Abstract
An optical multiplexer cyclically samples a plurality (N) of optical input signals, each derived from an electrical input signal, at a frequency rate which equals or exceeds the Nyquist rate of each electrical input signal. A demultiplexer demultiplexes a received multiplexed optical signal into N optical signal sample streams which are then converted into the original N electrical input signals using the low-pass electrical frequency filter characteristics of the optical detectors and electrical circuits which connect to the N demultiplexer outputs.
