摘要： In the optical communication device and the optical communication system using DPSK modulation whose cost is low, whose size is small and whose power consumption is low, the N:1 multiplexer 125 generates a serial signal by multiplexing a parallel signal coded by the DPSK modulation coding units 115˜117 bit by bit on a time division basis. The electric-phase modulation optical converter 127 converts a serial signal into a phase modulation light. The N-bit delay interferometer 132 executes DPSK decoding with respect to a phase modulation light by comparison with an N-bit preceding optical signal. The optical-electric signal converter 134 converts a decoded intensity modulation light into an electric signal. The N:1 demultiplexer 136 divides an electric signal converted by the optical-electric signal converter 134 into a number N of signals bit by bit on a time division basis.

摘要： A signal quality monitoring method with reliability is disclosed. After extracting a clock signal from the light signal, a decision region is set for each bit of the light signal. The decision region is defined by a plurality of threshold amplitudes corresponding respectively to threshold phases which are produced with respect to the clock signal. The quality of the light signal is monitored depending on whether an amplitude of the light signal falls into the decision region at timings of the N threshold phases.

摘要： An optical wavelength division coupler 11 wavelength-divides a wavelength multiplexed light to respective wavelength lights each of which is dropped to an optical gate switch 15-i (i=1˜n) and a light receiver 13-i by an optical coupler 12-i and supplied to an optical light fault monitor 14 through the light receiver 13-i. When the optical signal deterioration monitor 14 detects an optical loss of wavelength (OLOW), an optical loss of signal (OLOS) or an optical signal degrade (OSD) in wavelength lights processed by the optical coupler 12-i as a fault detection signal in an optical layer, a controller 19 controls the optical gate switch 15-i to cut off wavelength light passing therethrough and sends an optical alarm indication signal (AIS-O) to a downstream side. Therefore, when a loss of signal is detected by the light receiver 13-i, the optical signal deterioration monitor 14 can know the alarm indication signal (AIS) from the upstream side, removing the necessity of special hardware therefor.
