摘要： A data modulator unit generates a DQPSK optical signal in accordance with a data signal. A phase shift unit provides a phase difference of π/2 between a pair of arms. A photodetector converts an output signal of the data modulator unit into an electrical signal. A filter is a low-pass filter with a cut-off frequency lower than a symbol frequency, and filters an output signal of the photodetector. A monitor unit detects power of an output signal of the filter. A phase difference control unit adjusts the amount of phase shift in the phase shift unit so as to minimize power of an output signal of the filter.

摘要： A phase shift unit provides a prescribed phase difference (π/2, for example) between a pair of optical signals transmitted via a pair of arms constituting a data modulation unit. A low-frequency signal f0 is superimposed on one of the optical signals. A signal of which phase is shifted by π/2 from the low-frequency signal f0 is superimposed on the other optical signal. A pair of the optical signals is coupled, and a part of which is converted into an electrical signal by a photodiode. 2f0 component contained in the electrical signal is extracted. Bias voltage provided to the phase shift unit is controlled by feedback control so that the 2f0 component becomes the minimum.

摘要： In the WDM optical transmission system, a high-slope dispersion compensator compensates wavelength dispersion produced in the optical transmission line. The high-slope dispersion compensator has a dispersion slope characteristic, by which a dispersion slope is substantially compensated over the wavelength bandwidth of the optical transmission line, and also a dispersion compensation characteristic, by which the residual dispersion produced after compensating the dispersion slope using the above dispersion slope characteristic becomes symmetrical with respect to a wavelength in the vicinity of the center of the wavelength bandwidth. To achieve the above compensation, a wavelength-multiplexed signal is divided into wavelength bandwidth groups, and the residual dispersion of the optical transmission line is compensated on a group-by-group basis for the wavelength bandwidth groups.

摘要： The present invention provides a wavelength division multiplexing transmission system for separating wavelength division multiplexing signals, where signal lights with different bit rates are wavelength division multiplexed, according to the bit rate, and processing the separated signals individually. The wavelength division multiplexed signals, where a low-speed bit rate signal is disposed in an odd channel group and a high-speed bit rate signal is disposed in an even channel group, are demultiplexed into a low-speed signal group and a high-speed signal group by an unequal bandwidth interleaver. The low-speed signal group is processed (e.g. demultiplexing, dispersion compensation) by an optical device appropriate for the low-speed signals, and the high-speed signal group is processed by an optical device appropriate for the high-speed signals. By this, a relatively expensive and high function optical device can be applied only for the high-speed signal side, so an increase in the device cost can be kept down. Also a device with specifications appropriate for each signal can be used.
