Rayleigh scattering is caused by non-homogeneities on a small scale that is formed during the fiber construction process. WebThe total fiber loss can be divided into material losses and fiber induced losses. Material losses include Rayleigh scattering, ultraviolet (UV), infrared (IR) absorption, and hydroxyl (OH) absorption losses. Material losses are the limiting losses in fibers. Fiber loss is defined as the ratio of the optical output power Pout from a fiber of ...
