    INFORMATION

    Overview

    The device is a building indoor optical receiver. Optical forward receiver with AGC automatic level control function. When input optical power among -8~0dBm, the constant output level is 78 dbuv.

    The return path of this receiver uses RFOG technology. The reverse laser controls the “burst” mode of the optical node by detecting the input CM signal, thus allowing only one optical node to communicate with the CMTS at any given point in time, thus greatly improving the reverse link noise.

    Schematic Diagram

    Installation, debugging instructions

    1) Install the machine in the shell through the installation holes on both sides of the shell.

    2) Connecting fiber. Be sure to clean the end face of the fiber head before connecting. And be sure to test whether the optical input signal is within the required optical input range. The maximum input light power of this machine must not exceed 3dbm.

    3) Power supply and the indicating light turn on, indicating that the power supply is normal.

    4) Forward optical receiving indicator:Lights up in the AGC range and extinguishes beyond the AGC range.

    5) Return path optical receiving indicator:When there is a return path signal input and reaches the open laser threshold, it turns on. When there is no return path signal input or when the signal is below the laser threshold, it will go out. Since the return path signal is discontinuous, the return path optical indicator will flash.

    Note:The light signal is invisible laser beam, exposure to the eye directly may cause permanent injury.
