Chipset delivers 1 Gbit/s over copper cabling

The BCM65200 DSP and BCM65900 analog front end chipset is said to provide the industry’s highest density, lowest-power for G.fast connections over copper wiring, with bandwidth up to 1 Gbit/s per twisted pair. The chipset is intended for the CO side connections and includes 10G-KR vectoring noise cancellation.

The chip set features a state-of-the-art DSP architecture and support up to 36 lines of VDSL2 or six lines of G.fast, plus high-speed vector interfaces that eliminate the need for external PHY and framing devices. The ICs have simultaneous support of G.fast, G.vector, VDSL2 and ADSL protocols on a per line basis. G.fast promises to support a data rate of 1 Gbit/s over copper networks with runs of less than 50 meters and is often used with fiber to the home networks. Samples available now.
