux Product Lines

Oakland, CA — January 23, 2008 — Zhone Technologies, Inc. (NASDAQ: ZHNE), a global provider of advanced communications equipment and a leading supplier for VoIP, IPTV, and Ethernet over copper and fiber access lines, today announced the divestiture of the AccessNode and GigaMux product lines. The move solidly positions Zhone as a pure play in the access market, where the company is realizing strong growth in its multi-service access portfolio as the industry accelerates away from legacy infrastructures. Zhone will concentrate full R&D, manufacturing, and marketing resources on the growth core of its business, adding to its portfolio of high-demand access solutions — including Ethernet in the First Mile (EFM) and Gigabit Passive Optical Networks (GPON) — while continuing to introduce key multi-service access platform (MSAP) enhancements throughout the this year. This move targets Zhone's strategy exclusively on access solution markets that Broadbandtrends.com, Dell'Oro and Infonetics (the industry analysts following the segment in detail) are forecasting to continue on more than a 40% compound annual growth trajectory through 2010.

"As an innovation-driven organization, Zhone's expertise and enthusiasm have always been centered on new technologies that advance communications and move the access industry forward," said Mory Ejabat, Zhone's chairman and CEO. "These divestitures enable us to focus maximum resources on continuing to enhance and extend our unmatched portfolio of integrated multi-service access products, bringing ever greater efficiency, speed, and operational agility to the access network."

"The sharpening of Zhone's focus on pure IP-based access technologies is timed right and is in sync with the evolution of the market at large, particularly in EMEA and emerging markets where Zhone is realizing strong growth," said Teresa Mastrangelo, principal analyst for Broadbandtrends.com. "They will realize operational gains throughout their organization, which in combination with the strength of their current portfolio of access solutions will bolster their position among the first-tier suppliers in multi-service access."

Partners in the Divestitures
Communications Test Design, Inc. (CTDI) has acquired Zhone's AccessNodeTM product suite. The sale includes the AccessNode, AccessNode Express, and the Universal Edge 9000 (UE9000) products. As the current service and repair contractor for the AccessNode products, CTDI is uniquely qualified to provide continued sales and outstanding customer support for the product family. CTDI also purchased the eLuminant line of products from Zhone in September of 2005.

The GigaMux 50, 1600/3200 and 6400 products have been acquired by the new Sorrento Networks, a global provider of metro optical access solutions. The GigaMux acquisition provides Sorrento with a complete solution-based approach to metro/regional wavelength-division multiplexing (WDM). Sorrento will provide service and support to all existing GigaMux customers worldwide, and is focusing research and development efforts to expand its portfolio of edge-to-regional CWDM, DWDM and ROADM solutions for carriers and enterprises.

Zhone's customers will continue to benefit from both companies commitment and ongoing support to the AccessNode and GigaMux product lines.

"Zhone continues to experience strong growth in new product revenue from our market leading MSAP with next generation access capabilities like EFM and GPON," said Kirk Misaka, CFO for Zhone. "The divestitures enable Zhone to concentrate resources on the high-growth core of our business."

AccessNode
