10G OTN framer/mapper/FEC

The Yahara S10123/S10124/S10126 is a 10G Framer/Mapper/PHY device for 10GbE/8G/ 10G Fibre Channel (LAN), OC-192/STM-64 (WIS/WAN), and OTU2 network applications. It is ideal for DWDM, Multi-Service Transport Platforms, and Metro-Ethernet Switch/ Routers. The highly integrated device supports pure 10GbE LAN Metro-Ethernet networks, as well as WAN and OTN networks via its rich suite of 10GbE over WAN and OTN mapping modes. With integrated 10G XFI interfaces on both the client and line side interfaces, an OIF compliant SFI-4.1 interface for either the client or line Interface, flexible SFI-4.2/SFI-5s/XAUI system interface, and provisional G.709 standard and enhanced FEC features, it provides a highly integrated solution with seamless interfaces to XFP, SFP+, and tunable laser MSA optical modules. Yahara is available in a 25x25 footprint (S10124), with all interfaces bonded out, as well as in two smaller 19x19 footprint packages. The S10123 device includes the serial 10G line interface and system interface bonded out, while the S10126 includes two serial 10G line interfaces bonded out.
