Accelerating packet and optical metro convergence

Internet infrastructure semiconductor solution provider, PMC-Sierra has announced the PM5422 META 20G device, designed to enable carrier Ethernet switch and router (CESR) equipment to connect to emerging metro optical transport networks (ITU-T G.709 OTN).

Carriers worldwide are transitioning their networks to OTN for optimised transport of IP services. According to PMC-Sierra, the META 20G enables a converged OTN infrastructure across IP and optical equipment, with unified end to end network management. The device integrates carrier Ethernet mapping and framing of 10GE LAN and WAN, and OTN mapping of IP-services such as storage area networks (SAN) and video protocols, while maintaining support for deployed technologies such as Packet over SONET/SDH (POS). The META 20G is the latest addition to PMC-Sierra's OTN product portfolio, which includes the HyPHY 20G and HyPHY 10G for packet optical transport platforms (P-OTP) and multi-service provisioning platforms (MSPP). The portfolio provides a chipset solution for end to end integration of OTN across metro networks. META 20G's concurrent framing and mapping of carrier Ethernet, OTN and SONET/SDH reduces line card variants and simplifies carrier supply chain operations. Its system side interfaces allow for integration onto new and existing line cards with direct connect to network processors and packet processing engines. It offers a range of capabilities, such as a support of optical modules, support for 10G LAN, WAN, SAN, Video and POS and Carrier Grade 10GE capabilities.
