Hi, I am using FS SFP28-25GSR transceiver module with Xilinx ZCU111 board. Xilinx GTY ibert test was tested using this transceiver module, and to run this test I used a 0dB insertion loss loopback cable. But this test failed. However, the same ibert test worked with a coaxial loopback cable. Can I get the register map to run this test using the SFP28-25GSR transceiver module?
