Uses pulse-rate modulation system with center frequency of 50 kHz. Audio fed into transmitter varies pulse rate, for driving LED coupled to optical fiber. Phototransistor at other end of fiber receives and demodulates light signal for reconstruction of audio.-I. Math, Math's Notes, Ca July 1977, p 67-68 and 90.
