Raman-off gain 10dB FS-RFA Series Raman Amplifier
Erbium-doped fiber amplifier (EDFA), due to spontaneous emission (ASE) noise, as a result of numerous cascades, the accumulation of spontaneous emission noise, will greatly reduce the SNR of system receiver, thus limits the system capacity and non-relay distance. The new generation of Raman fiber amplifier (FS-1550) achieves the amplification of the optical signal by the optical gain generated by the Stimulated Raman scattering (SRS). FRA has a wide gain spectrum, the gain bandwidth can be further broadened by the use of multi-wavelength optical pump. After many years of research and network testing, our company develop and produce the series of FS-1550 Raman fiber amplifier, and introduce it to the ultra-long haul optical fiber CATV transmission, specifically in combination with the EDFA applications, the improvement of the indicators of the link is particularly evident, thus get more flat gain spectra and higher optical signal to noise ratio (OSNR).
This model is especially designed for no distance transmission.

Raman fiber amplifier can amplify the signal in the whole wavelength.with the repaid development of supper high-capacity system,the wavelength extend from C to L. And only EDFA can’t not meet the request of whole wavelength, and the RF can keep the flatness of gain and noise in 1526~1610nm through the choice and pump laser wavelength to improve the multiplex of fiber and the capacity of networks,but with very low noise figure.
