HFC Optical Node
SR814/SR814R is a high-grade four-way outdoor HFC Optical Node. It is the main equipment to build the CATV network.
Performance Characteristics
High response PIN photoelectric conversion tube.
Optimized circuit design, SMT process production, optimized signal path, make the
photoelectric signal transmission more smooth.
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.
Single Chip Microcomputer (SCM) control equipment working, LCD display the parameters,
convenience and intuitive operation, and stable performance.
Excellent AGC performance, when the input optical power range is －9～＋2dBm, the output
level keep unchanged, CTB and CSO basically unchanged.
Reserved data communication interface, can connect with class Ⅱ network management
responder, access to network management system.
Return path can select burst mode to sharply decrease the noise convergence and greatly
increase thequality and reliability of network operation.
