Catv Transmitter

These CATV Transmitter has the direct modulation laser of 1550nm DFB, used for analog TV, digital TV signals, the dense distribution of local fiber CMTS signal and long-distance optical fiber transmission of QAM TV signals. It uses high linearity DFB laser diode, the RF power digital automatic processing technology, and the development of pre-distortion circuit which developed by Greatway. The built-in microprocessors monitor emitter monitors the automatic working state and the best performance. OP3500 is DFB laser that used in analog TV which is distributed in long fiber of 20KM and QAM TV that is the signal transmission of 100 kilometers low noise and linearity. It can reach 862MHZ use GaAS technology.
a According to RF signal level and channel, RF power digital automatic processing technology automatically can control RF signal of RF driver, which can be sure that the best C/N, CTB&CSO, CTB, CSO&C/N, etc.
a Output power and the temperature is monitored by built-in microprocessor monitors accurately.The status parameter and function information is showed on the front panel VFD SNMP network management is optional.
