Abstract
Systems and methods for controlling a Raman amplifier by measuring power at one end of an optical fiber span. The Raman amplifier may include a laser that pumps an optical signal into the optical fiber span. The Raman amplifier may be connected to a controller that receives backscatter measurements. The controller may then adjust the Raman amplifier to maintain the backscatter substantially constant.
