Product Description

 

Product Description

Erbium-doped optical fiber amplifier (EDFA), because of the ASE and the accumulation of spontaneous radiation noise caused by many cascade connections, will reduce the Signal Noise Ratio (SNR) greatly in system receiving end and thus limit the transmission volume and the non-transceiver distance. Raman Fiber Amplifier (RFA) utilizes the optic gain in the Stimulated Raman Scattering (SRS) in the optical fiber and realizes the amplification of the signal optic. FRA, with very low equivalent noise and a wide gain scope, can further widen the gain bandwidth by adopting multi-wavelength optical bump, which represents the development direction of the new optical fiber amplifier. DRA5228/F is a separated optical fiber Raman Amplifier. It adopts built-in negative dispersion DCF as gain medium. In the system, it can realize the concentration amplification of the optical signal. It's especially suitable for over-long trunk that needs high dispersion compensation.
