摘要： A receiving apparatus comprises a first waveform degradation compensating unit, a second waveform degradation compensating unit, a received waveform measuring unit for measuring waveform data on a received signal, a control unit for controlling compensation characteristics of the first and second waveform degradation compensating units to minimize a difference between frequency data obtained by converting the obtained received waveform data into a frequency domain and frequency data on a reference waveform free from waveform degradation, and time-constant generating units for making a difference in compensation characteristic control speed between the first and second waveform degradation compensating units. This realizes high-accuracy compensation for waveform degradation of a received signal stemming from chromatic dispersion, polarization mode dispersion or the like without employing a dispersion compensation fiber or a polarization maintaining fiber.

摘要： A power-saving mode flag generating unit 101e sets a power-saving mode flag to active (non power-saving mode, turning on the power-source) when it receives a reset signal from a MAC unit 102. Furthermore, the power-saving mode flag generating unit 101e sets the power-saving mode flag to sleep (power-saving mode, turning off the power source) in accordance with a signal-interrupt detection signal obtained by the signal-interrupt detecting unit 101f1 of the packet monitoring unit 101f. Depending on the state of a packet, the power-saving mode flag generating unit 101e changes the power-saving mode flag to active or sleep for the data communication area of the packet; however, for the ranging area of the packet, the power-saving mode flag generating unit 101e always sets the power-saving mode flag to active. A pattern discriminating unit 101g discriminates between the data communication area and the ranging area of the packet.

摘要： Using a switching signal from a coarse/fine switching and operation mode switching circuit, the width of change of a counter control value during power up is increased, and the width of change is reduced once a steady state is reached. In the steady state, the frequency of updating is limited by a control signal from an update permit control circuit. In the steady state, the frequency band of a current source in an LD driving circuit is reduced in width.
