Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-35: Examinations and measurements - Visual inspection of fibre optic connectors and fibre-stub transceivers
IEC 61300-3-35:2022 is concerned with the observation and classification of debris, scratches and defects. The inspection requirements are based on IEC TR 62627-05. Advice for cleaning of contamination from fibres/ferrule is found in IEC TR 62627-01 and a recommendation is given in Annex D. IEC TR 62572-4 provides the cleaning method for a stub for optical transceivers. Visual inspection is in addition to, and does not replace measurement of performance parameters such as attenuation and return loss, or end face parameters. The dimensions specified are chosen such that they can be easily estimated. Not only the zones A and B on the fibre are inspected for defects and scratches but the whole contact area (where the two fibres/ferrules meet when mated) needs to be inspected for contamination (this is up to 250 µm diameter for cylindrical ferrules and the whole ferrule surface for rectangular ferrules).The objectives of this document are the following: - specify the minimum criteria for a microscope to be compliant to this document; - specify the procedure and criteria for inspecting fibre-optic end faces for cleanliness to determine if the end faces are fit for use. All connector optical interfaces (IEC 61755 series and IEC 63267 series) are based on physical contact between fibre cores; - provide quantitative criteria for the analysis of end face images. This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - adding of a statement that visual inspection is not a substitute for optical qualification such as attenuation and return loss measurement; - adding of some terms and definitions; - adding requirements for SM 35 dB connectors; - adding of a sentence in Clause 5 concerning the susceptibility of the methods to system variability and variability within systems from same supplier; - removal of inspection requirements for zones C and D; - insertion of a generic cleanliness specification for whole rectangular ferrule and 250 µm area around every fibre; - adding a cleaning recommendation for rectangular and cylindrical ferrules; - outer edge of inspection zone B has changed from 115 µm to 110 µm to meet manufacturing tolerances of fixture for microscopes; - change that defects that are partly in core are only to be judged for the part they are in the core. The remainder of the defect is considered to be located in the cladding. - adding a statement that a connector cannot be rejected by just failing visual inspection. Meeting the specified optical performance determines the use of this connector.

L'IEC 61300-3-35:2022 porte sur l’observation et la classification des débris, des éraflures et des défauts. Les exigences d’examen sont fondées sur l’IEC/TR 62627-05. L’IEC/TR 62627-01 fournit des conseils pour le nettoyage de la contamination des fibres/férules et l’Annexe D donne une recommandation. L’IEC/TR 62572-4 fournit la méthode de nettoyage d’une embase pour émetteurs-récepteurs optiques. L’examen visuel s’ajoute à la mesure des paramètres de performance tels que l’affaiblissement et d’affaiblissement de réflexion, ou les paramètres aux extrémités, et ne les remplace pas. Les dimensions spécifiées ont été choisies de manière à faciliter leur estimation. Non seulement les zones A et B de la fibre sont examinées afin de déterminer l’éventuelle présence de défauts et d’éraflures, mais il est également nécessaire d’examiner la totalité de la surface de contact (l’endroit où les deux fibres/férules se rencontrent une fois accouplées) afin de détecter une éventuelle contamination (c’est-à-dire jusqu’à un diamètre de 250 µm pour les férules cylindriques et la totalité de la surface des férules rectangulaires). Le présent document a pour objectifs de: - spécifier les critères minimaux pour qu’un microscope soit conforme au présent document; - spécifier la procédure et les critères d’examen de la propreté des extrémités des fibres optiques afin de déterminer si ces extrémités sont aptes à l’emploi. Toutes les interfaces optiques des connecteurs (séries IEC 61755 et IEC 63267) reposent sur un contact physique entre les cœurs des fibres; - fournir des critères quantitatifs pour l’analyse des images des extrémités. Cette troisième édition annule et remplace la deuxième édition parue en 2015. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: - ajout d’une mention stipulant qu’un examen visuel ne remplace pas une qualification optique telle qu’une mesure d’affaiblissement et d’affaiblissement de réflexion; - ajout de plusieurs termes et définitions; - ajout d’exigences concernant les connecteurs SM 35 dB; - ajout d’une phrase à l’Article 5 concernant la susceptibilité des méthodes à la variabilité du système et à la variabilité au sein des systèmes provenant d’un même fournisseur; - suppression des exigences d’examen pour les zones C et D; - insertion d’une spécification générique concernant la propreté de la totalité d’une férule rectangulaire et d’une zone de 250 µm autour de chaque fibre; - ajout d’une recommandation de nettoyage des férules rectangulaires et cylindriques; - changement du bord extérieur de la zone d’examen B de 115 µm à 110 µm pour satisfaire aux tolérances de fabrication des microscopes; - modification concernant les défauts en partie situés dans le cœur à considérer uniquement comme étant dans cette partie. Le reste du défaut est considéré comme étant situé dans la gaine; - ajout d’une mention stipulant qu’un connecteur ne peut pas être rejeté après un simple examen visuel. Si la performance optique spécifiée de ce connecteur est satisfaite, il convient d’utiliser ce dernier.
Optični spojni elementi in pasivne komponente - Osnovni preskusni in merilni postopki - 3-35. del: Preiskave in meritve - Vizualno pregledovanje optičnih konektorjev in sprejemnikov-oddajnikov z vlakenskimi tulkami (IEC 61300-3-35:2022)
Ta del standarda IEC 61300 obravnava opazovanje in razvrščanje umazanije, prask in napak. Zahteve glede pregledov temeljijo na standardu IEC TR 62627-05. V standardu IEC TR 62627-01 je podan nasvet za čiščenje onesnaženih vlaken/tulk, v dodatku D pa je podano priporočilo. Standard IEC TR 62572-4 podaja metodo čiščenja tulk za optične sprejemnike-oddajnike. Vizualni pregled je dodatek in ne nadomešča merjenja parametrov zmogljivosti, kot sta slabljenje in povratna izguba, ali parametrov končne površine. Navedene mere so izbrane tako, da jih je mogoče enostavno oceniti. Poleg pregledovanja morebitnih napak in prask v območjih A in B na vlaknu je treba pregledati tudi celotno kontaktno območje (kjer se dve vlakni/tulki pri spajanju stikata) ter se tako prepričati, da ni onesnaženo (tj. do premera 250 µm pri cilindričnih tulkah in celotno površino tulke pri pravokotnih tulkah).
Cilji tega dokumenta so:
• določitev minimalnih meril za skladnost mikroskopa s tem dokumentom;
• določitev postopka in meril za pregledovanje čistosti končnih površin optičnih vlaken, da se ugotovi njihova primernost za uporabo. Vsi vmesniki optičnih konektorjev (skupini standardov IEC 61755 in IEC 63267) temeljijo na fizičnem stiku med vlakenskimi jedri;
• zagotovitev kvantitativnih meril za analizo slik končnih površin.
