IEC 60793-2-2015 光纤--第2部分：产品规范--总则 Optical fibres - Part 2: Product specifications - General

This part of IEC 60793 contains the general specifications for both multimode and single-
mode optical fibres. 
Sectional specifications for each of the four categories multimode fibres: A1, A2, A3, and A4
(part of the multimode fibre class A) contain requirements specific to each category. 
Sectional specifications for each of the two single-mode fibre classes, B and C, contain
requirements common to each class.
Each sectional specification includes family specifications (in normative annexes) that contain
requirements for the applicable category or sub-categories. These sub-categories are
distinguished on the basis of different fibre types or applications. 
The requirements of this standard apply to all classes. 
Each sectional specification contains the requirements that are common to all the family
specifications that are within it. These common requirements are copied to the family
specification for ease of reference.
Tests or measurement methods are defined for each specified attribute. Where possible,
these definitions are by reference to an IEC standard – otherwise the test or measurement
method is outlined in the relevant sectional specification.dition 8.0 2015-11 INTERNATIONAL STANDARD NORME INTERNATIONALE colour inside Optical fibres – Part 2: Product specifications – General Fibres optiques – Partie 2: Spécifications de produits – Généralités IEC 60793-2:2015-11(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2015 IEC, Geneva, Switzerland All rights reserved.
