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, which are defined in the normative family specification annexes.
