PMC-Sierra offers OTN-centric multi-service convergence devices for metro apps

JULY 20, 2009 -- PMC-Sierra Inc. has introduced the PM5420 HyPHY 20G and PM5426 HyPHY 10G devices, which are designed to enable the convergence of high-bandwidth data, video, and voice services over Optical Transport Network (ITU-T G.709 OTN) based metro infrastructures.

The devices are designed to meet the need for low-power, cost-effective service gateways with simultaneous protocol support for Carrier Ethernet, video, SAN, OTN, and SONET/SDH at the network edge. PMC-Sierra says its HyPHY products can reduce line card variants by 75 percent, achieve 50 percent power savings, and deliver multi-service aggregation flexibility to accelerate the transition to IP-optimized OTN networks.

The devices are targeted at such applications as reconfigurable optical add/drop multiplexers (ROADMs), packet optical transport platform (OTP), and micro OTP equipment that address 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, vice president 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."

HyPHY 20G is designed to deliver high-capacity framing, mapping, and multiplexing of Carrier Ethernet, SAN, OTN, transparent bit services such as video, and SONET/SDH to allow cCarriers 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 10-Gbps 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 features that PMC-Sierra asserts include:

• 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.
