Fiber Optic Microbending Sensing Experiment
This paper highlights the results of a series of tests conducted, to determine the power loss of matched clad step index Single Mode Optical Fiber (SMF). The effect of MFD, Cut-off wavelength and MAC value have been studied with various macro and micro bend testing techniques. Another useful dimension of fiber optics is that it has also provided a revolutionary technology base for configuring a variety of optical sensors, which offer several advantages their small size and mechanical flexibility. The loss of optical power in a single mode due to bending has been investigated at. Intensity modulation induced by microbending in multimode fibers is considered as a transduction mechanism for detecting environmental changes such as pressure, temperature, acceleration, and magnetic and electric fields.
