Factors Affecting Multimode Fiber Attenuation
Attenuation is caused by passive media components such as cables, cable splices, and connectors. Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber). Two different methods exist for splicing fibers: Typical splice loss values (the measure of loss in optical power across the splice point) are usually lower for fusion splices (typically less than 0. This signal loss is inevitable and affects the quality and distance over which data can be transmitted.
