摘要： A Raman amplifier for use in an optical fiber communication system with dispersion compensation has a first order Raman pump source and a second order Raman pump source both coupled to the input ports of a four-port optical coupler having two input ports and two output ports. One output port is connected to an optical fiber length to inject a pump light signal into the fiber length for second-order Raman amplification and the other output port is connected to a dispersion compensating fiber.

摘要： An optical amplifier, or optical repeater, for amplifying wavelength division multiplexed (WDM) light A first demultiplexer demultiplexes the WDM light into first and second lights corresponding to different wavelengths in the WDM light. First and second optical amplifiers amplify the first and second lights, respectively. A first multiplexer multiplexes the amplified first and second lights into a multiplexed light. A dispersion compensator compensates for dispersion in the multiplexed light. A second demultiplexer demultiplexes the dispersion compensated, multiplexed light into the first and second lights. Third and fourth optical amplifiers amplify the demultiplexed first and second lights, respectively. A second multiplexer multiplexes the amplified first and second lights from the third and fourth optical amplifiers into a WDM light. The optical amplifier can be configured so that the first and second lights travel through the dispersion compensator in opposite directions.
