Distributed Fiber Raman Amplifier

Optical fiber Raman amplifier is used to provide gain for optical signal by using Raman effect in quartz fiber, and realize high gain and low noise amplification for optical signal in C or L band, which can effectively compensate the attenuation of optical signal in long-distance optical fiber transmission. It is usually used in long-distance optical transmission system, distributed optical fiber sensing, and dense wavelength division multiplexing optical transmission system.

Features:

² Wide wavelength range

² High gain coefficient

² Low noise index

Application：

² Long distance optical communication network

² Optical fiber distributed sensing

² Fiber laser
