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.
Usually, any bending increases the attenuation of the optical fibers and induces certain losses but micro bending can be more problematic since it cannot be detected by sight A micro bend is a microscopic
