Zhone Technologies Unveils New VDSL2 Vectoring Card at FTTH London
Global leader in FTTx network access solutions adds MXK VDSL2 48-port line
card

Oakland, CA - Feb 19, 2013 - Zhone Technologies, Inc. (NASDAQ: ZHNE), a global
leader in FTTx network access solutions, today announced that it has expanded
its MXK Multi-Service Access Platform to include the new MXK VDSL2 48-port
line card, which will be launched at FTTH Conference 2013, London (February
19- 21; Zhone booth S15). The new vectoring card gives operators the ability
to take advantage of VDSL2 vectoring for fiber-like speeds over current copper
infrastructure. While speeds vary, VDSL2 can deliver asymmetric and symmetric
aggregate data rates up to 200Mbps downstream and upstreamon twisted copper
pairs.

The emergence of VDSL2 vectoring provides great opportunity for service
provides across the globe and will be a topic of focus at this year's FTTH
Conference taking place in London. According to a recent report by RVA, the
annual direct investment in FTTH networks will reach $4.7 billion by 2017 and
total investment in FTTH over the next five years will be $18 billion. Main
drivers for this include: the delivery of multiple HDTV channels, second
screen viewing, and the ever-increasing popularity of video sharing. This
creates mounting pressure on traditional asymmetric digital subscriber line
(ADSL)-based access networks to meet the rapidly growing bandwidth demand -
which account for approximately two-thirds of broadband subscriber lines
worldwide.

Zhone's VDSL2 vectoring card is a high-density high-bandwidth module for the
MXK 819/823 and MXK 319 chassis and provides a viable solution for operators
looking to provide competitive download and upload speeds. The Broadcom-based
card supports up to profile 17a, as well as ADSL2 fallback, link bonding and
vectoring and ADSL compatibility, allowing service providers to provide both
VDSL and ADSL service.

"Vectoring enables millions of households and workplaces to have fiber-like
speed over copper lines," said Brian Caskey, chief marketing officer at Zhone.
"The high performance levels seen through the latest VDSL2 cards increase
bandwidth and give operators the means to address competitive and regulatory
challenges, while they prepare their networks for the migration to fiber."

In a recent report on VDSL2 and vectoring,Broadbandtrends forecasts that 27
percent of all cumulative VDSL2 ports will be vectored by the year 2017. EMEA
represents the largest opportunity with 45 million VDSL2 ports.

In addition to providing high-speed downloads and uploads, VDSL2 vectoring
also identifies crosstalk interference and records findings in a Channel
Crosstalk Matrix at the Vectoring Control Entity (VCE). Utilizing noise and
interference cancelling DSP technology, the solution eliminates the most
dominant disturber - self Far End Crosstalk (self-FEXT). Self-FEXT
cancellation techniques are particularly beneficial with short cable lengths,
less than one km. Any VDSL2 line in the vector group can operate as if it were
the only active line in the binder group.

Zhone's FiberHome portfolio of products and solutions, which includes the MXK
platform, fulfills the network requirements of both international and domestic
customers' broadband expansion efforts for residential users. Additionally,
growing opportunities in business services delivery provide ongoing prospects
for Zhone to further globally deploy the MXK with the company's FiberLAN
solution.

various applications, including VDSL vectoring, please visit Zhone at booth
S15 during the FTTH Conference 2013 in London.
