    摘要: An optical receiving apparatus is provided which is constructed to compensate for a rise in offset level attributable to low-frequency response of a light-receiving device. An offset detecting circuit detects a quantity of electricity indicative of an offset current quantity which corresponds to the zero level of an optical signal within the current quantity output from the light-receiving device, and a current subtracting circuit reproduces the offset current quantity based on the detected quantity of electricity, subtracts the reproduced offset current quantity from the current quantity output from the light-receiving device, and supplies the result to a preamplifier.

    摘要: A method for controlling power in a computer system having a network device and a wakeup function is disclosed. A determination is made whether or not the network device is in an associated state at the time when the computer system moves into a power saving mode. In response to a determination that the network device is not in the associated state, power supply is turned off from a power source to the network device. In response to a determination that the network device is in the associated state, power supply is continually provided from the power source to the network device.

    摘要: A dispersion compensating apparatus compensates dispersion of an optical signal using reflection-type etalons. Each of the etalons reflects the optical signal and at least one etalon has, with respect to a group delay characteristic, a wavelength cycle and a finesse that are larger than those of the other etalons. Power supplies and temperature control units respectively shift, in terms of the wavelength, the group delay characteristics of the etalons.

    摘要: A dispersion-slope compensator including a feedback-type optical filter constituted by a looped optical line; an input-and-output optical line which inputs and outputs optical signals; and optical couplers which couples the looped optical line and the input-and-output optical line at two or more positions so that a Mach-Zehnder interferometer is formed by a portion of the looped optical line and a portion of the input-and-output optical line which are located between two of the optical couplers. A portion of the optical path realizing an MZI arm which constitutes the Mach-Zehnder interferometer is spatially separated from the other portions of the optical path so that the optical length of the MZI arm can be variably adjusted, and an amount of compensation for dispersion slope can be variably set.
