摘要： A wavelength division multiplexed (WDM) optical signal amplifier which amplifies optical signals having different wavelengths with minimized deviations in their respective output power levels, while maintaining the total optical output at a constant power level. An optical splitter, disposed at the output of the amplifier, splits off a fraction of the amplified WDM optical output signal for feedback purposes. This WDM optical feedback signal is subjected to a wavelength division demultiplexer, where the optical components contained in the signal are demultiplexed into separate optical feedback signals each having a different wavelength. A plurality of optical power level detectors detect the optical power levels of the individual optical feedback signals. Based on the detected optical power levels, a controller adjusts the individual output power levels of the plurality of electrical-to-optical converters, so that the optical power levels detected by the optical power level detectors will coincide with each other.

摘要： An optical amplifying module having an internal pumping source is provided. WDM signal light obtained by wavelength division multiplexing a plurality of optical signals allocated to different wavelength channels is supplied to the optical amplifying module. An output power from the internal pumping source is adjusted so that the optical amplifying module provides a gain for the WDM signal light. A booster module having an external pumping source for supporting the gain is connected to the optical amplifying module. An output power from the external pumping source is set according to the number of channels of the WDM signal light. This method allows easy response to a change in the number of channels of the WDM signal light.
