  • 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. 




     Flexibility: output optical power can be adjusted, rang from -3~-6dB. User need instruction when booking. The inside of FWA-1550H can integrate 1310/1490/1550nm EPON. GPON wave separator, convenient the PON network application vastly.

    High quality: adopt 980nm as a small signal to amplify in front, back adopt multimode 980nm large power pump laser, power is optimized reasonably by software, can most unlimited reduce NF of EDFA, it is comparable with EDFA. The feature can make system achieve excellent CNR.

    Reliability: the user is usually doubt about the high power output. In order to put customers at ease, our company divide whole unit, using three 1U rack instead a pc of 2U rack and hot backup. When there is no output in main machine, the space unit will work automatic.

     Intuitive: The laser is the most expensive machine components, machine equipped with microprocessor monitors the working state of the laser, the panel LCD window displays the operating parameters.

     Network type: Select All-piece status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standard, it enable network management monitoring capabilities.

     Plug in type power supply: adopt aluminium profile plug in type switch power supply, it can work at 85  265Vac City Network Voltage, As well as an optional DC48V power supply (reservations required); chassis cooling automatic temperature control.
