Method and system for optical fiber transmission using Raman amplification |
摘要 |
A variable optical attenuator for attenuating the signal light is provided in an optical fiber transmission line for transmission of signal light while performing Raman amplification, and the attenuation of the variable optical attenuator is adjusted based on the optical power detected at the reception terminal of the optical fiber transmission line.
