GWT3300 Series 1310nm 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.
Features
l Low noise high linearity Ortel-Emcore cooled DFB laser
l GaAs Technology up to 1000MHz (typical 862MHz)
l 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
l Excellentpre-distortion technology improves CTB, CSO and C/N
l Built-in microprocessor accurately monitor laser output power and temperature.
l Front panelVFD displays the status parameters and function message
l 19″1U standard rack with RS485 and RS232 ports for remote monitor and control
l SNMP network management optional
l RoHS compatible
