GWT3300 Signal Long-distance Fiber Transmission1310m DFB Transmitter

          GWT3300 series 1310nm transmitter is primarily used for TV video signal, digital TV signal, telephone voice signal and data 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. 

1)  Low noise high linearity Ortel-Emcore DFB laser
2)  GaAs Technology up to 1000MHz (typical 862MHz)
3)  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
4)  Excellent pre-distortion technology improves CTB, CSO and C/N
5)  Built-in microprocessor accurately monitor laser output power and temperature.
6)  Front panel VFD displays the status parameters and function message
7)  19″1U standard rack with RS485 and RS232 ports for remote monitor and control
8)  SNMP network management optional
9)  RoHS compatible

Test condition：Input 77 channels NTSC signal to the optical transmitter and measure the standard optical receiver C/CTB, C/CSO and C/N in conditions of -1dBm optical input (10km fiber + optical attenuator) and 36 dBmV RF output
