IEC 60793-2-20-2015 pdf free download.Optical fibres – Part 2-20: Product specifications – Sectional specification for category A2 multimode fibres.
This part of IEC 60793 is applicable to sub-categories A2a, A2b, and A2c. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables (typically up to 2 km).
Three types of requirements apply to these fibres:
• general requirements as defined in IEC 60793-2;
• specific requirements common to the category A2 multimodal fibres covered in this standard and which are given in Clause 3;
• particular requirements applicable to individual sub-categories or specific applications, which are defined in the normative family specification annexes.
