Summary: | A transceiver interface circuit, the circuit comprising an optical transceiver having a signal path configured to input at least one optical signal or output at least one optical signal; a compensation attenuator in the signal path configured to selectably attenuate the at least one optical signal; a memory comprising a first attenuation setting associated with a first optical cable and a second attenuation setting associated with a second optical cable; wherein the circuit is configured to receive an input indicating whether a switch is configured to a first state that passes the at least one optical signal via the first optical cable or configured to a second state that passes the at least one optical signal via the second optical cable; wherein the circuit is configured to load into the compensation attenuator either the first attenuation setting or the second attenuation signal in response to the input. |
