Raman optical amplification system |
摘要 |
In a Raman optical amplification system in which WDM optical signals comprising two or more signal bands are transmitted in a transmission line, and in which a plurality of pumping lightwaves are introduced into said transmission line so that WDM optical signals in the shortest signal band are Raman-amplified by said plurality of pumping lightwaves, the interval between the longest pumping wavelength and the next-longest pumping wavelength differs by 0.2 to 1.4 THz in frequency. This makes it possible to flatten the level of the WDM signals by means of canceling the Raman gain ripple on the longer wavelength region of the distributed amplification.
