INFORMATION
Overview：
The outdoor optical receiver node caters to standard optical power or ultra-low optical power
receiving, low-noise amplification, high level output technology, good（C/N、CTB、CSO）property, high-quality aluminum tensile alloy shell,
good shielding effect, stable performance, cost-efficiency. It applies to HFC
network and it can realize FTTH, make network easier, lower cost and higher
quality.
The
FTTH catv receiver provide one channel or two channel RF outdoor. The catv
receiver node can be powered by AC220V or AC60V.
Application:
The optical receiver node is an equipment to convert optical signal to RF signal, with amplification
function to achieve transmission of image, sound and data signal.
Technical Feature:
（1）Exclusive use good quality modular PIN tube.
（2）Downlink
signal gallium arsenide dual power output template, high output indicators,
output level can be adjusted.
（3）Protection
circuit is equipped for power supply and control circuit, with low-power consumption design，more stable and reliable for the equipment.
（4）Input
optical power displayed with LED, sensitivity 1dBm, convenient for debugging.
（5）Unique
optical control AGC circuit, making the output optical power unchanged when
input level is between +2 dBm to-8dBm, C \ CTB, C \ CSO is also basically
unchanged.
（6）It
can add network management function, caters to GB/T20030-2005 standard，and
it can monitor the working station, power voltage, output level and receiving
optical power.
Installation Precautions:
（1）Fiber
APC connector has optical output, during repair, avoid eye contact with the
connector.
(2）Optical connector should be clean, clean it by
anhydrous alcohol before connection.
（3）Add AC voltage stabilizer to where voltage fluctuation is large.
（4）Waterproof
measures should be taken outdoors.
（5）Lightning
protection facilities should be equipped in the installation position, the
shell should be well grounded.
