Distributed Raman amplification does not require doped fibers, but utilizes the transmission fiber as an amplifying medium . The Raman process requires in general higher pump powers than needed
Distributed Raman Amplifiers: These amplifiers use the transmission fiber itself as the gain medium. They provide a more uniform gain distribution and can reduce the overall noise figure.

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).
Distributed Raman amplifiers utilize the optical fiber itself as the amplification medium. A high-power pump laser is injected at one end of the fiber, traveling backward to amplify the signal as it propagates.
We demonstrate different designs of distributed Raman amplifiers and propose the optimised configurations for both single and multi-fibre-span scenarios, which
