How to test an Ethernet optical module

Insert a loopback module (electrical or optical) or loop a short fiber from Tx to Rx on the same port / device and test link negotiation or run a ping/traffic test. For optical, a dedicated loopback cable or LC loop will do. What you do Check the port/link LEDs on the switch. In fiber optic networks, optical transceivers such as SFP, SFP+, QSFP28, and QSF...
