Overview
MXT-OR-860JBN series outdoor optical receiver is a kind of new CATV network product. It adopts GaAs MMIC amplifying component reasonably combined with GaAs amplifying module. AGC/MGC function is optional, which makes output level keep stable when input optical power is -6~+1dBm, and also makes the machine has higher performance index. It is also possible to realize output level and slope's control through network management system to machine, and makes it has higher performance index, as well as making CATV network project very convenient to debug. Meanwhile can transmit digital and analogue signal. This is FTTH main-stream machine type in current HFC network system construction.
Features
● 1310nm and1550nm dual-window receiving.
● LED numeral pipe displays each operation parameter real-timely ( optical power, attenuation,
equalization, output level, voltage, current).
● Key to select, adjust RF output level and slope.
● Output is plug-in 1-way tap or 2-way splitter, easy to replace and use.
● AGC/MGC function, it makes output level stable when input optical power is -6~+1dBm.
● High-reliability switch power supply, small temperature rising, high conversion efficiency and wide
adaptable voltage range.
● Each port is equipped AC60V supply power LED indicator light, easy to use.
● Perfect surge suppression circuitry, which is efficient to prevent surge stroke and lightning.
● Equipped AC60V sole power port, easy to use.
● High-quality small die-casting aluminum shell, it is characterized by dust-proof, water-proof, good
shield and heat-dissipating, easy to install.
