A short-range transceiver (SR) is designed to transmit data over a short distance (up to 300 m). A Long-Range transceiver (LR) is designed to transmit data over long distances (up to 10 km). Copper Transceiver (CR), unlike SR and LR, uses a copper cable, and the distance covered depends on the type (10-30m or 80-100m).
On FortiGate-3501F/2601F for instance, the LR4 or SR4 media type will not be visible on the port configuration if the port speed is set as auto, only CR is available/visible. To see LR4, SR4 and CR4 media type, the port speed needs to be set to 100Gfull.
