摘要： Disclosed is a wavelength-division multiplexing optical transmission system in which an optical lossy medium, optical amplifiers and Raman amplifiers for compensating for loss in the optical lossy medium are cascade-connected. The system includes power-level equalizing means for equalizing optical power levels input to an optical amplifier of a succeeding stage by adjusting excitation ratio of a Raman amplifier; optical-SNR equalizing means for adjusting power levels at a transmitting end to equalize optical SNRs at a receiving end; and correction-value acquisition means for acquiring a correction value that represents an amount of change in power of each wavelength before and after optical-SNR equalization control. At control for equalizing power levels by a Raman amplifier, the power-level equalizing means performs equalization control using the correction value that represents the amount of change in power of each wavelength before and after optical-SNR equalization control the previous time, and the optical-SNR equalizing means subsequently performs optical-SNR equalization control.

摘要： A wavelength-division multiplexing optical communication system for wavelength-division multiplexing a plurality of optical signals having different wavelengths and transmitting a wavelength-division multiplexed signal via an optical fiber transmission line. The wavelength-division multiplexing system includes a multiplexing unit that wavelength-multiplexes a plurality of optical signals having different wavelengths. A storing unit stores information regarding an addition or subtraction of an optical signal to be wavelength-multiplexed, into a predetermined time slot of a frame signal that is composed of a plurality of time slots. The wavelength-division multiplexing system outputs a monitor/control frame signal, based upon the stored information. A transmitting device transmits the monitor/control signal as an optical signal having a wavelength different from the wavelengths of the multiplexed optical signals.

摘要： An optical transmission device has an optical amplifier, first and second control signal reception units and a transmission unit. The first control signal reception unit receives control signals from a receiving end optical service channel. The second control signal reception unit receives control signals from an operator. The transmission unit transmits to the optical amplifier, either the control signals from the receiving end optical service channel or the control signals from the operator so that the optical amplifier operates in either an automatic level control mode or an automatic gain control mode.
