Overview

This type field optical receiver is a kind of latest researched high quality CATV network product. It adopts imported MMIC reasonably combined with GaAs amplification module, optical control AGC function, to make output level keep stable when input optical power in -6~+2dBm, and make this machine have higher performance parameter; Single chip controls LED digital display each operation parameter, to make CATV network project debugging great convenient; meanwhile to transmit digital and analog signal, it is the optimization model for current HFC network system construction.

Features

● 1310nm and 1550nm dual-window receiving;

● Four-digit high bright LED display tube displays machine each operation parameter remotely (optical power, output level, inner temperature, voltage);

● When input optical power in -6~+2dBm, output level keeps constant;

● RF output level, gain and slope are adjustable;

● High reliability switching power, small temperature rising, high conversion efficiency, wide voltage scope;

● Each port equipped AC60V power LED indication light, convenient to operate;

● SNMP component complying with SCTE HMS standard is optional, to monitor optical node operation status, performance real-timely;

● Return path optical transmission unit is hot push-pull type, convenient to upgrade for user;

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

● Equipped AC60V sole power port, convenient to use;

● High quality die-casting aluminum housing, featured with dustproof waterproof, good shield and heat dissipation, convenient to install.
