摘要
An optical fiber amplifier having constant output power for each channel including a first measuring unit for dividing an input light signal into a first light signal and a second light signal, sub-dividing the first light signal into a plurality of light signals and converting the plurality of light signals into electrical signals to output the electrical signals, an optical fiber amplifying unit for amplifying the second light signal according to a predetermined amplification control value, a second measuring unit for converting a light signal of a predetermined wavelength band, output from the optical fiber amplifying unit, into an electrical signal, and an output power controller for controlling the predetermined amplification control value according to a plurality of output values of the first measuring unit and an output value of the second measuring unit, so that the power level of the optical fiber amplifying unit is maintained at a constant level.
