Advanced 10G-EPON OLT System-on-Chip Features Integrated Traffic Management, Packet Processing, In-Band OTDR, Enhanced Networking Functionality and Power Save Control

SUNNYVALE, Calif., Mar 07, 2011 (BUSINESS WIRE) -- PMC-Sierra, Inc. (Nasdaq:PMCS) today announced 10G-EPON OLT devices with industry-leading traffic management, packet processing, on-chip redundancy and the industry's most advanced optical diagnostic technologies. PMC-Sierra's 10G-EPON OLT family complies with IEEE 802.3av specifications and China carrier specifications for both asymmetric and symmetric 10G-EPON modes. The devices provide the highest network reliability and Quality of Service (QoS), and are the first to integrate a complete, always-on toolkit for optical network and ONU inspection. The toolkit consists of an in-band Optical Time Domain Reflectometer (OTDR) and Upstream Signal Analyzer, that operate while in-service, reducing the need for external test equipment. On-chip fiber Automatic Protection Switching (APS) enables a rapid switch-over in cases of failure in the optical distribution network (ODN).

"10G-EPON allows carriers to meet the demand for enhanced triple-play services and ever-increasing bandwidth requirements, while doubling the number of users supported over the same fiber infrastructure," said Raphael Sankar, vice president and co-general manager of PMC-Sierra's FTTH division. "Our integrated traffic management, packet processing, break-through optical diagnostics and built-in Power Save Control enable customers worldwide to deliver feature-rich, reliable and cost-effective solutions."

PMC-Sierra's enhanced QoS exceeds China Telecom specifications, including IPv6 protocol support. The integrated traffic management and packet processing eliminates the need for high-power, low-density external traffic management processors and enables the largest number of subscriber connections with best-in-class QoS. A sophisticated queuing system lowers the cost of deployment and reduces power by enabling a loss-less power save implementation at the EPON and 10G-EPON ONUs.

"We expect 10G EPON shipments to pick up significantly in 2011 among major operators in the Asia Pacific region," said Jeff Heynen, directing analyst, Broadband Access, at Infonetics Research. "Whether it's increasing bandwidth per subscriber or increasing the number of subscriber splits, operators will gradually transition to 10G for all their major FTTX deployments."

Key Features of PMC-Sierra's 10G-EPON Solutions

PMC-Sierra's 10G-EPON devices comply with the IEEE 802.3av standard and the China carrier standards. They integrate 10Gb/s and 1Gb/s upstream and downstream PON channels, including the EPON/10G-EPON MAC, SERDES and fast-locking Burst Mode CDR (BMCDR), a wire-speed advanced traffic manager and classifier with thousands of user and service queues and XAUI and RXAUI backplane interfaces. The advanced Optical Diagnostic Unit implements OTDR and ONU signal analysis. On-chip synchronization techniques, compliant with IEEE 1588v2, Synchronous Ethernet and Time of Day (ToD) delivery enable connecting Mobile Backhaul to the 10G-EPON network. The devices integrate an embedded powerful CPU subsystem for control, link management and programmable Dynamic Upstream Bandwidth Allocation (DBA) algorithm and support ONU power saving modes, which lower PON deployment costs by reducing electricity and battery backup unit costs.

The devices are:

-PAS8301 asymmetric 10G-EPON OLT;

-PAS8311 asymmetric 10G-EPON OLT with integrated traffic management;

-PAS8401 symmetric 10G-EPON OLT, and;

-PAS8411 symmetric 10G-EPON OLT with integrated traffic management.

PMC-Sierra's OLT solutions include reference designs and software design kits (SDK). The complete 10G-EPON OLT software package, is compatible with PMC-Sierra's EPON OLT software and is portable to any real-time operating system, such as Linux and VxWorks, and to any processor. The SDK features a 10G-EPON protocol stack, a complete set of traffic management drivers, IEEE 802.3av/ah OAM protocol including operator-specific stacks, optical diagnostics functions, and pre-integrated peripheral drivers.

Availability and Customer Support

The OLT device family reference designs will be available in the second quarter of 2011 to select customers. For pricing and delivery information, contact a PMC-Sierra sales representative at A comprehensive support package, including datasheets and application notes, is available at
