It consists in finding the laser pump configuration (power and wavelength) for a desired Raman gain spectral profile.
Some of the key benefits include: Wider gain bandwidth: Raman amplifiers can provide gain over a broader range of wavelengths, making them suitable for wavelength-division multiplexing (WDM)
The amplification occurs along the transmission fiber for the distributed Raman amplifier. The typical configuration is a backward pump scheme, as indicated in the Figure 15.4, which would introduce
