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： The present invention converts each of the optical differential signals from DPSK demodulator from an optical signal into an electrical signal by using optical-electrical signal converters. Thereafter, each electrical signal is subjected to amplification adjustment at an appropriate amplification factor by variable amplifier, and an appropriate delay amount is added to each electrical signal by variable delay line, and thereafter data discrimination is performed by discriminator. Since two differential signals after DPSK demodulation are subjected to amplitude and delay adjustments, the need for optical parts is obviated enabling the use of electric circuits which can be integrated. Thus, the cost of the optical reception device will be reduced. Moreover, the since electric signals whose phases and amplitudes are equalized are inputted to discriminator, erroneous determination of data at discriminator will be reduced.

摘要： Transmission delay time measurement is performed on a signal propagation path between respective points of two printed circuit boards connected by a coaxial cable. Measurement is made of a frequency-domain response of the cable and a first time-domain response of the propagation path at its sending point and a second time-domain response of the propagation path at its receiving point. From the first time-domain response and the frequency-domain response, estimation is made of a third time-domain response of the propagation path that would be observed at the receiving point if there is no waveform distortion on the surface of the printed circuit boards. Time-domain correlation is calculated between the second and third time-domain responses. A first delay time is determined from the estimated time-domain response and a second delay time is determined from the correlation. The first and second delay times are summed to yield the transmission delay time of the propagation path.
