Product Description
Product Summary
Our company's latest high-end four-output CATV network optical receiver SR814ST, the pre-amplifier uses full GaAs MMIC, and the post-amplifier uses GaAs modules. With optimized circuit design and 10 years of professional design experience, the device has achieved excellent performance indicators. In addition, microprocessor control and digital parameter display make engineering debugging extremely easy. It is the main equipment necessary for building CATV network.
Performance Characteristics
Our advanced CATV network optical receiver SR814ST adopts high-response PIN photoelectric conversion tube, optimizes circuit design and SMT process production, and realizes smooth and efficient transmission of photoelectric signals.
Dedicated RF attenuation chips provide precise linear attenuation, while our GaAs amplifier devices provide high gain and low distortion. The system is controlled by a single-chip microcomputer (SCM), with LCD display parameters, simple and intuitive operation, and stable performance.
The AGC system ensures that the output level remains constant over the optical power range of -9 to +2 dBm with minimal interference from the CTB and CSO. The system also includes a reserved data communication interface, which can be connected to a type II network management responder and connected to the network management system.All technical parameters are measured according to GY/T 194-2003 , under standardized test conditions
