ZTE Corporation 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. 

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.”
