PMC-Sierra has unveiled its PM5422 META 20G device, which enables carrier Ethernet switch and router equipment to seamlessly connect to emerging metro optical transport networks (ITU-T G.709 OTN).
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 wide area network, and OTN mapping of IP-services such as storage area networks and video protocols, while maintaining support for deployed technologies such as Packet over Sonet/SDH.
META 20G’s concurrent framing and mapping of carrier Ethernet, OTN and Sonet/SDH reduces line card variants, and simplifies carrier supply chain operations.
