SANTA CLARA, Calif. -- PMC-Sierra, Inc. (Nasdaq:PMCS - News), the premier Internet infrastructure semiconductor solutions provider, today announced the availability of complete systems for symmetric 10Gbit/s IEEE 802.3av EPON, including Optical Line Terminals (OLT) and Optical Network Units (ONU). The Company will demonstrate these second-generation 10G EPON platforms in conjunction with the Optical Fiber Communication Conference and Exposition (OFC), March 23-26, 2009, at the Manchester Grand Hyatt Hotel in San Diego. After showcasing its asymmetric 10G EPON systems in 2008, the upcoming demonstration will feature PMC-Sierra’s symmetric 10G EPON systems, delivering 10Gbit/s downstream and 10Gbit/s upstream performance.

“PMC-Sierra’s 10G EPON solutions and the increased availability of optics supporting 10G rates have enabled carriers to begin trials,” said Raphael Sankar, vice president of marketing for PMC-Sierra’s Fiber to the Home Business Unit. “This performance will allow carriers to provide new services, such as the next level of HDTV broadcasting and advanced business offerings, while further reducing capital expenditures. With this demonstration of symmetric 10G EPON, PMC-Sierra continues to solidify its leadership position in FTTH silicon solutions for EPON and GPON, and now 10G EPON.”

PMC-Sierra has developed complete systems for symmetric 10G IEEE 802.3av EPON Optical Line Terminals (OLT) and Optical Network Units (ONU). The PAS8011 system for 10G OLTs and the PAS9011 system for 10G ONUs integrate all the functionality required from an OLT and ONU running at 10G rates, including transceivers, and leverage PMC-Sierra’s market-leading EPON capabilities and analog expertise.

As the next generation of PMC-Sierra’s market-leading EPON devices, these solutions are interoperable with more than seven million EPON ONUs deployed worldwide that are based on PMC-Sierra’s devices. This enables a smooth and gradual upgrade from 1G EPON to 10G EPON, while lowering carriers’ capital and operational expenditures.

PMC-Sierra’s 10G EPON solutions include backward-compatible Service Dynamic Bandwidth Allocation (DBA), which enables configurable high system performance in a multi-service environment for access, wireless backhaul and cable TV networks. The solutions are IEEE standard compliant and interoperable, following carrier requirements.
