Description
The outdoor optical receiver input normal optical power or ultra-low optical power and convert the optical to electrical signal, then low-noise amplify the CATV electrical signal and output high level RF signal. The optical receiver node has stable performance because of its high-quality aluminum tensile alloy shell which has good shielding effect. The FTTH catv optical receiver provide two way RF output. The catv receiver node can be powered by AC220V or AC60V. It is suitable for areas where power is not convenient, single unit with multiple users.
Technical Feature:
- Exclusive use good quality modular PIN tube.
- Downlink signal gallium arsenide dual power output template, high output indicators, output level can be adjusted.
- Protection circuit is equipped for power supply and control circuit, with low-power consumption design，more stable and reliable for the equipment.
- Input optical power displayed with LED, sensitivity 1dBm, convenient for debugging.
- Unique optical control AGC circuit, making the output optical power unchanged when input level is between +2 dBm to-8dBm.
- The outdoor optical receicer can add network management function, it can monitor the working station, power voltage, output level and receiving optical power.

Application
The optical receiver node is suitable for HFC network application, which achieves transmission of image, sound and data signal. The optical node makes FTTH network easier, lower cost and higher quality.
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.
