Description

technical field [0001] The present invention relates to dense wavelength division multiplexing (DWDM) optical communication equipment in the field of optical communication, in particular, to an adjustment device and method for the average slope of the gain spectrum of a Raman (Raman) amplifier. Background technique [0002] In dense wavelength division multiplexing systems, in order to extend the transmission distance, optical amplifier devices are used, one of which is a Raman amplifier, which feeds high-power pump light into the optical fiber and utilizes the stimulated Raman scattering effect in the optical fiber (SRS effect), so that the energy of the pump light is transferred to the signal light longer than its wavelength, and the amplification of the signal light is realized. The Raman amplifier has a wide range of action and is more suitable for wavelength division multiplexing optical transmission systems. Selecting the appropriate pump wavelength can make the best ...
