Bandwidth Breakthrough with the Use of Copper Lines in Data Networks

21st October 2010, Shenzhen – ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a leading global provider of telecommunications equipment and network solutions, today announced the launch of the world's first system-level VDSL2 vectoring prototype - ZXDSL 9836. By leveraging system-level vectoring technology, the transmission and reception signals on every copper can be collectively processed in the central vectoring engine of the ZXDSL 9836, therefore eliminates crosstalks between copper pairs of the whole system, and improves the VDSL performance at the system level.

The ZXDSL 9836 automatically analyzes interference between line pairs and eliminates the major interference, achieving 100M data downstream speeds through copper lines. It is a significant breakthrough that paves the way for the commercial use of copper lines in large-scale network deployments.  

Through the innovation of system-level vectoring technology, ZTE is able to increase the capacity of copper wires, extend the network's reach and prolong the life cycle of copper cables, making it possible for VDSL2 vectoring technology to progress from a laboratory concept to actual commercial application.

The introduction of the special vectoring card allows equipment to be smoothly upgraded and configured to support vectoring. ZTE's ZXDSL 9836 compact DSLAM can support up to 192 VDSL2 lines with centralized system-level vectoring. It provides vectoring for all access lines from the same remote access node in a number of application modes from small-capacity FTTB (Fiber-to-the-Building) projects to large-capacity FTTC (Fiber-to-the-cabinet) deployments, which cannot be achieved by current card-level vectoring solutions.

"Years of commercial use proves that DSL technology still has a long life cycle ahead," said Xu Ming, ZTE Vice President and Fixed-Line Product Line General Manager. "By drawing on the strength of a 3000-strong team in fixed-line broadband access R&D, ZTE is able to track technological advances and innovate in this field and rapidly bring new technologies to market to help generate more commercial value for our customers."

Separately, ZTE continues to hold the number one ranking in terms of DSL market share growth worldwide in 2010, according to telecommunications consultancy Ovum. In 2009, ZTE was ranked third in terms of market share, accounting for 22% of the global market.

According to Ovum's report "Global FTTx and DSL Broadband Access Markets", in 2009 ZTE accounted for 16.5% of the global market in terms of revenue and was ranked second among major vendors.

In addition, as a vendor that leads the world in developing and commercializing optical access network products, ZTE has a profound understanding and accurate positioning of xPON technologies.
