Product Overview

Description

1550nm CATV Externally Modulated Optical Transmitter 

 

 

 

  

 

 

  

CWT3500 is a direct modulation 1550nm DFB transmitter for analog TV, digital TV and CMTS signals local fiber dense distribution and QAM TV Signal long-distance fiber transmission. The transmitter utilizes high linearity DFB laser, RF power digital automatic process technique, along with RF pre-distortion circuit developed by Greatway Technology. The built-in microprocessor monitors the transmitter working status and automatically insures the optimistic performance. CWT3500 is ideal for analog TV fiber distribution within 20Km and QAM TV signal long distance transmission within 100Km.

Functional Features

Low noise high linearity Ortel-Emcore cooled DFB laser

GaAs Technology up to 862MHz

 

RF power digital automatic process technology control the laser driving RF power level automatically according to RF signal level and channels, ensuring the best C/N, CTB and CSO
