Product feature

1.  High performance: FULLWELL original Micro-wave Source Technology.

      Adopting RF pre-distortion technology ,system get perfect CTB,CSO and SBS index when CNR≥53dB.

2. Flexibility: The phase modulation Technology of the modulator boost the input optical power to the utmost,

    thus reaching long-distance transmission by ensuring excellent system CSO,SBS 13~19dBm adjustable,

    AGC/MGC mode is optional at spot,OMI can be optimized at spot.Suitable for various network.3. Reliability: 19"1U standard rack,1+1 plug-in back-up power supply,which can work at 86~265voltage,

    MS switch automatically,casing temperature auto-control.4. Monitor the working state of modulator and laser.Working parameter shows on the LCD panel. 5. SNMP network management6. EMC,LVD and CE approved.

Main application

1,   Can be used in long-distance main links and distribution network links in large and middle CATV station head-end.

       Analogue digital hybrid transmission>200Km(with dispersion compensation).2,   Applicable to the value-added service of DWDM fiber optic CATV system and CFG dispersion compensation system.3,   Can be used in branch FTTH that has high system index demand.Point to point>65Km,CSO≤-65dB.4,   Can be used in second-grade service area of sub-station,providing second-grade users with high quality

      and high reliability value added service such as RFTV, IPTV, VOD and so on.
