Connector sets and interconnect components to be used in optical fibre communication systems - Product specifications Part 14-1: Simplex and duplex cords made from simplex plugs with cylindrical ferrules, using EN 60793-2-50 single-mode B-652 or B-657 fibre for Category C according to EN 61753-1

1.1 Product definition This document contains the initial, start of life, dimensional, optical, mechanical and environmental performance requirements that an assembled single mode cord with cylindrical ferruled connectors will meet in order for it to be categorized as an EN standard product. Since different variants and grades of performance are permitted, product marking details are given in 4.5 and Clause 5. 1.2 Intermateability of the plugs Where the products conforming to the requirements of this document are intermateable, the resulting level of random attenuation performance will be in accordance with Table 1. The intention is that this will be true irrespective of the manufacturing source(s) of the product. When intermating plug variants having different attenuation grades (as specified in EN 61755 1) the resulting level of attenuation cannot be any better than the worst attenuation grade of the individual plugs. Intermating a grade C plug with a grade B plug will result in a grade C level of random attenuation performance.

This is predicted using a recognized reliability assessment program. 1.5 Quality assurance Compliance with this standard does not guarantee the manufacturing consistency of the product. This is expected to be maintained using a recognized quality assurance program.

1.1 Définition du produit Le présent document contient les exigences de performances initiales, dimensionnelles en début de vie, optiques, mécaniques et environnementales auxquelles un cordon unimodal assemblé avec un connecteur à férule cylindrique satisfait afin d’être classé comme produit entrant dans une norme européenne de produit. Dans la mesure où différentes variantes et différentes classes de performances sont autorisées, les détails de marquage des produits sont donnés en 4.5 et à l’Article 5. 1.2 Compatibilité d’accouplement des fiches Lorsque les produits conformes aux exigences du présent document peuvent s’accoupler entre eux, le niveau résultant des performances de dispersion d’affaiblissement est conforme au Tableau 1. Le but est que cela se vérifie indépendamment de la ou des sources de fabrication du produit. Lorsque des variantes de fiche ayant différentes classes d’affaiblissement sont accouplées (comme spécifié dans l’EN 61755 1), le niveau d’affaiblissement qui en résulte ne peut pas être meilleur que celui de la classe d’affaiblissement la moins bonne des fiches individuelles. L’accouplement d’une fiche de classe C à une fiche de classe B aboutit à un niveau de classe C de performance de dispersion d'affaiblissement. Tableau 1 — Matrice de classe d’affaiblissement Classe fiche 1 Classe fiche 2 Classe d’affaiblissement assurée B B B C C C B C C C B C 1.3 Environnement de fonctionnement Les essais choisis, combinés avec les sévérités et les durées, sont représentatifs d’un environnement de catégorie C selon l’EN IEC 61753 1. 1.4 Fiabilité Alors que l'espérance de vie du produit prévue dans cet environnement est de 20 ans, la conformité à la présente norme ne garantit pas la fiabilité du produit. Celle-ci est estimée en utilisant un programme reconnu d'évaluation de la fiabilité. 1.5 Assurance de la qualité La conformité à la présente norme ne garantit pas l’uniformité de fabrication du produit. Il est prévu qu’elle soit maintenue en utilisant un programme reconnu d'assurance de la qualité.

1 Scope
1.1 Product definition
This document contains the initial, start of life, dimensional, optical, mechanical and environmental
performance requirements that an assembled single mode cord with cylindrical ferruled connectors will meet
in order for it to be categorized as an EN standard product.
Since different variants and grades of performance are permitted, product marking details are given in 4.5 and
Clause 5.
1.2 Intermateability of the plugs
Where the products conforming to the requirements of this document are intermateable, the resulting level of
random attenuation performance will be in accordance with Table 1. The intention is that this will be true
irrespective of the manufacturing source(s) of the product.
When intermating plug variants having different attenuation grades (as specified in EN 61755-1) the resulting
level of attenuation cannot be any better than the worst attenuation grade of the individual plugs.
Intermating a grade C plug with a grade B plug will result in a grade C level of random attenuation performance.

1.3 Operating environment
The tests selected, combined with the severities and durations, are representative of an EN IEC 61753-1
Category C environment.
1.4 Reliability
Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with
this standard does not guarantee the reliability of the product. This is predicted using a recognized reliability
assessment program.
1.5 Quality assurance
Compliance with this standard does not guarantee the manufacturing consistency of the product. This is
expected to be maintained using a recognized quality assurance program.
