Fiber Raman amplifier utilizes the Raman scattering effect in quartz optical fibers to provide gain for optical signals. By employing a 14xxnm wavelength laser as the Raman pump, it can provide gain for the signal light in the C-band, effectively compensating for the attenuation of optical signals during long-haul transmission in optical fibers. It is suitable for long-distance optical transmission systems and distributed optical fiber sensing systems.

*Note 1: This amplifier serves solely as a Raman amplifier pump and requires the cooperation with optical fibers in the user's system to generate Raman gain. It is not a standalone Discrete Raman Amplifier. It is generally recommended to deploy a distributed Raman amplifier when the optical fiber length in the transmission system exceeds 50km.
*Note 2: The gain of a distributed Raman amplifier refers to the comparison of signal power at the system's receiving end when the Raman amplifier pump is turned on and off, also known as On-Off Gain. This On-Off Gain differs from the amplifier gain in the conventional sense, which is not the ratio of output power to input power. The actual effects (Raman gain coefficient, gain flatness) of a distributed Raman amplifier are closely related to various factors such as the type of transmission fiber, fiber length, signal wavelength, and power. The typical values provided here are for reference only.
