Design and Testing of an Analog Optical Communication Link Capable of the Simultaneous Transmission of Four Frequency Division Multiplexed Audio Signals

摘要

Communication Link featuring the analog transmission of four simultaneous Frequency Division Multiplexed audio signals, via optical means, was designed constructed, and experimentally tested. Low cost and common components were utilized throughout the system. Active filter techniques were employed and extended to uncommonly high frequencies. Fidelity of the recovered wave forms proved to be exceptionally high with crosstalk between channels of less than -50 dB.
