Optical fibres - Part 1-22: Measurement methods and test procedures - Length measurement (IEC 60793-1-22:2024)
IEC 60793-1-22:2024 establishes uniform requirements for measuring the length and elongation of optical fibre (typically within cable). The length of an optical fibre is a fundamental value for the evaluation of transmission characteristics such as losses and bandwidths.

Fibres optiques - Partie 1-22: Méthodes de mesure et procédures d'essai - Mesure de la longueur (IEC 60793-1-22:2024)
L’IEC 60793-1-22:2024 établit des exigences uniformes pour mesurer la longueur et l’allongement de la fibre optique (typiquement dans le câble). La longueur d’une fibre optique est une valeur fondamentale pour l’évaluation des caractéristiques de transmission, telles que les pertes et la bande passante.
Optična vlakna - 1-22. del: Merilne metode in postopki preskušanja - Merjenje dolžine (IEC 60793-1-22:2024)
Standard IEC 60793-1-22:2024 določa enotne zahteve za merjenje dolžine in raztezanja optičnih vlaken (običajno znotraj kabla). Dolžina optičnega vlakna je temeljna vrednost za ocenjevanje prenosnih lastnosti, kot so izgube in pasovne širine.
