Supports 4 Channels of Framing

In additional to FlexO-1/2/4-SR function, the Core supports up to 4 channels of OTU25/50-RS framing. For OTU25/50-RS and FlexO-1-SR, the Core also supports legacy FEC RS(528, 514). The north-bound interface from the multi-channel OTUC/ OTUw client interface provides a configurable system interface. The southbound interface is mapped (at the PMA layer) to the on-chip SERDES. The core is responsible for channel alignment and FEC (where applicable).

Benefits

  • Combines Ethernet streams at a variety of rates to a single multi-channel interface at the OTUCn/OTU25/50 client
  • The Core allows access connections supporting OTU25-RS, OTU50-RS, FlexO-1-SR, FlexO-2-SR and FlexO-4-SR in any combination on any port or groups of ports to a maximum total bandwidth of 400Gbps
  • Dynamically change rate on any port without affecting existing traffic
  • Off-the-shelf, proven technology implementation in ASIC SOC
  • Tested and interoperability-proven
