Overview

MIC-OR-860NDR-Ⅱseries field optical receiver is a kind of new high-quality CATV network product.It adopts the reasonable combination of GaAs NEC amplifying module,AGC/MGC function.When input optical power is in the range of-6~+2dBm,output level will be stable and it is characterized by high performance index.Single-chip microcomputer controlling LED numeral pipe displays each operating parameter,which makes CATV network project very easy to debug.Digital and analogue signals can be transmitted at the same time.This is the priority choice in HFC network system construction.

Features

●1310nm and 1550nm doul-window receiving;

●Single-chip microcomputer controls AGC/MGC status and output level remotely.

●Four-digit high-bright LED number tube displays the unit’s each operating parameter real-timely(optical power,output level,internal temperature,voltage,current,etc).

●RF output level,gain and slope all can be controlled and modulated remotely(equipped in SNMP)or keys are adjusted.

●High-reliable switching power supply,small temperature rising,high converting efficiency and wide voltage range.

●Each port is equipped AC60V LED indicator light,easy to operate.

●Network manager responder(sort I or II)component complying with SCTE HMS standard can be chosen.Operating status and performance parameter of optical node can be controlled and monitored remotely.

●Perfect surge suppression circuit,it can prevent surge stroke and light stroke efficiently.

●Built-in AC60V sole power port,easy to operate.

●High-quality die-casting aluminum housing,it is characterized by dust-proof,water-proof,good shield and good performance of heat-dissipating,easy to install.
