Product Description

Product description: Erbium-doped optical fiber amplifier (EDFA), because of the ASE and the accumulation of spontaneous radiation noise, which cuts down on the Signal-to-Noise, after many cascade connections, limits the transmission volume and the non-transceiver distance. A new generation Optical Fibre Raman Amplifier (FRA) utilizes the light gain in the stimulated Raman scattering (SRS) in the optical fiber and realizes the amplification of the signal light. FRA, having a very low equivalent noise and a wide gain scope, which can further widen the gain bandwidth, represents the new optical fiber amplifier development direction. Huatai DRA***8 separates optical fiber Raman Amplifier. It adopts built-in negative dispersion DCF as gain medium. In the system, it can realise the concentration amplification of the optical signal. It's especially suitable for the super-long optical fibre main road, which needs to compensate the dispersion. Product feature: Gain flatness Low noise ratio High dispersion compensation Main application: DWDM, CATV over-long main road optical transmission system Undersea optical transmission system
