4 way outdoor hfc optical node
Key Features
High response PIN photoelectric conversion tube.
1G bandwidth design.
Ten bar LED optical power indicators, more accurately display the optical power.
Optimized circuit design, the pre-stage adopts SMT processing, while post-stage adopts module amplify typical circuit that makes the photoelectric signal transmission more smooth.
Power double output, high gain and low distortion.
Optical AGC control, when the input optical power range is - 7~+2dBm, the output level, CTB and CSO basically unchanged.
Can be extended with a remote network management, convenient access to the network management system.
4 Way Outdoor HFc Optical Node can select burst mode to sharply decrease the noise convergence and greatly improve the quality and reliability of the network operation.
