Optical fibres - Part 1-41: Measurement methods and test procedures - Bandwidth
IEC 60793-1-41:2024 is available as IEC 60793-1-41:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60793-1-41:2024 describes three methods for determining and measuring the modal bandwidth of multimode optical fibres (see IEC 60793-2-10, IEC 60793-2-30, and the IEC 60793‑2‑40 series). The baseband frequency response is directly measured in the frequency domain by determining the fibre response to a sinusoidaly modulated light source. The baseband response can also be measured by observing the broadening of a narrow pulse of light. The calculated response is determined using differential mode delay (DMD) data. The three methods are: Method A – Time domain (pulse distortion) measurement Method B – Frequency-domain measurement Method C – Overfilled launch modal bandwidth calculated from differential mode delay (OMBc) Method A and method B can be performed using one of two launches: an overfilled launch (OFL) condition or a restricted mode launch (RML) condition. Method C is only defined for A1-OM3 to A1-OM5 multimode fibres and uses a weighted summation of DMD launch responses with the weights corresponding to an overfilled launch condition. The relevant test method and launch condition is chosen according to the type of fibre. NOTE 1 These test methods are commonly used in production and research facilities and are not easily accomplished in the field. NOTE 2 OFL has been used for the modal bandwidth value for LED-based applications for many years. However, no single launch condition is representative of the laser (e.g. VCSEL) sources that are used for gigabit and higher rate transmission. This fact drove the development of IEC 60793-1-49 for determining the effective modal bandwidth of laser optimized 50 µm fibres. See IEC 60793-2-10 and IEC 61280-4-1 for more information. This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the addition of a direct reference for method A and method B.

Fibres optiques - Partie 1-41: Méthodes de mesure et procédures d'essai - Largeur de bande
IEC 60793-1-41:2024 est disponible sous forme de IEC 60793-1-41:2024 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60793-1-31:2024 décrit trois méthodes pour déterminer et mesurer la largeur de bande modale des fibres optiques multimodales (voir l’IEC 60793-2-10, l’IEC 60793-2-30 et l’IEC 60793‑2‑40). La réponse en fréquence de bande de base est directement mesurée dans le domaine fréquentiel en déterminant la réponse de la fibre à une source de lumière modulée de manière sinusoïdale. La réponse en bande de base peut aussi être mesurée en observant l’élargissement d’une impulsion étroite de lumière. La réponse calculée est déterminée en utilisant les données de retard différentiel de mode (DMD, Differential Mode Delay). Les trois méthodes sont les suivantes: Méthode A – Mesure dans le domaine temporel (distorsion d’impulsion) Méthode B – Mesure dans le domaine fréquentiel Méthode C – Largeur de bande modale avec injection saturée calculée à partir du retard différentiel de mode (OMBc, Overfilled launch Modal Bandwidth calculated) Les méthodes A et B peuvent être réalisées en utilisant une méthode d’injection au choix entre: une condition d’injection saturée (OFL, OverFilled Launch) ou une condition d’injection en mode partiel (RML, Restricted Mode Launch). La méthode C est seulement définie pour les fibres multimodales A1-OM3 à A1-OM5 et utilise une sommation pondérée des réponses d’injection de DMD avec les pondérations correspondant à une condition d’injection saturée. La méthode d’essai et la condition d’injection appropriées sont choisies en fonction du type de fibre. NOTE 1 Ces méthodes d’essai sont fréquemment utilisées dans les installations de production et de recherche et ne sont pas facilement réalisées sur site. NOTE 2 La méthode OFL est utilisée depuis de nombreuses années pour la valeur de largeur de bande modale des applications à base de LED. Toutefois, aucune condition d’injection unique n’est représentative des sources laser (par exemple, les diodes laser à cavité verticale émettant par la surface [VCSEL, Vertical-Cavity Surface-Emitting Laser]) qui sont utilisées pour la transmission en gigabits et à des débits supérieurs. Ceci a conduit à l’élaboration de l’IEC 60793-1-49 pour la détermination de la largeur de bande modale effective des fibres à 50 µm optimisées pour les sources laser. Voir l’IEC 60793-2-10:2019 ou plus récente et l’IEC 61280-4-1:2019 ou plus récente pour plus d’informations. Cette quatrième édition annule et remplace la troisième édition parue en 2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) l’ajout d’une "référence directe" pour la méthode A et la méthode B.
