EDFA has advantages of low noise, high gain, wide bandwidth, efficient pump and stable working condition, etc. It is used on CATV system widely. When the EDFA is used to cascaded amplification in the CATV system, the C/N deterioration is serious. In the face of this kind of situation, a international new double-clad fiber has been developed. It takes advantage of envelope pump technology, which overcomes shortcomings of the single-mode fiber, and makes output power increased one to two orders of magnitude, and promotes the development of high-power fiber amplifier. The factory overcomes multiple technical difficulties, and then developing erbium ytterbium co-doped double-clad fiber amplifier which is fit to CATV system to adapt current require of FTTH and FTTB.
