Optical fibres - Part 1-44: Measurement methods and test procedures - Cut-off wavelength
IEC 60793-1-44:2011 establishes uniform requirements for measuring the cut-off wavelength of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. This standard gives the methods for measuring the cut-off wavelength of fibre and cable. This edition constitutes a technical revision. The main change with respect to the previous edition is the withdrawal of Annex D. This publication is to be read in conjunction with IEC 60793-1-1:2008.

Fibres optiques - Partie 1-44: Méthodes de mesure et procédures d'essai - Longueur d'onde de coupure
La CEI 60793-1-44:2011 établit des exigences uniformes pour mesurer la longueur d'onde de coupure des fibres optiques unimodales, contribuant ainsi au contrôle des fibres et câbles dans des relations commerciales. La présente norme donne les méthodes de mesure de la longueur d'onde de coupure de fibre et de câble. Cette deuxième édition annule et remplace la première édition parue en 2001. Elle constitue une révision technique. La principale modification par rapport à l'édition précédente consiste en la suppression de l'Annexe D. Cette publication doit être lue conjointement avec la CEI 60793-1-1:2008.
Optična vlakna - 1-44. del: Metode merjenja in preskusni postopki - Mejna valovna dolžina (IEC 60793-1-44:2011)
Ta del IEC 60793 vzpostavlja enotne zahteve za merjenje mejne valovne dolžine enorodnih optičnih vlaken in je z njimi opora pri pregledovanju vlaken in kablov v komercialne namene. Ta standard navaja metode za merjenje mejne optične dolžine vlaken in kablov. Za merjenje mejne valovne dolžine kablov obstajata dve metodi, l cc:? Metoda A: z uporabo vlaken zunaj kabla; ? Metoda B: z uporabo vlaken v kablu. Za merjenje mejne valovne dolžine vlaken, 1 c, obstaja samo ena metoda (metoda C). Preskusna metoda v tem standardu opisuje postopke za določanje mejne valovne dolžine vzorčnega vlakna v stanju zunaj kabla (l c) ali v kablu (l cc). Podane so tri privzete konfiguracije: vsaka drugačna konfiguracija je navedena v podrobni specifikaciji. Ti postopki veljajo za vse vrste vlaken kategorij B in C (glej Normativne reference). Vse metode zahtevajo referenčno meritev. Obstajate dve tehniki z referenčnim odčitavanjem in obe se lahko uporabljata z vsemi metodami: ? tehnika z referenčnim upogibanjem; tehnika z večrodno referenco z uporabo večrodnega vlakna kategorije A1.
