3R REGENERATOR FOR FULLY OPTICAL TIME DIVISION MULTIPLEX SYSTEMS Russian patent published in 2012 - IPC H04J3/00 

FIELD: information technology.

SUBSTANCE: invention relates to multichannel communication and can be used for 3R regeneration of a linear signal in fully optical multichannel time division multiplex systems. The apparatus has a directional coupler, a semiconductor optical amplifier, an optical switch, a clock signal source, an attenuator and a semiconductor amplifier, an insulator, an optical filter with wavelength 1555 nm, an amplifier for signal reconstruction based on amplitude in form of an erbium fibre-optic amplifier. The optical switch used is a terahertz optical asymmetric demultiplexer. The clock signal source has a terahertz optical asymmetric demultiplexer and a distributed-feedback laser, an insulator, an optical filter with wavelength 1562 nm, an attenuator and a semiconductor amplifier, a self-pulsed laser, a distributed-feedback laser and an electroabsorption modulator, a photodiode, two directional couplers and delay lines for multiplying clock pulse frequency.

EFFECT: faster operation of the device.
