World’s first implementation of a “flexible transport” using flexible Ethernet (FlexE) in the FPGA as a client to the variable rate line optics. The demo showcases Xilinx’s FlexE solution featuring the Xilinx Virtex® UltraScale™ VU190 device with FlexE IP connected to the Acacia AC400-U coherent transponder module supporting flexible transmission rates with up to 400Gb/s capacity. The combined set up demonstrates next generation transport which allows for maximization of optical link budget on long haul and data center interconnect links. Xilinx FlexE IP is available now for early access.
