PMC-Sierra Introduces Multi-Rate PHY/Framers

PMC-Sierra introduced two new devices that offer a physical layer solution for simultaneously aggregating, transporting and terminating OC-3/STM-1, OC-12/STM-4, and OC-48/STM-16 Packet-over-SONET (POS) and ATM traffic on a single line card. The S/UNI MULTI devices are designed for use in physical interfaces to connect network elements that demand rapid bandwidth expansion like DSLAMs, CMTSs, and wireless base-station controllers, edge routers and multi-service switches. PMC-Sierra said a single multi-rate line card powered by one S/UNI MULTI-48 device, in conjunction with available multi-rate or pluggable optics modules, could replace up to three line card designs. Marconi is utilizing PMC-Sierra’s S/UNI MULTI-48 in its BXR-48000 multiservice switch router.http;//www.pmcsierra.com
