Outdoor Optical Node
Brief introduction of outdoor optical node
Outdoor optical node is our latest high-grade two-output CATV network optical receiver. The pre-amplifier adopts full-GaAs MMIC, post-amplifier adopts GaAs module. Optimized circuit design coupled with our 10 years professional design experience, make the equipment achieve good performance indexes. Microprocessor control, digital display the parameters, the engineering debug is especially easy. It is the main equipment to build the CATV network.
Performance Characteristics of outdoor optical node
1, High response PIN photoelectric conversion tube.
2, Specialized RF attenuation chip, with good RF attenuation and equilibrium linear, high accuracy.
GaAs amplifier device, power doubly output, with high gain and low distortion.
3, Excellent AGC performance, when the input optical power range is －9～＋2dBm, the output level keep unchanged, CTB and CSO basically unchanged.
4, Reserved data communication interface, can connect with class Ⅱ network management responder, access to network management system.
