Characteristics of Raman fiber amplifier:

No need for doped optical fibers - transmission fibers can be used as amplification fibers

Weak interaction - fiber length>10 km, high pump power>20-30 dBm

The wavelength range of signal amplification is related to the pump wavelength - suitable pump wavelength, any need

I need a magnifying tape!

Due to the gain generated along the transmission fiber, distributed Raman amplification can avoid signal attenuation

To improve the signal-to-noise ratio of transmitted signals at very low power levels (in low power water)

Flat, there is a lot of noise, and the quality of the optical signal deteriorates severely.

For distributed Raman fiber amplifiers, their noise index (-1dB) is much lower than the noise of EDFA

Index (5dB), thus reducing the total number of relay amplification stations and overall system complexity

Unified cost.
