Fiber Raman amplifier utilizes the Raman scattering effect in quartz fiber to provide gain to optical signals. Using a 14xxnm wavelength laser as a Raman pump to provide gain for C-band signal light can effectively compensate for the attenuation of optical signals during long-distance fiber transmission. Suitable for long-distance optical transmission systems and distributed fiber optic sensing systems.
Application scenarios: Long distance fiber optic communication, fiber optic distributed sensing, fiber laser
