Backbone The cabling used to connect entrance facilities, crossconnects, telecommunications closets, and equipment rooms. The backbone may consist of either interbuilding and/or intrabuilding cabling. Backreflection The loosely-used term covers optical return loss (ORL) for spans, reflectance for components, and Fresnel reflectance. Backscatter coefficient The ratio of the optical pulse power (not energy) at the OTDR […]

Glossary start with Letter A: Abrasion resistance The surface ware resistance of the fiber optic cable. Absorption Caused by impurities introduced during the manufacturing process, absorption creates loss in a fiber by turning light energy into heat. The amount of absorption is determined by the wavelength and depends upon the composition of the glass or plastic. […]
