2x10G OTN framer/mapper/FEC

The S20101 is a 2-port Metro Ethernet and Wide-Area Network access device aimed at CarrierGrade Ethernet Switch/Routers and Dense Wave Development Multiplexor applications. The device supports both XAUI and RXAUI system/backplane interfaces and 10Gb/s High Speed Serial Line Interfaces for seamless connection to XFP/SFP+. Via its rich suite of mapping modes, the PQ20E device can provisionally map 10GbE into OTN and WIS Compliant signals to be transported over multivendor OTN, WIS (SONET/SDH) networks. In addition, the device also supports OTN and WIS bypass modes to enable pure LAN PHY applications.
