ZTE Corporation has announced the launch of the world’s first system-level VDSL2 vectoring prototype, the ZXDSL 9836. The ZXDSL 9836 automatically analyses 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 centralised 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 prove that DSL technology still has a long life cycle pahead,” said Xu Ming, vice President ZTE and general manager, fixed-line product line. “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.”
