Claim 2:
3. The self-adaptive wave band amplification method of claim 1, characterized in that a work flow of a Raman amplifying unit includes following steps:
step a, determining whether a pump-starting condition is met, and executing step b if yes;
step b, turning on a Raman unit pump with a preset small optical power value; returning to step 4,1-a when it is determined that the pump-starting condition is not met or executing step c when it is determined that a reflection coefficient does not exceed a threshold;
step c, configuring pump power according to a comparison between light power of each band in signal light and a corresponding threshold, and returning to step a when it is determined that the pump-starting condition is not met, and executing step b when it is determined that the reflection coefficient exceeds the threshold.
