A fiber optic transceiver includes both the fiber optic transmitter and receiver in a single component. The fiber optic transmitter converts an electronic signal into light signal and send this light signal in to the fiber optic core. On the other hand the receiver component accepts the light signal and convert it into electrical signal. Both the modules work independent of each other and the component work in both directions simultaneously.
