PMCS (MM)

PMC-Sierra, Inc. (Nasdaq:PMCS) today announced the industry�s first demonstration of 10Gbit/s IEEE 802.3av EPON. The demonstration � based on PMC-Sierra�s complete reference designs for 10Gbit/s EPON, which include the PAS8001 for 10G Optical Line Terminals (OLT) and the PAS9001 for 10G Optical Network Units (ONU) � was conducted at OptiNet China, May 28-29, in Beijing, China. The reference designs integrate all the functionality required from an OLT and ONU running at 10Gbit/s, including third-party commercial transceivers, and leverage PMC-Sierra�s market-leading EPON capabilities to improve system performance and reduce OEMs� time to market. �CTC developed an EPON enterprise standard that has driven chipset and equipment vendors to ensure their solutions successfully achieve interoperability with it,� said Wang Bo, senior business associate manager of the Technical Department of China Telecom (CTC). �As a result, we have started quantity deployment. We are very interested in the new 10G EPON specification, IEEE 802.3av, and look forward to a version supporting unique CTC features, ensuring 10G EPON interoperability and a future smooth upgrade path from 1G EPON.� The availability of 10Gbit/s EPON systems will enable carriers to further expand their Triple Play services, Fiber-To-The-Building (FTTB) solutions, and lay the foundation for future bandwidth-demanding applications. In addition, carriers will be able to reduce capital and operating expenses by unifying their FTTH and FTTB infrastructures. PMC-Sierra�s PAS8001 and PAS9001 deliver 10Gbit/s performance, pre-standard IEEE 802.3av compliance, 1G/10G co-existence with auto-detect, standard encryption, high performance backward-compatible Dynamic Bandwidth Allocation (DBA) and commercially viable transceivers developed by a leading transceiver vendor partner. PMC-Sierra�s 10G solution can operate in a split ratio of up to 128 ONUs per OLT. As the next generation of PMC-Sierra�s market-leading EPON devices, these new solutions coexist with more than six million EPON ONUs deployed worldwide that are based on PMC-Sierra�s devices. 10G EPON White Paper �10G EPON Brings Advantages to the Fiber Access Network,� a white paper that details how 10G EPON technology will spur deployment of next-generation HD IPTV and other high-bandwidth applications, by Lior Khermosh, chief system architect for PMC-Sierra�s FTTH business and Gilad Aloni, PMC-Sierra EPON product manager, is available for download at http://www.pmc-sierra.com/ftth-pon (registration required). Availability and Customer Support The PAS8001 development kit for 10G OLTs and PAS9001 development kit for 10G ONUs, both FPGA-based, are available now for purchase orders.
