Description
SR812S is our new high-class CATV network optical receiver. The pre-amplifier adopts all-GaAs MMIC, post-amplifier adopts American ACA Company's SMT GaAs device (Or accordance to users' actual needs, using more targeted high quality module combination). Optimized circuit design coordinate with our 10 years design experience, the device achieve high performance index. Microprocessor control, digital display the parameters that make the engineering debug very convenience. It is the main products to build CATV network.
- 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, good RF attenuation and equilibrium linear, high accuracy.
- GaAs amplifier device, power double output, high gain and low distortion.
- Microprocessor control working status, digital display the parameters, convenience and intuitive operation, and stable performance.
- Excellent AGC performance, when the input optical power range is -8~+2dBm, the output level keep unchanged, CTB and CSO basically unchanged.
