TON6800HⅡ Optical Node

Overview        TON6800HII optical node can be used for CATV network, digital network and telecom network. It is especially suitable for the FTTx network where the fiber is extended to the building, and output directly cover subscribers.
       TON6800HII input optical power range is ＋2dBm～－8dBm, output is above 108dBuV. When the receiving optical power is －6dBm, C/N＞47dB.
       220V or 60V power supply optional, the high-performance conversion circuit enable it turn into +24V, +5V DC power to supply the optical receiver internal device. Features         ● Flexible Structural design, wide application: forward optical receiver, reverse optical transmitter or reverse RFoG;
        ● Perfect surge suppression circuitry, improved the anti-lightning strike and the prevention of lightning surge shocks;
        ● Input stage adopt imported low-noise GaAs amplifier, output stage adopt imported CATV high-performance, high reliability amplify module, greatly improved the C/N and non-linear distortion characteristics while significantly reducing the power consumption;
        ● Rigorous reliability test, MTBF ＞100,000 hours;
        ● Forward AGC function, optical power at the range -6dBm～+2dBm, the output level change within ±1dB;
        ● RF output level fixed-adjustable, slope adjustable; 1～2 output ports optional, split/tap optional for 2 output ports;
        ● Network management interface transponder can be reversed, good for remote monitoring. Technical Specifications
