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

Applies to three methods of measuring PMD. Uniform requirements for measuring the PMD of optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes are established.

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

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

S'applique à trois méthodes de mesure de la dispersion de mode de polarisation (PMD). Elle établit les prescriptions uniformes pour mesurer la PMD de la fibre optique contribuant ainsi au contrôle des fibres et des câbles dans les relations commerciales.
