Abstract
A light source package is disclosed for a Raman amplifier node having a primary optical fiber for carrying an optical signal and a secondary optical fiber for carrying the optical signal when the signal is rerouted from the primary optical fiber. The light source package includes a primary light source for emitting light into the primary optical fiber when the optical signal is carried by the primary optical fiber to induce Raman gain of the optical signal, and a secondary light source for emitting light into the secondary optical fiber when the optical signal is carried by the secondary optical fiber to induce Raman gain of the optical signal.
