1,Overview: (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.
2,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)Lightning protection facilities should be equipped in the installation position, the shell should be well grounded.
3,Diagrammatic Layout:YTMINI-2N 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.
4,Application:YTMINI-2-N Optical Receiver is an equipment to convert optical signal to RF signal, with amplification function to achieve transmission of image, sound and data signal.
