ABSTRACT:
In an intercom system, electrical noise interference is alleviated by interconnecting the tranceivers and receivers with the control sets via fibre optic lines. Audio signals are applied to a multiplexer which drives an optical modulator. The output of the optical modulator feeds a fiber optic line. Conversely, optical signals are fed to an optical demodulator whose output feeds a demultiplexer. Audio outputs from the demultiplexers feed the receivers and tranceivers and control sets.
