| description | The utility model provides a poor raman optical fiber amplifier who surveys that decreases in area, its structure includes: a WDM, first coupler, first detector, second detector, isolator, pumping and CPU, wherein, CPU sends electric pulse to pumping, and the pumping is exported after converting the electric pulse into light pulse, and the light pulse exports the key light way to behind isolator, first coupler, a WDM, reverse ruili scattered light is received by CPU behind a WDM, first coupler, second detector, whether with reflection normal, whether the circuit has the fracture if can survey the poor damage of transmission fiber before raman optical fiber amplifier opens, whether the connector terminal surface is connected well, fiber connector terminal surface and protection engineering personnel prevent to burn out. |
