How to interpret fiber optic loss measurements

This article provides a practical, engineering-oriented explanation of fiber optic loss, focusing on how it affects network performance, how it should be measured and evaluated, and how it can be effectively controlled through better splicing and design practices. There are various causes of fiber optic loss, such as absorption/scattering of light energy by fiber material, bending loss, connector loss, etc. Every fiber link loses some light along the way, and that loss is expressed in dB because the decibel scale makes it easy to add up small losses across long distances. The losses are typically categorized.
