Broadcom Corporation announced the industry's first 28 nanometer (nm) electronic dispersion compensation (EDC) physical layer transceiver (PHY) with support for long reach multimode (LRM). This latest addition to Broadcom's portfolio of 1/10/40GbE physical layer devices delivers significant power savings while boosting performance.
Demand for increased bandwidth for processing and transmission of data is driving the need for higher performance and port density with lower power per port. Broadcom's new PHY provides a 30 percent reduction1 in power consumption together with an enhanced feature set and a flexible footprint-compatible migration path for enterprise and service provider networks seeking higher performance and greater bandwidth capacity.
"With increasing bandwidth and traffic demands being placed on the network, product migration to smaller geometries enabling reduced power consumption continues to be critical to our customers," said Lorenzo Longo, Broadcom, Vice President and General Manager, Physical Layer Products. "Broadcom is committed to continue investing in this technology to roll out lower power EDC/LRM PHY devices with advanced feature sets."
The BCM82780, based on EDC technology, enables 10/40GbE data transmission with LRM support. It also handles short range (SR), long range (LR) and extended range (ER and ZR) optical interfaces for added flexibility supporting a broad range of high-bandwidth applications. The multirate PHY is ideal for single mode fiber (SMF), multi-mode fiber (MMF) or copper twin-axial applications on the front panel. It features an all-DSP high-speed front end, which provides the highest performance and flexibility for line-card designers across 40GbE, 10GbE or 1GbE systems.
