EN IEC 61300-3-4:2023

Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-4: Examinations and measurements - Attenuation

IEC 61300-3-4:2023 is available as IEC 61300-3-4:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61300-3-4: 2022 describes the various methods available to measure the attenuation of optical components. It is not, however, applicable to random mate attenuation measurements as described in IEC 61300-3-34 and IEC 61300-3-45 nor for attenuation measurements of dense wavelength division multiplexing (DWDM) devices as described in IEC 61300-3-29. This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of Clause 3 containing terms, definitions and abbreviated terms; b) addition of a new LSPM measurement method, insertion method (D); c) addition of Annex A describing attenuation measurement of multicore fibre; d) changed reference test method to insertion C and alternative test method to substitution or insertion D for power meter and type 4 DUT.

IEC 61300-3-4:2023 est disponible sous forme de IEC 61300-3-4:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 61300-3-4:2023 décrit les différentes méthodes disponibles qui permettent de mesurer l’affaiblissement des composants optiques. Toutefois, elle n’est applicable ni aux mesurages de l’affaiblissement dû à l’accouplement aléatoire décrits dans l’IEC 61300-3-34 et l’IEC 61300-3-45 ni aux mesurages de l’affaiblissement des dispositifs de multiplexage par répartition en longueur d’onde à forte densité (DWDM - dense wavelengths division multiplexer) décrits dans l’IEC 61300-3-29. Cette quatrième édition annule et remplace la troisième édition parue en 2012. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) ajout de l’Article 3 relatif aux termes, définitions et abréviations; b) ajout d'une nouvelle méthode de mesure LSPM, la méthode par insertion (D); c) ajout de l’Annexe A qui décrit le mesurage de l'affaiblissement de la fibre multicœur; d) modification de la méthode d'essai de référence par insertion C et de la méthode d'essai alternative par substitution ou par insertion D pour l’appareil de mesure de la puissance et le DUT de type 4.

Optični spojni elementi in pasivne komponente - Osnovni preskusni in merilni postopki - 3-4. del: Preiskave in meritve - Slabljenje (IEC 61300-3-4:2023)

Standard IEC 61300-3-4:2023 je na voljo kot SIST IEC 61300-3-4:2023, ki vsebuje mednarodni standard in njegovo različico z revizijami, ki prikazujejo vse spremembe tehnične vsebine v primerjavi s prejšnjo izdajo. Standard IEC 61300-3-4: 2022 opisuje različne metode, ki so na voljo za merjenje slabljenja optičnih komponent. Vendar se ne uporablja niti za meritve slabljenja naključnih spojitev, kot je opisano v standardih IEC 61300-3-34 in IEC 61300-3-45, niti za meritve slabljenja naprav za zgoščeno valovnodolžinsko multipleksiranje (DWDM), kot je opisano v standardu IEC 61300-3-29. Četrta izdaja razveljavlja in nadomešča tretjo izdajo, objavljeno leta 2012. Ta izdaja je tehnično popravljena izdaja. Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
a) dodana točka 3, ki vsebuje izraze, definicije, simbole in okrajšave izrazov;
b) dodana nova merilna metoda z virom svetlobe in merilnikom moči (LSPM), metoda vstavljanja (D);
c) dodan dodatek A, ki opisuje merjenje slabljenja večžilnega vlakna;
d) spremenjena referenčna preskusna metoda za vstavljanje C in alternativna preskusna metoda za zamenjavo ali vstavljanje D za merilnik moči in tip 4 DUT.
