Fibre optic communication system design guidelines - Part 14: Determination of the uncertainties of attenuation measurements in fibre plants

Апстракт

IEC TR 61282-14:2019 which is a Technical Report, establishes the detailed analysis and calculation of the uncertainties related to the measurement of the attenuation of both multimode and single mode optical fibre cabling using optical light sources and power meters. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- in the title: replacement of "guide" by "guidelines";
- text adaptation to allow both standard grade B and reference grade connectors for termination of test cords;
- addition of values needed for calculation of uncertainties, when standard grade connectors are used, to Annex D;
- correction of minor inconsistencies in Equation (18) and after.
