Optical fibres - Part 2-70: Product specifications - Sectional specification for polarization-maintaining fibres
This part of IEC 60793 is applicable to optical fibre types D1, D2, D3, as described in Table 1. These fibres are polarization-maintaining fibre types, and are used or can be incorporated in information transmission equipment and optical fibre cable. These fibres are available for use in optical transport networks. Three types of requirements apply to these fibres: - general requirements defined in IEC 60793-2; - specific requirements common to the category D polarization-maintaining fibres covered in this document and which are given in Clause 4; - particular requirements applicable to individual fibre types or specific applications, which are defined in Annexes A to C.

Ta vlakna so na voljo za uporabo v optičnih transportnih omrežjih. Za ta vlakna veljajo tri vrste zahtev:
– splošne zahteve, opredeljene v standardu IEC 60793-2;
– posebne zahteve, ki so skupne vlaknom, ki ohranjajo polarizacijo, kategorije D iz tega dokumenta in so navedene v točki 4;
– posebne zahteve, ki veljajo za posamezne vrste vlaken ali posebne načine uporabe in so opredeljene v dodatkih od A do C.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with
