The specification discloses a transmitter and receiver set which operates so as to: pick up digital information as electrical impulses, such as information produced by a computer; translate this information into square-wave optical signals, which may be carried along optical fiber; amplify the electronic signal, as well as impress on the electronic signal an oscillation which is characteristic of the data signal alone; detect the said oscillations; and translate this detected signal into the standard electronic signal output.
