WebOct 2, 2024 · The concept of stimulated Raman scattering (SRS) is used to explain the DWDM working principle. As a result, the amplified signal can be transmitted through fiber with little loss by using a special type of amplifier that collects light from the signal source. One of the key differences between an EDFA and a EDFAR amplifier is their gain. WebIt is also common to use a WDM coupler to add up two to three pump lasers with different center frequency. When using a different wavelength, pump power can be increased, and bandwidth is enlarged as well. By adjusting the ratio of these pump powers, Raman amplifier can achieve flat gain.
