Susumu Kinoshita, Yasushi Sugaya: Optical amplifier for amplifying a wavelength division multiplexed (WDM) light including light in different wavelength bands. Fujitsu, Staas & Halsey, September 13, 2005: US06943940 (4 worldwide citation)

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 sec ...
