4 way Optical Node TON6800Q

Overview        TON6800Q optical node can be used in CATV network, digital network and telecommunication network. The optical workstation is mainly designed for the transformation of CATV network. The RF input and output amplifier stages of the optical workstation are all made of high quality GaAs or silicon bipolar power amplifier module with high reliability, low power consumption, low noise, high output level and excellent performance / price ratio.

       The receiving power range of TON6800Q is 1dBm - 6dBm, and the output is up to 108dBuV; when 6dBm receiving power, the C/N is up to 46dB. 220V or 60V, the power supply mode is optional, and the high performance conversion circuit is turned into +24V and +5V DC power supply to the internal device of the optical node. Features         ● Structure design, flexible combination, widely used: independent reverse optical transmitter module, network management module, power module;
        ● The perfect surge suppression circuit improves the ability of resisting lightning strike and preventing surge impact;
        ● The input stage adopts imported low-noise GaAs amplifier, and the output stage adopts imported CATV high performance and high reliability module, which greatly improves the C/N and nonlinear distortion characteristics, and greatly reduces the power consumption of the whole machine;
        ● Strict reliability test, MTBF is more than 100 thousand hours;
        ● Optical AGC receive optical power -6dBm to +1dBm, output level change range + 1dB;
        ● RF output port level fixed adjustable, slope adjustable, output port 1-4;
        ● Each RF return is provided with a three state reverse noise suppressor and an insertion attenuator;
        ● Receive optical power digital tube display, display the received optical power;
        ● The RF level detection option can be selected, and the RF output signal level of the optical port port can be monitored in real time through the network management system. Open network management transponder options to meet GB network management standards. Technical Specifications
