    FWT-1550ET series is a model of 1550nm Externally Modulated Optical Transmitter accordding with current international industry technique standard.The whole unit light source adopts narrow line width(Typ.=0.65MHz), low noise and continuous wave DFB laser,which is propitious to reduce the influence of dispersion.Adopting LiNbO3 external modulator that is especially designed by JDSU and FULLWELL original micro-wave technology , FWT-1550ET externally modulated optic transmitter can reach high index of CNR≥53dB,47~860 or 47~1080MHz,CTB≤-65dB, CSO≤-65dB,SBS:13~19dBm adjustable,50 km transmission.The whole unit is equipped with SNMP network management ,1+1 plug-in back-up power supply and casing temperature auto-control.

    FWT-1550ET can transmit whole band CATV signal.Ensuring excellent signal when at low frequency,it is applicable for main links and distribution network links in large and middle CATV station head-end.

     


     

     High performance: FULLWELL original Micro-wave Source Technology.Adopting RF pre-distortion technology , system get perfect CTB,CSO and SBS index when CNR≥53dB.

     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.
     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.
     Monitor the working state of modulator and laser.Working parameter shows on the LCD panel. 
     SNMP network management
     EMC、LVD and CE approved.
