PMC-Sierra Advances IP-over-OTN Architecture with META 20G
PMC-Sierra announced the latest step in its IP-over-OTN architecture with the unveiling of its PM5422 META 20G device. The META 20G devices enable Carrier Ethernet Switch and Router (CESR) equipment to seamlessly connect to emerging Metro Optical Transport Networks (ITU-T G.709 OTN) with unified end-to-end network management.
The The META 20G 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).
META 20G's concurrent framing and mapping of Carrier Ethernet, OTN and SONET/SDH reduces line card variants and simplifies carrier supply chain operations. Flexible system-side interfaces allow for seamless integration onto new and existing line cards with direct-connect to network processors and packet processing engines. Specific capabilities include:The META 20G is the latest addition to PMC-Sierra's OTN product portfolio. In July, PMC-Sierra introduced its HyPHY 20G and HyPHY 10G devices, which deliver high capacity framing, mapping and multiplexing of Carrier Ethernet, SAN, OTN, transparent bit services such as video, and SONET/SDH. These devices offer 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, while the HyPHY 20G is aimed at higher end platforms.
- Broad support of optical modules: Independent, rate-agile SERDES for direct-connect to 10G SFP+ and XFP modules for dense multi-port configurations;
- Any-Service over OTN: Support for 10G LAN, WAN, SAN, Video and POS;
- Carrier Grade 10GE capabilities: Integrated Timing over Packet (IEEE 1588 and SynchE) and Ethernet Link OAM required in latency sensitive applications such as mobile backhaul.
Target applications include Packet Optical Transport Platforms (P-OTP) such as Carrier Ethernet Switch Routers and Multi-Service Provisioning Platforms (MSPP).
