PM5420 HyPHY, PM5426 HyPHY

PMC-Sierra Inc. launched the PM5420 HyPHY 20G and PM5426 HyPHY 10G devices that enable convergence of high-bandwidth data, video and voice services over optical transport network-based (OTN) Metro infrastructures.

OTN is the replacement technology for SONET/SDH, providing optimized transport of IP services. The global transition, however, has been delayed by the need for low-power, cost-effective service gateways with simultaneous protocol support for Carrier Ethernet, video, storage area network (SAN), OTN and SONET/SDH at the network edge. PMC-Sierra's HyPHY products can reduce line card variants by 75 percent, achieve 50 percent power savings and deliver multiservice aggregation flexibility to accelerate the transition to IP-optimized OTNs. OEMs can now deliver reconfigurable optical add-drop multiplexer (ROADM), optical transport platform (OTP) and micro OTP equipment that addresses carriers' technical requirements and reduces operational and capital expenditures.

"With FLASHWAVE 9500's fusion of connection-oriented Ethernet, ROADM and SONET/SDH transport, Fujitsu defined a new category of optical transport equipment, and PMC-Sierra has provided key innovations to enable it," said Rod Naphan, VP of product and strategic planning at Fujitsu Network Communications. "HyPHY 20G offers advanced mapping and multiplexing capabilities that enable both packet aggregation and scalable transport for more efficient backhaul of Ethernet, SONET/SDH, SAN and video services over OTN on a single platform."

"Our HyPHY platform solves the service convergence problem regardless of region or service mix," said Travis Karr, VP and general manager of PMC-Sierra's communication products division. "PMC-Sierra is investing to lead the transition to OTN and WDM with technology that enables cost-effective rollout of IP-services."

HyPHY 20G delivers high capacity framing, mapping and multiplexing of Carrier Ethernet, SAN, OTN, transparent bit services such as video and SONET/SDH to allow carriers to reduce the number of network elements, while incrementally adding bandwidth or changing service mix per node without forklift upgrades. The platform provides client-agnostic, rate-agile Small Form-Factor Pluggable (SFP) and 10Gbit pluggable (XFP or SFP+) interfaces and a set of flexible system interfaces for networking to a variety of switch fabric architectures. HyPHY 10G provides a lower density option for optical platforms. The HyPHY family integrates high-performance mixed-signal analog and media access control, along with other innovative features including:

??True per-port rate and protocol flexibility: Independent, rate-agile SERDES for direct connect to SFP, SFP+ and XFP optical modules, reducing cost, power and footprint;

??Multi-Service Muxponder: Single chip add-drop for both OTN and SONET/SDH;

??Efficient Fiber Utilization: First to market with integrated support for sub-ODU1 mapping of GE or other low speed client services; and

??Carrier Ethernet: First to market with integrated support for Timing over Packet (IEEE 1588 and SynchE) and Ethernet Link OAM required in mobile backhaul.

The PM5420 HyPHY 20G and PM5426 HyPHY 10G devices are sampling now to select customers in 40mm x 40mm 1517 ball FCBGA packages.
