Product description

FWT-1550ET 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.

 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.
