Overview

MIC-OR-200H indoor reverse optical receiver is designed for HFC bi-directional broad-band network.It is mainly used for TV signal picture,telephone voice signal,and data(or packed data)signal to be passed back in the bi-directional metropolitan area network.It adopts low-noise MMIC amplifying circuit and push-pull module amplifying intercombination to ensure the optical receiver has excellent noise index.With rational structure,easily installation and debugging,it is the first choice of constructing HFC bi-directional broad-band network.

Features

●Adopt low-noise optical detector,the distortion is small,and sensitivity is high;

●Built-in high performance low-pass filter.Uplink convergence noise can be effectively suppressed.

●Adopt 19”1U standard all-aluminum frame.Heat radiation performance is good.

●8 independent optical receiving channels.Every receiving channel is independent receiving and amplifying.Output level can be adjusted independently.

●Switching power supply.Small temperature rising,high efficiency,and wide range of voltage adaption.

●SNMP function pre-reservation.
