Overview

SK-OR-860JC optical receiver is a kind of latest CATV network product. It adopts the reasonable combination of GaAs MMIC circuit and GaAs power amplification module, with AGC/MGC function, which makes output level stable and has good performance as input optical power is in the range of -8~0dBm. Single-chip microcomputer controlling high-bright LED digital tube displays its each item of operation parameters to make CATV network project very convenient to debug. Digital signal and analogue signal can be transmitted at the same time. It is the priority in the present HFC network system construction.

Features

● 1310nm and 1550nm dual-window receiving;

● LED digital tube displays each item of operation parameters real-timely(optical power, attenuation, equalization, etc.);

● Key can be optional and adjusts RF output level and slope;

● AGC/MGC function, it can make output level stable when input optical power is in the range of -8~0dBm;

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

● Perfect surge suppression circuitry, which can prevent surge stroke and light stroke efficiently;

● With network management transponder which meet SNMP, the user can make management for the device through network management system or web;

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