Abstract
Raman fiber amplifiers are provided in which multiple pump wavelengths are used. A Raman fiber amplifier may be used to amplify optical signal channels over a range of wavelengths. Some of the pump wavelengths may be selected to create Raman gain in this range. Other pump wavelengths may be selected to create Raman loss in this range. Different pump powers may be used at each pump wavelength.
