Optimised for next-gen cloud-scale data centre, enterprise and core networks, Broadcom claims that the BCM82792 is the industry's highest performance, lowest power multi-rate 100GbE gearbox physical layer transceiver (PHY). The device offers dual 100Gbps ports on a single gearbox chip, increasing the density while reducing power consumption (2W per port).

The BCM82792 can to multiplex and demultiplex data across eight 25Gbps channels to (or from) twenty 10Gbps channels. Suiting high-bandwidth networks, the PHY is configurable to support eight bi-directional lanes at 10Gbps for 10 or 40GbE pass-through applications. Routing constraints are eased with high performance 25/10G IO providing longer physical links.

Lorenzo Longo, Vice President and General Manager, Physical Layer Products, Broadcom, comments: "Next generation 100G networks demand the high performance, low power technologies that Broadcom is uniquely positioned to deliver. These first to market gearbox devices demonstrate our commitment to providing superior innovation and delivering a comprehensive portfolio of products to enable high density 100G networks."

"We're seeing strong demand for higher bandwidth solutions in data centre, enterprise and core networks to handle the growth in network traffic. The higher density and low power consumption of Broadcom's new PHY will allow network managers to transform their networks and achieve higher performance on the industry's most widely adopted copper and short range links," adds Matthias Machowinski, Infonetics Directing Analyst, Enterprise Networks.

Broadcom's BCM82792 dual port and gearbox PHYs are available now for sampling.
