ABSTRACT:
A clock extracting apparatus arranges bit intervals of a signal light train incident on a signal light processing section to have uneven periods, makes bit intervals between a predetermined signal light and signal lights adjacent to the predetermined signal light to be longer than a switching time of an electro-optical gate, selectively demultiplexes the predetermined signal light using the electro-optical gate, and extracts a clock synchronized with the signal light train from the demultiplexed signal light. Thus, it becomes possible to extract a clock synchronized with an ultra-high speed from a signal light train.
