Raman Amplifiers in Telecommunications Networks
A Raman amplifier system includes high-power pump lasers (often diode lasers around 1450–1490 nm for C-band signals), wavelength combiners (couplers or circulators), and fiber spans

Raman Amplifier
The Raman amplifier is a distributed amplifier. It can be used at both the transmit end (for forward amplification) and the receive end (for backward amplification).

Raman Amplifier
In some applications, such as when a large span or extra-wide bandwidth is required, the Raman amplifier is the only one that can be used. This amplifier requires much higher power than the EDFA.
