Optical amplification apparatus and optical transmission system |
摘要 |
An optical amplification apparatus estimates a gain deviation over a range of multiplex wavelength of a signal light received from an EDFA in the preceding stage, selects a gain profile, with which the gain deviation becomes a minimum, from a gain profile storage section, and determines the gain profile. This optical amplification apparatus further controls an HPU (High power pumping light source) according to the determined gain profile and performs Raman amplification on the received signal light.
