Sorrento Networks Completes Acquisition of Zhone Technologies’ GigaMux Business Unit


DENVER – Jan. 23, 2008 – Sorrento Networks today announced it has completed the acquisition of the GigaMux product portfolio from 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.

Under terms of the agreement, the GigaMux product line and related services formerly offered by Zhone, including the GigaMux 50, GigaMux 1600/3200 and GigaMux 6400 are now offered and supported by Sorrento Networks.

“Sorrento Networks exists because the metro optical access market offers the opportunity for growth: growth in bandwidth, growth in services, growth in subscribers and growth in revenue,” said Jim Nevelle, co-founder and CEO of Sorrento Networks. “Our vision is to deliver growth potential to our customers by providing exceptional support for existing GigaMux products and also by expanding the GigaMux portfolio to offer new, advanced services and capabilities.”
