In communications systems having optical networks, data rates in the electrical domain can be matched to data rates in the optical domain by means of time-division multiplexing, with the pulses forming the transmitted optical data being compressed. A method performs the necessary pulse decompression on reception in all-optical manner. The method includes forming q auxiliary signals respectively obtained by amplitude modulating each of q optical carrier waves having different wavelengths by the received signal, and superposing q delayed auxiliary signals obtained by applying delays to the auxiliary signals such that any two consecutive delayed auxiliary signals are offset in time by the duration of the pulses making up the received signal.
A method of decompressing pulses making up a received binary optical signal, said pulses being contained in successive signal bit times T of said signal, said pulses having a pulse duration Δ not greater than T/q, where q is an integer number not less than 2, said method comprising:
Apparatus for decompressing pulses making up a received binary optical signal, said pulses being contained in successive signal bit times T of said signal, said pulses having a pulse duration Δ not greater than T/q, where q is an integer number not less than 2, said apparatus comprising:
