CATV Separate Raman Amplifier
RFA4000
-
Hangzhou Huatai Optic Tech. Co., Ltd.
1. Erbium-doped Fiber Amplifier, due to the multiple cascades and the accumulation of noise caused by spontaneous emission, will reduce the system CNR greatly and thus it will limit the transmission capacity and distance of the system. Raman Amplifier is a newly designed fiber amplifier based on Stimulated Raman Scattering (SRS) effect. Raman amplifier is considered as the core technology of new generation DWDM fiber over-long communication. Compared with Erbium-Doped Fiber Amplifier, Raman amplifier has the advantage of low Noise Figure (NF), wider gain bandwidth, flexible gain spectral region and stable temperature. It is the only device that can operate in 1300~1600 nm.

With SAT-IF input EDFA
HA4600/IF
-
Hangzhou Huatai Optic Tech. Co., Ltd.
Huatai HA4600/IF series, is narrow-band multiplexing EDFA suitable for L-Band fiber link application. With build-in 1550nm Internal Modulation SAT-IF optical transmitter, used for inter-cutting DBS. The WDM inside will multiply the signal from TX and main line signal that is inputted from outside, then the combined signal will enter EDFA to be amplified to serve the local subscribers. To avoid the interferes caused by mismatching of the optical output power between TX and main line signal from outside, output power of the TX can go through a VOA, thus, it can be adjusted or set from the front panel. This unit is simple and clear, easy to be installed and tested. It offers a high quality and cost-effective solution for inter-cutting DBS into full optic relay 1550nm fiber CATV system and second-stage service area.
