Product Description

Product Description: Er-doped EDFA, can greatly reduce system SNR in receiving terminal, due to ASE noise' s influence, through many times connection, the accumulation of ASE noise, thereby limiting the transmission capacity of system and hop-less distance. A new generation of FRA can amplify signal light through utilizing SRS brings about light gain. FRA has wider gain spectrum, can through adopt multi-wavelength optical pump broaden the gain bandwidth. After several years research and network test. Huatai FRA***8 is a Separate optical fiber Raman Amplifier. In the system, it adopts reversing pump, the gain medium utilizes the optical fiber in the transmission cable and amplifies the signal light during the transmission, realizing the long-distance non-transceiver transmission and long-distance pumping. It is especially suitable for the situation that is inconvenient to establish relay station (for instance, undersea cable and so forth). Product feature : Gain flatness Low noise ratio Optimized structure Main application: DWDM, CATV over-long main road optical transmission system Undersea optical transmission system
