1550nm DFB Laser Direct Modulation Transmitter

GWT3500 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 ensures the optimistic performance. GWT3500 is ideal for analog TV fiber distribution within 20Km and QAM TV signal long distance transmission within 100Km.

Features Low noise high linearity Ortel-Emcore cooled DFB laser GaAs Technology up to 862/1000MHz 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 Excellent pre-distortion technology improves CTB, CSO and C/N Built-in microprocessor accurately monitors laser output power and temperature.
