This part of IEC 60793 contains the general specifications for both multimode and single-mode optical fibres.
Sectional specifications for each of the four categories of multimode fibres: A1, A2, A3, and A4 (part of the multimode fibre class A) contain requirements specific to each category.
Sectional specifications for each of the three single-mode fibre classes, B, C and D contain requirements common to each class.
Each sectional specification includes family specifications (in normative annexes) that contain requirements for the applicable category or sub-categories. These sub-categories are distinguished on the basis of different fibre types or applications.
The requirements of this document apply to all classes.Cross References:IEC 60304IEC 60793-1HD 402 S2IEC 60793-1 (all parts)EN 60793-1IEC 60793-2-40:2015EN IEC 60793-2-10:2019IEC 60793-2-50:2018EN 60793-2-40:2016EN 60793-2-70:2017EN 60793-2-20:2016IEC 60793-2-20:2015EN 60793-2-60:2008IEC 60793-2-60:2008EN 60793-2-30:2015IEC 60793-2-10:2019IEC 60793-2-70 Ed.1.0EN IEC 60793-2-50:2019IEC 60793-2-30 Ed.4.0IEC 60050-731:1991All current amendments available at time of purchase are included with the purchase of this document.
