Xilinx has begun shipping its 100G IEEE 802.3bj Reed-Solomon FEC (RS-FEC) IP for data center, service provider, and enterprise applications.
The 100G RS-FEC LogiCORE IP solution seamlessly connects to Xilinx's integrated or soft 100G Ethernet MAC IP running on Virtex® UltraScale, enabling emerging optical solutions such as SR4, CWDM4, PSM4 or ER4f.
Xilinx is the first to demonstrate a complete 100G RS-FEC IP solution with Finisar and TE Connectivity (TE) optics showcased in multiple demonstrations at OFC 2015,
