Abstract
A four-channel optical time division multiplexing scheme is presented which employs cascaded optical switches and operates on standard non-return-to-zero format optical data channels. Only low-frequency electrical drive signals at the clock speed of the input channels are required for the switches, and low-jitter output signals are obtained after a complete Mux-Demux operation.
