Do single-fiber optical modules have A-end and B-end

Single fiber SFPs are always deployed in matched pairs, sometimes referred to as “A-end” and “B-end” modules. These paired modules use complementary wavelengths. For instance, if the local SFP transmits at 1310nm and receives at 1550nm, the remote SFP must transmit at 1550nm and. A fiber-optic link can function only if Tx on one end is connected to Rx on...
