Annotation of standard text IEC 60793-2-70-ed.1.0 :

IEC 60793-2-70: 2017 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. Table 1 – Categories of glass core/glass clad polarization-maintaining fibres

Category Type Description
D1 Polarization-maintaining fibre suitable for use at 980 nm This category of polarization-maintaining fibre is optimised for polarization-maintaining ability in the 980 nm region. This fibre is used for erbium-doped fibre amplifier.
D2 Polarization-maintaining fibre suitable for use at 1 310 nm This category of polarization-maintaining fibre is optimised for polarization-maintaining ability and connection property of category B fibres in the 1 310 nm region.
D3 Polarization-maintaining fibre suitable for use at 1 550 nm This category of polarization-maintaining fibre is optimised for polarization-maintaining ability and connection property of category B fibres in the 1 550 nm region.
IEC 60793-2-70:2017 La presente partie de l’IEC 60793 est applicable aux fibres optiques de type D1, D2, D3, comme decrit dans le Tableau 1. Ces fibres sont des fibres a maintien de polarisation, elles sont utilisees ou peuvent etre integrees dans des equipements destines a la transmission de l’information et dans des cables a fibres optiques. Ces fibres sont disponibles afin d’etre utilisees au sein de reseaux de transport optique. Trois types d’exigences s’appliquent a ces fibres: Tableau 1 – Categories de fibres a maintien de polarisation a cour en verre/gaine en verre
Categorie Type Description
D1 Fibre a maintien de polarisation convenant a un usage a 980 nm. Cette categorie de fibres a maintien de polarisation est specialement concue pour le maintien de la polarisation autour de 980 nm. Cette fibre est utilisee pour les amplificateurs a fibre dopee a l’erbium.
D2 Fibre a maintien de polarisation convenant a un usage a 1 310 nm. Cette categorie de fibres a maintien de polarisation est specialement concue pour le maintien de la polarisation et pour les proprietes de connexion des fibres de la categorie B autour de 1 310 nm.
D3 Fibre a maintien de polarisation convenant a un usage a 1 550 nm. Cette categorie de fibres a maintien de polarisation est specialement concue pour le maintien de la polarisation et pour les proprietes de connexion des fibres de la categorie B autour de 1 550 nm.
