In fiber optic data links, the transmitter converts an electrical signal into an optical signal, which is coupled with a connector and transmitted through a fiber optic cable.

The light from the end of the cable is coupled to a receiver, where a detector converts the light back into an electrical signal. Either a light emitting diode (LED) or a laser diode is used as the light source.

How to Select Fiber Optic Transceivers

Fiber optic transceivers are designed for use with single mode or multi-mode cable. There are a number of different types of fiber optic transceivers available. They differ in the types of connections as well as in the quality of data transmission. Speed of transmission may also change from device to device. So it is necessary to choose the right Fiber Distribution Hub modules for your network.
