    摘要： The invention relates to a method of activating an optical communication system comprising a plurality of optical amplifiers having an optical amplifier, between optical transmission lines in which wavelength-division multiplex optical signals are transmitted. The method comprises steps of: generating a desired slope in a desired wavelength range of a gain wavelength curve of the optical amplifier; adjusting an output of the optical amplifier to a desired output level; performing the above two steps in a plurality of optical repeater stations, the steps being carried out in sequence from the first to the last optical repeater stations; and adjusting a level in each optical signal in the wavelength-division multiplex optical signal so as to have substantially constant optical signal-to-noise ratios in the optical signals to be received. Activating the optical communication system according to this procedure allows proper execution of gain slope compensation, output control, and pre-emphasis control.

    摘要： A parallel-to-serial converter multiplexes parallel input data into a serial output data. This converter includes a multiplier for multiplying an input clock corresponding to a parallel input data, a divider for dividing the multiplied clock, and a waveform shaping circuit for shaping a serial output data by the multiplied clock. The converter multiplexes parallel data at a center of each phase thereof based on the divided clock by adjusting phases between the input data (or the input clock) and the divided clock to be in a predetermined relationship.
