Máy Phát Quang 1550nm FWT-1550ET

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, 50km 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's applicable for main links and distribution network links in large and middle CATV station head-end.

FEATURES:

◆ 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.
