Abstract
Systems and methods for remotely turning on and turning up a Raman amplifier are provided. In one embodiment, a method includes the step of turning on one or more Raman pumps of a Raman amplifier to a predetermined safe gain or power level. The method also includes determining an estimated loss along a fiber optic span of a link between adjacent nodes of an optical network. Responsive to the estimated loss being greater than a reach of an Optical Supervisory Channel (OSC) signal along the link, the method includes the step of adjusting the gain or power level of the one or more Raman pumps.
