Product Introduction

SR812S Outdoor Optical Receiver

SR812S-1

Product Overview

SR812S Outdoor Optical Receivers are our universal CATV network optical receiver with network management transponder. The pre-amp adopts all-GaAs MMIC amplify and the post-amp adopts GaAs power double amplify module. Optimized circuit design, coupled with our years professional RF design experience, the equipment achieve high performance index. It is an ideal model for CATV network.

Features

●High response PIN photoelectric conversion tube, 1G bandwidth design.

● Attenuation and equalization can be continuously adjustable knob type or insert type.(Optional)

● Power doubler output, high gain and low distortion.

● Optical AGC control, when the input optical power range is －7～＋2dBm, the output level basically unchanged.

● Optional network transponder, support NMS network management system.
