Product Description

Ordinary erbium doped fiber amplifier (EDFA) has advantages of low noise, high gain, wider bandwidth, high efficient pumping and stable operating, which is widely used in CATV system. However, along with the implement of fiber to the house (FTTH), system C/N will be worse significantly when EDFA uses as cascade amplification. Therefore, EDFA is required to produce high saturation output power and low distortion. After several years' research, high power ytterbium-erbium co-doped double-cladding fiber amplifier was developed to fit the requirement of FTTH and FTTB after conquer many technical difficulty. 
This serious product adopts JDSU, Lumics, etc multimode high power pump laser as pump source and American OFS closed beam splitter as double-cladding synthesizer. Built-in stable optical power circuit and laser thermoelectricity freezer guarantees best performance and long life cycle operating. Microprocessor software monitors operating status of laser which shows on LCD. Once operating parameter of laser deviate from the range of set value, microprocessor will cut power supply of laser automatically and red light turn will turn on with alarm (prompting fault cause on LCD).
