Abstract:
An optical demultiplexer comprisingmeans for receiving an N channel multiplexed optical data signal, at a first data rate, formed from N signal data channels multiplexed together, the N signal data channels operating at a second data rate, where the first data rate is N times the second data rate, and where N is an integer >1 andN clocked receivers, each receiver including an edge-triggered electrical sampler circuit which uses a different phase-delayed electrical clock signal to trigger the receiver, the clock signal operating at the second data rate and having a pulse width duty cycle which is independent of the first data rate, said sampler operates in response to a rising or falling edge of the clock signal, each receiver receiving the multiplexed optical data signal and demultiplexing it into a different one of the N signal data channels of the multiplexed optical data signal.
