BL-CATV-T series of Optical Transmitter is an important transmission equipment in the CATV Network and it converts RF signal to optical signal and supports maximum 20km transmission distance Instead of max 400m of Coaxial Cable. Based on high linearity, optical isolation, distributed feedback and Thermoelectric cooling DFB lasers, this transmitter is specifically designed for multi-channel TV signal Transmission with the built-in and reliable optical power output stabilization circuit and the laser Thermoelectric cooler temperature control circuit to ensure the best performance of the whole machine and the long life of the laser.
