Abstract
An optical signal generation device in an optical communication system includes a control signal manager that outputs the number of information sequences and control signals, a timing manager that outputs a timing signal, signal multiplexers that generate multiplexed signal sequences by multiplexing in a time-division manner transmission information sequences and the control signals, pulse converters that convert the multiplexed signal sequences to pulse signal sequences, and transmission processing units that send transmission signal sequences whose intensities correspond to values of the pulse signal sequences. Each control signal includes an identification signal allowing each transmission information sequence to be identified, the timing signals change their values on a cycle of the minimum pulse width of the pulse signal sequences, and time positions at which values of the N timing signals vary are different from one another.
