IEC TR 61282-14:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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. Keywords: measurement uncertainty of the attenuation of fibre optic cabling
