PMC-Sierra Introduces Industry's First 10G EPON Reference Designs for FTTH Deployments

PAS8001 10G OLT and PAS9001 10G ONU Deliver Complete 10Gbit/s EPON
Reference Designs Enabling System Vendors and Carriers to Offer Next
Generation FTTH Solutions
SANTA CLARA, Calif.--(Business Wire)--
PMC-Sierra, Inc. (Nasdaq:PMCS) today announced the availability of
complete reference designs for 10Gbit/s IEEE 802.3av EPON Optical Line
Terminals (OLT) and Optical Network Units (ONU). The PAS8001 reference
design for 10G OLTs and the PAS9001 reference design for 10G ONUs
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.

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 10G EPON development platform enables our customers
to be the first to offer carriers 10G solutions that are fully
interoperable with legacy PON equipment, and a cost-effective,
standard upgrade path for their next generation access network
infrastructure," said Victor Vaisleib, vice president and general
manager of PMC-Sierra's FTTH business unit.

The PAS8001 and PAS9001 deliver 10Gbit/s performance, pre-standard
(draft 1.1) 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 1G
EPON devices, these solutions fully coexist with more than six million
EPON ONUs deployed worldwide that are based on PMC-Sierra's devices.

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. For more information, contact PMC-Sierra at

About PMC-Sierra's FTTH Family of Products

PMC-Sierra is the only supplier to support both EPON (IEEE 802.3ah
Ethernet in the First Mile) and GPON (ITU-T G.984) standards. The
Company's gigabit PON products are based on the robust GigaPASS(TM)
FTTH Architecture that achieves sustained gigabit and greater data
rates while providing a powerful 32-bit programmable processing engine
executing the real-time operating system, middleware, and
application-specific firmware required for high-performance FTTH
network access functions. PMC-Sierra system-on-chip solutions provide
end-to-end gigabit per second bandwidth solutions linking central
office equipment and customer premise equipment. Optical line terminal
(OLT) devices connect the central office to the PON network and
optical network unit (ONU) or optical network terminal (ONT) devices
connect customer premises to the PON network. For more information,
