Fibre optic communication subsystem test procedures - Part 4-3: Installed passive optical networks - Attenuation and optical return loss measurements
IEC 61280-4-3: 2022 describes the measurement of attenuation, optical return loss and optical power in installed passive optical networks (PONs) using single-mode fibre. This document specifies two methods for measuring the attenuation before activation of the PON:
method A: one-cord method using a light source and a power meter (LSPM);
method B: optical time-domain reflectometer (OTDR) method in upstream direction only, with reduction of uncertainties due to the variation of backscatter coefficient. In addition, method C, which is described in informative Annex C, provides an estimate of the attenuation after partial activation of the PON by using a U band filtered optical time-domain reflectometer (FOTDR) in an upstream direction. This publication contains an attached file titled "Supplemental Data" in the form of an Excel spread sheet. This file is intended to be used as a complement and does not form an integral part of the standard.

Procédures d’essai des sous-systèmes de télécommunications fibroniques - Partie 4-3: Installations de réseau optique passif - Mesures de l’affaiblissement et de l’affaiblissement de réflexion optique
IEC 61280-4-3: 2022 décrit la mesure de l’affaiblissement, de l’affaiblissement de réflexion optique et de la puissance optique dans des installations de réseau optique passif (PON) utilisant de la fibre unimodale. Le présent document spécifie deux méthodes pour mesurer l’affaiblissement avant l’activation du PON:
méthode A: méthode à cordon unique utilisant une source optique et un mesureur de puissance (LSPM);
méthode B: méthode au réflectomètre optique dans le domaine temporel (OTDR), uniquement dans le sens ascendant, offrant une réduction des incertitudes associées à la variation du coefficient de rétrodiffusion. En outre, une méthode C, décrite à l’Annexe C informative, donne une estimation de l’affaiblissement après activation partielle du PON, en utilisant un réflectomètre optique dans le domaine temporel à port filtré (FOTDR, Filtered Optical Time-Domain Reflectometer), fonctionnant sur la bande U dans le sens ascendant. Cette publication contient un fichier joint intitulé "Données complémentaires", sous forme de feuille de calcul Excel. Ce fichier est destiné à être utilisé comme complément, et ne fait pas partie intégrante de la norme.
Postopki preskušanja optičnega komunikacijskega podsistema - 4-3. del: Vgrajena pasivna optična omrežja - Meritve slabljenja in optičnih povratnih izgub (IEC 61280-4-3:2022)
Ta del standarda IEC 61280 opisuje meritve slabljenja, optične povratne izgube in optične moči v nameščenih pasivnih optičnih omrežjih (PON) z enorodnimi vlakni. Ta dokument določa dve metodi merjenja slabljenja pred aktiviranjem PON: • metoda A: enorodna metoda z uporabo vira svetlobe in merilnika moči (LSPM); • metoda B: metoda optičnega reflektometra v časovni domeni (OTDR) samo v smeri proti toku, z zmanjšanjem negotovosti zaradi variacije koeficienta povratnega razprševanja. Poleg tega metoda C, ki je opisana v informativnem dodatku C, zagotavlja oceno slabljenja po delni aktivaciji PON z uporabo optičnega reflektometra v časovni domeni (FOTDR) s filtriranim pasom U v smeri proti toku.
