Fiber Optic Terminology & Definitions | Fiber Terms Guide
As fiber optic cables pass data, some of this data is naturally lost as it moves across great distances. How much optical power is lost is expressed as attenuation.

Home / How to measure the optical attenuation of multimode fiber
The most accurate way of measuring the fiber attenuation coefficient requires transmitting light of a known wavelength through the fiber and measuring the changes over distance. The core diameter, cladding diameter and concentricity are the most important factors on how well one can connect or splice two fibers. The document gives details on the measurement procedure, which is based on the Electronics Industries Association Recommended Standard as published in RS.
