TON6800W Optical Node

Overview    TON6800W optical node can use in the CATV network, digital network and telecommunication network. This optical node aims at each cable TV network modification requirement. The optical node’s RF input、output amplifier stage all adopt high quality GaAs or silicon double pole power multiplication amplifier module, high reliable, low power loss, low noise, high output level and extremely outstanding performance/price ratio.
   TON6800W receive optical power range is 1dBm~ -6dBm, the output reaches 108dBm, when the receive optical power is -6dBm, C/N is bigger than 48dB; ~220V or ~60V power supply optional, it turns to +24V、+5V DC to supply the internal components through the high performance switching circuit. Features         ● The structural design, combination is flexible, the application is widespread: independent forward channel, independent optical receiver module, reverse optical transmit module, network management module, power module;
        ● Perfect surge suppression circuit, improved the anti-thunder stroke and surge impact prevention ability;
        ● The input level adopt imported low noise GaAs amplifier, the output level adopt imported CATV high performance, high reliable module, improved C/N and the nonlinear distortion characteristic greatly, simultaneously reduced the complete machine power loss;
        ● Strict reliability test, MTBF is bigger than 100,000 hours;
        ● Forward optical AGC receive power is -6dBm~ +1dBm, the output power change range is ±1dB;
        ● RF output port level adjustable, slope adjustable, output port 1-2;
        ● Reverse channel could adapt TON6800G-B burst reverse transmit module, apply to the high speed data service in the advanced HFC network, it can improve the invasion noise enormously;
        ● Each RF feedback port is equipped with three states reverse noise suppression switch and plug-in attenuator;
        ● RF level monitoring optional, real-time monitor the optical node port’s RF output signal level through the network management system. Open style network management responder optional; satisfies the GB network management standard. Technical Specifications
