Optical fibre - Part 2-70: Product specifications - Sectional specifications for polarization-maintaining fibres (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.

IEC 60793-2-70:2017 La présente partie de l’IEC 60793 est applicable aux fibres optiques de type D1, D2, D3, comme décrit dans le Tableau 1. Ces fibres sont des fibres à maintien de polarisation, elles sont utilisées ou peuvent être intégrées dans des équipements destinés à la transmission de l’information et dans des câbles à fibres optiques. Ces fibres sont disponibles afin d’être utilisées au sein de réseaux de transport optique. Trois types d’exigences s’appliquent à ces fibres:

   
• les exigences générales, définies dans l’IEC 60793-2;

   
• des exigences spécifiques communes aux fibres à maintien de polarisation de catégorie D couvertes par le présent document et qui sont données à l’Article 4;

   
• des exigences particulières applicables à des types particuliers de fibres ou à des applications données, qui sont définies dans les Annexes A à C.

Part 2-70: Product specifications –
Sectional specification for polarization-maintaining fibres

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 the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60793-2-70 has been prepared by subcommittee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.
The text of this International Standard is based on the following documents:
CDV Report on voting

Part 2-70: Product specifications –
Sectional specification for polarization-maintaining fibres



1 Scope
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 This category of polarization-maintaining fibre is
suitable for use at 980 nm optimised for polarization-maintaining ability in the
980 nm region. This fibre is used for erbium-doped
fibre amplifier.
D2 Polarization-maintaining fibre This category of polarization-maintaining fibre is
suitable for use at 1 310 nm optimised for polarization-maintaining ability and
connection property of category B fibres in the
1 310 nm region.
D3 Polarization-maintaining fibre This category of polarization-maintaining fibre is
suitable for use at 1 550 nm optimised for polarization-maintaining ability and
connection property of category B fibres in the
1 550 nm region.
