This part of IEC 60793 is applicable to optical fibre categories B1.1, B1.2, B1.3, 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 5;
-
particular requirements applicable to individual fibre categories or specific applications, which are defined in Annexes A to G.
For some fibre categories (shown in the relevant family specifications), there are subcategories 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.
