EN 60793-2-40:2006

Optical fibres - Part 2-40: Product specifications - Sectional specification for category A4 multimode fibres

This part of IEC 60793-2 is applicable to optical fibre categories A4a, A4b, A4c, A4d, A4e, A4f, A4g and A4h. These fibres have a plastic core and plastic cladding and may have step-index, multi-step index, or graded-index profiles. The fibres are used in information transmission equipment and optical fibre cables.

Fibres optiques - Partie 2-40: Spécifications de produits - Spécification intermédiaire pour les fibres multimodales de catégorie A4

La présente partie de la CEI 60793-2 s'applique aux catégories de fibres optiques A4a, A4b, A4c, A4d, A4e, A4f, A4g et A4h. Ces fibres possèdent un c ur et une gaine en plastique et elles peuvent avoir un profil à saut d'indice, un profil à multi-saut d'indice ou un profil à gradient d'indice. Ces fibres sont utilisées dans les équipements de transmission de l'information et dans les câbles à fibres optiques.

This European Standard was approved by CENELEC on 2006-04-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, the Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 86A/1050/FDIS, future edition 2 of IEC 60793-2-40, prepared by SC 86A, Fibres
and cables, of IEC TC 86, Fibre optics, was submitted to the IEC-CENELEC parallel vote and was
approved by CENELEC as EN 60793-2-40 on 2006-04-01.
This European Standard supersedes EN 60793-2-40:2002. Main change is addition of Annexes E, F, G
and H that describe new fibres with lower attenuation reflecting the current state of the art.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2007-01-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2009-04-01
with the EN have to be withdrawn
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 60793-2-40:2006 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following note has to be added for the standard indicated:
IEC 60794-1-2 NOTE  Harmonized as EN 60794-1-2:2003 (not modified).
