Abstract
An optical demultiplexer demultiplexes an N channel multiplexed optical data signal, at a first data rate, into N signal data channels. The demultiplexing is provided by N optical receivers, each receiver receiving a clock signal and the multiplexed optical data signal which is demultiplexed into a different one of the N signal data channels. In another embodiment, a shared photodetector converts the received multiplexed optical data signal into a multiplexed data signal which is then used by all of the N receivers.
