A Quantitative Determination of Different Optical Loss Mechanisms in Long Haul Telecommunications

Abstract

For long distance fiber optic communication, there is always a chance for the optical fiber to bend with very small radius especially at the joints which results in the attenuation of optical power as bending loss. This paper throws light in to the various loss mechanisms of loss in fiber optic communication.  Numerous mechanisms are responsible for attenuation of signals in fiber optics. In this study, a method of detecting bending loss is dealt. This study reflects the propagation loss in the fiber and also tries to feel the coupling losses so that it helps the fiber industry players to determine the exact location where the loss happened and rectification can be done to solve the bend loss. As the optical signal traverses long stretch distance of fiber, it suffers attenuation due to scattering, absorption, bending of optical fiber, impurities present in the material and due to other effects. The advancements in the attenuation properties are discussed in this paper.
