MXT-OR-1000NBR-Ⅱ Outdoor 2-output Optical Receiver

MXT-OR-1000NBR-Ⅱ outdoor optical receiver is a kind of new high-quality CATV network product. It adopts GaAs MMIC amplifying component reasonably combined with power doubled amplifying module, AGC/MGC function. When input optical power is in AGC range, 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.

Overview

MXT-OR-1000NBR-Ⅱ outdoor optical receiver is a kind of new high-quality CATV network product. It adopts GaAs MMIC amplifying component reasonably combined with power doubled amplifying module, AGC/MGC function. When input optical power is in AGC range, 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 dual-window receiving;

Single chip can monitor and control output level remotely;

Four-digit high light LED digital tube displays each operation parameters real timely (optical power,

forward path RF output level, forward path RF output attenuation, output voltage);

RF output level, gain and slope can control adjustment (configured network management) or scene

button adjustable remotely.

High reliability switching power supply, small temperature rising, high conversion efficiency, wide

power voltage range;

Optional standard sort II network management responder component, to monitor and control optical

node operation state and performance parameters real timely;

Perfect surge suppression circuit, effective to prevent surge shock and lightning stroke;

Equipped AC60V sole power port, easy to use;

Good quality die-casting aluminum housing, dustproof, waterproof, good shield and heat dissipation,

easy to install.
