scope:

This part of IEC 60793-2 is applicable to optical fibre types A3a, A3b, A3c, and A3d. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables (typically up to 1 km).

Three types of requirements apply to these fibres:

- general requirements, as defined in IEC 60793-2;

- specific requirements common to the category A3 multimodal fibres covered in this standard and which are given in Clause 3;

- particular requirements applicable to individual fibre types or specific applications (e.g. automotive or industrial applications), which are defined in the normative family specification annexes.
