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.
