PMC-Sierra Debuts OTN Access Solution Supporting Carrier Ethernet, SONET/SDH

PMC-Sierra introduced an innovative multi-service silicon solution that enables the convergence of high-bandwidth data, video and voice services over Optical Transport Network (ITU-T G.709 OTN) based metro infrastructures. To date, development of OTN, which is seen as the eventual replacement technology for SONET/SDH, has mainly focused on core applications. PMC-Sierra's new HyPHY Family aims to enable 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.

Specifically, PMC-Sierra's new 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 10 Gigabit 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 numerous 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.
