EN 60793-1-48:2007

Optical fibres - Part 1-48: Measurement methods and test procedures - Polarization mode dispersion

Applies to three methods of measuring polarization mode dispersion (PMD). Establishes uniform requirements for measuring the PMD of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. In this edition, reference to IEC 61282-9 has resulted in the removal of Annexes E, F, G and H as well as the creation of a new Annex E.

Lichtwellenleiter - Teil 1-48: Messmethoden und Prüfverfahren - Polarisationsmodendispersion

Fibres optiques - Partie 1-48: Méthodes de mesure et procédures d'essai - Dispersion du mode de polarisation

S'appliques aux trois méthodes de mesure de la dispersion de mode de polarisation (Polarization Mode Dispersion, PMD). Elle établit des exigences uniformes pour mesurer la PMD d'une fibre optique unimodale, de façon à aider dans l'examen des fibres et des câbles à des fins commerciales. Dans cette édition, la référence à la CEI 61289-2 a entraîné le retrait des Annexes E, F, G et H ainsi que la création d'une nouvelle Annexe E.
