Field: Optics (Instruments)
Classification: CPC H | IPC H

Claim 0:
1. A self-adaptive wave band amplification method, characterized in comprising:
a light splitting step for detecting C band detection light and L band detection light in an in-band signal; and
a scheduling step for enabling a slave Raman amplifying unit to participate in amplification after the L band detection light is detected,
wherein the method further comprises a wave combining step for performing a wave combination/splitting by using two optical wavelength division multiplexers after the slave Raman unit injects its pumping light into a master Raman unit, the wave combination comprising:
injecting pump light from the master Raman amplifying unit into a transmission fiber after wave combining/splitting once, and injecting pump light from the slave Raman unit into the transmission fiber after wave combining/splitting twice; or
injecting the pump light from the slave Raman unit into the transmission fiber after wave combining/splitting once, and injecting the pump light from the master Raman unit into the transmission fiber after wave combining/splitting twice; or
performing a first wave combination for the pump light from the master and slave Raman units and then a second wave combination/split with signal light.
