Hybrid Raman/Er-doped Fiber Amplifier

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 produced HFA***8Hybrid Raman/Er-doped Fiber Amplifier which transmit CATV extra long distance for the first time.Huatai HFA***8 is integrate FRA and EDFA rationally, can obtain flatter gain spectrum and higher OSNR. HFA***8 can prolong non-hop distance *0~*0Km and improve system CNR4.5~6dB. Product feature: Gain flatness Low noise ratio Optimized structure Main application: DWDM, CATV over-long main road optical transmission system Undersea optical transmission system
