Product Description
Product Summary
SR812ST-R is our latest high-grade two-output CATV network optical receiver. The pre-amplifier adopts full-GaAs MMIC, post-amplifier adopts the GaAs module. Optimized circuit design coupled with our 15 years of professional design experience, make the equipment achieve good performance indexes. Microprocessor control, digital display of the parameters, the engineering debugging are especially easy. It is the main equipment to build the CATV network.
Performance Characteristics
- High response PIN photoelectric conversion tube.
- Optimized circuit design, SMT process production, and 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 doubler 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 keeps unchanged, and CTB and CSO basically unchanged.
- Reserved data communication interface, can connect with class Ⅱ network management responder, and access the network management system.
- Return emission can select burst mode to sharply decrease the noise convergence and reduce the forepart receiver number.
