Vibration Optical Fiber Alarm System, Climb and Damage Trigger Alarm

Product Description

Vibration Optical Fiber alarm system
The working principle of the vibrating fiber is that the launching laser emits a DC monochromatic light wave, which is coupled into the two-core sensing fiber in the forward and reverse directions through the fiber coupler, forming a forward and reverse loop Mach-Zehnder interference optical signal; After the optical fiber is disturbed by external vibration along the line, it will cause the phase change of the light wave in the optical fiber transmission, forming an optical signal phase modulation sensing signal based on double-loop Mach-Zehnder interference, which is transmitted to the photodetector through the optical fiber coupler and optical circulator , Detect the light intensity change of the interference light signal, and realize the fiber vibration alarm.
