Does Ethernet 1000BASE-X or SGMII work for 100base-fx network ?
I am going to use my Virtex6-LTX to communicate with a device with 100base-fx port . Is it possible to use Xilinx's Ethernet 1000BASE-X or SGMII solution to connect to a 100base-fx port ? ( I prefer the FPGA's internal transceiver and a external SFP module. However , I am not sure if the IP work for a network without 1000base-x ports )
