Product Discription:
SR812B series are our universal CATV network optical receiver with network management responder. The pre-amp adopts all-GaAs MMIC amplify and the post-amp adopts GaAs power double amplify module (This series has two models, M model RF attenuation and equilibrium adopt the continuously adjustable design, MF model with different fixed attenuation and equilibrium inserters for user option. Users can also choose more targeted high quality modules according to actual requirements). Optimized circuit design, coupled with over years professional RF design experience, the equipment achieve high performance index. It is an ideal model for CATV network
| Features: |
1. High response PIN photoelectric conversion tube. 2. 1G bandwidth design. 3. Ten bar LED optical power indicators, more accurately display the optical power. 4. Optimized circuit design, the pre-stage adopts SMT processing, while post-stage adopts module amplify typical circuit that makes the photoelectric signal transmission more smooth. 5. Power double output, high gain and low distortion. 6. Optical AGC control, when the input optical power range is -7~+2dBm, the output level, CTB and CSO basically unchanged. 7. Can be extended with a remote network management, convenient access to the network management system. |
