This part of IEC 60793 is applicable to optical fibre types B1.1, B1.2, B1.3, and categories B2,
B4, B5 and B6. A map illustrating the connection of IEC designations to ITU-T designations is
shown in Annex I. These fibres are used or can be incorporated in information transmission
equipment and optical fibre cables.
Three types of requirements apply to these fibres:
~ general requirements, as defined in IEC 60793-2;
~ specific requirements common to the class B single-mode 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 Annexes A to G.
~ For some family specifications, there are sub-categories that are distinguished on the
basis of difference in transmission attribute specifications. The designations for these sub-
categories are documented in the individual family specifications.
