Broadcom announces Octal 10GbE SFP+ PHY ethernet physical layer transceiver

Broadcom today announced the 10GbE eight-channel, front panel Ethernet physical layer transceiver (PHY). The new Broadcom® BCM84780 Octal SFI-XFI PHY establishes higher bandwidth data center and enterprise network performance and server virtualization while reducing chip size and power by approximately 25 percent. The addition of the BCM84780 extends Broadcom's portfolio of single, dual, quad and now octal channel SFP+ physical layer devices. Optimized for data centers and enterprise networks that are transitioning to 10GbE and server virtualization, the BCM84780 octal PHY is approximately 25 percent smaller with lower power per port compared to other currently available solutions. The PHY features eight fully independent channels with IEEE 1588 timestamping. It also incorporates EDC that enables data to be transmitted on a 10GbE serial interface for applications requiring transmission over multimode fiber (MMF) at distances up to 300m (LRM) using OM3 fiber and SFP+ copper twin-axial cable (CR).
