 Zhone Technologies Introduces a New High Performance Uplink Card Building on
                   the Momentum of its Industry Leading MXK

Leader in FTTx network access solutions shows continued traction with more
than 4,600 MXK's shipped

Oakland, CA - June 4, 2013 - Zhone Technologies, Inc. (NASDAQ: ZHNE), a global
leader in FTTx network access solutions, announced the release of the newest
version of its MXK High-performance Uplink card with new innovation in
hardware architecture that essentially doubles the network facing uplink
capacity. The new uplink card was designed to enable operators to offer
superior high-bandwidth services in a variety of different networks by
offering a wide range of available service types and features. This will allow
operators to offer superior high-bandwidth services with models that support
both copper and fiber small form-factor pluggable transceivers (SFPs).
Additionally, the MXK uplink card provides full network redundancy by
supporting both an active card and a backup standby in the same chassis. If a
card or network failure occurs, the standby card will take over without
dropping any calls.

Zhone continues to generate substantial growth in global deployments of its
industry-leading MXK(TM) multi-service access node (MSAN), shipping a total of
4,676 MXK's across the globe by the end of Q1 2013. Demonstrating continued
market leadership, Zhone has continued to focus its deployment efforts on its
Gigabit Passive Optical Network (GPON), Active Ethernet (AE) and
Very-High-Bit-Rate Digital Subscriber Line (VDSL2) technologies, with a GPON
subscriber capacity of 32.5 million.

"Zhone's continued emphasis on expanding its product line and FTTx network
access solutions reinforces the company's position as a global leader in the
market," explained Brian Caskey, chief marketing officer at Zhone
Technologies. "Zhone is extremely dedicated to providing its diverse customer
base with leading-edge fiber solutions that drive broadband in global markets
and provide impressive and adaptable service offerings that allow customers to
enhance their services and remain competitive."

Known for its strong market leadership and product innovation, Zhone is
expanding its customer base across the Middle East, Central and Latin America,
Europe and North America. Zhone continues to provide fiber solutions that are
flexible and able to meet the unique needs of customers' networks.

"This quarter, Broadbandtrends ranked Zhone number two in the EMEA region for
GPON revenue and OLT port shipments, and number five globally, showcasing the
MXK's continued momentum in both domestic and international markets," said
Teresa Mastrangelo, principal analyst at Broadbandtrends. "Zhone's MXK
platform provides customers with extensive opportunities for network and
service expansions, enhancing the value of their services."

Featuring industry-leading density, scalability and switching capacity, the
MXK is the industry's first terabit access concentrator and provides
non-blocking capacity of up to 3,600 100 Mbps GPON subscribers or 360 1G
Active Ethernet subscribers. Zhone's ONT deployment growth has also increased
at a CAGR of 228 percent since Q1 2009, while MXK OLT has grown at a CAGR of
232 percent.
