Abstract
An optical receiver able to distinguish a failure occurred in one of multiplexed signals from a failure in the transmission medium is disclosed. The optical receiver includes an optical de-multiplexer, optical devices, a signal processor, and a controller. Each of the optical devices converts the de-multiplexed signal into an electrical signal. A clock is extracted from one of the electrical signals. The processor decides, based on the electrical signals and the clock, one of the multiplexed signals falls in a failure.
