Applies to optical fibre types A3a, A3b, A3c and A3d. It covers requirements common to A3 multimode fibres. It also covers particular requirements for individual fibre types and specific applications. The main changes from the previous edition are: the addition of tensile strength requirement; the removal of water immersion requirement; and the addition of environmental requirements.

IEC 60793-2-30:2012 is applicable to sub-categories A3a, A3b, A3c, A3d and A3e. Three types of requirements apply to these fibres: - general requirements, as defined in IEC 60793-2; - specific requirements common to the category A3 multimode fibres covered in this standard and which are given in Clause 3; - particular requirements applicable to the individual sub-categories or specific applications (e.g. automotive or industrial applications), which are defined in the normative sub-category annexes. This third edition cancels and replaces the second edition, published in 2007. It constitutes a technical revision and includes the following significant technical changes with respect to the previous edition: - addition of a new sub-category A3e; - changed unit for core-cladding concentricity error and proof stress level. Keywords: A3 multimode fibres, sub-categories A3a, A3b, A3c, A3d and A3e
