IEC 60793-2:2003

Provides product specifications for coated optical fibres with or without buffer and deals with two classes of optical fibres, class A (multimode) and class B (single mode). There are at present four categories of class A fibres and three of class B. Applies to: · optical fibres type A1a, A1b, A1c and A1d which are used or can be incorporated in information transmission equipment and optical fibre cables; · optical fibres category A2 which are used and can be incorporated in short links in communication equipment or in cables for short-distance links (typically up to 2 km); · optical fibres category A3 which are used or can be incorporated in short links in communication equipment or in cables for short-distance links (typically up to 100 m); · optical fibres class B which are used or can be incorporated in information transmission equipment and optical fibre cables.

Contains the general requirements for both multimode and single mode optical fibres. Sectional specifications for each of the four multimode categories: A1, A2, A3, and A4 contain requirements specific to each category. The requirements of this standard apply to all categories. Each sectional specification contains the requirements that are common to all family specifications that are within it. Tests or measurement methods are defined for each specific attribute. This sixth edition cancels and replaces the fifth edition published in 2003. This modification has been necessary because of the addition of new fibre categories to IEC 60793-2-40, IEC 60793-2-50 and IEC 60793-2-60.
