Overview
MXT-OR-860JBNS indoor optical receiver is a kind of latest promoted CATV network products. This machine adopts GaAs MMIC amplifier component reasonably combined with NEC GaAs amplifier module. AGC/MGC function key can be optional, which makes output level keep stable when input optical power is -6~+1dBm to make his equipment have higher performance index; It can realize output level and slope control of the machine completely through network management system to make the machine have higher performance index, as well as make CATV network project very easy to debug. Meanwhile can transmit digital and analogue signals. It is the best option in HFC network system construction currently.
Features
● 1310nm and 1550nm dual-window receiving;
● LED digital tube can display each operation parameter of the equipment real-timely (optical power,
attenuation, equalization, output level, voltage, current, etc).
● Key is optional to adjust RF output level and slope.
● Output is plug-in one-way tap or two-way splitter, easy to replace and use.
● AGC/MGC function, it makes output level keep stable when input optical power is -6~+1dBm.
● High reliability switch power supply, small temperature rising, high conversion efficiency, wide voltage
range.
● High quality small-type aluminium housing, it's characterized by good shield and heat-dissipating,
easy to install.
