Product Description

CATV 1550nm Top  External Modulated Optical Laser Transmitter

Product Description
EOT55XXT series is a model of 1550nm Externally Modulated Optical Transmitter according 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 original micro-wave technology , 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.
EOT55XXT series 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.
