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: ?C general requirements@ as defined in IEC 60793-2; ?C specific requirements common to the class B single-mode fibres covered in this standard and which are given in Clause 3; ?C 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.
