DIN EN 60793-2-20:2016-10

This part of the IEC 60793-2 series 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. This standard differs from DIN EN 60793-2-20 (VDE 0888-322):2010-01 as follows: a) NA has been replaced by NA; b) the test length of the test specimen and measurement details for the characteristic diameter and NA have been specified. The responsible committee is DKE/UK 412.6 "Lichtwellenleiter und Lichtwellenkabel" ("Optical fibres and fibre cables") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
