Abstract： |
The channel power equalization method of optical fibre Raman amplifier in wavelength division multplexing communication system relates to optical amplifier technology. It is characterized by that under the condition of that assuming that the Raman gain coefficient spectrum between pumping lights and signal lights is triangular form and the difference of transmission loss between signal lights and between different pumping lights can not be regarded between the power regulation quantity of input light of multi-wavelength pumping light and mean value of channel output power and grade a linear relation can be created, then according to the difference between the ouput power of FRA monitored by computer through optical power monitoring module and restrained object power the correspondent regulation quantity of every pumping lightpower can be calculated. |
