First-order fiber Raman amplifier

Fiber Raman amplifier uses the Raman scattering effect in quartz optical fiber to provide gain for optical signals. It uses 14xxnm wavelength laser as Raman pump to provide gain for C-band signal light, which can effectively compensate for the attenuation of optical signals in long-distance optical fiber transmission. It is suitable for long-distance optical transmission systems and distributed optical fiber sensing systems.

Product features：Wide wavelength range、 High gain factor、 Low noise figure

Application area：Long distance fiber communication、 Fiber-optic distributed sensing、 Fiber laser
