This document provides a reliability qualification test template for dynamic modules (DMs). The template describes the reliability qualification test items and provides information on requirements or options. Example test conditions are given as information in Annex A.

For reliability qualification purposes, some information about the internal components, parts and interconnections is needed. These internal parts are treated as black boxes. This document gives requirements for the evaluation of DM reliability by combining the reliability of such internal black boxes.

The object of this reliability qualification test template is to provide a framework for the reliability qualification tests for DMs. Developers of reliability qualification tests for DMs determine the test conditions for each test item by referring to the examples in Annex A.

This part of IEC 60793 contains the general specifications for both multimode and single-mode optical fibres.

Sectional specifications for each of the four categories multimode fibres: A1, A2, A3, and A4 (part of the multimode fibre class A) contain requirements specific to each category.

Sectional specifications for each of the two single-mode fibre classes, B and C, contain requirements common to each class.

Each sectional specification includes family specifications (in normative annexes) that contain requirements for the applicable category or sub-categories. These sub-categories are distinguished on the basis of different fibre types or applications.

The requirements of this standard apply to all classes.

Each sectional specification contains the requirements that are common to all the family specifications that are within it. These common requirements are copied to the family specification for ease of reference.

Tests or measurement methods are defined for each specified attribute. Where possible, these definitions are by reference to an IEC standard – otherwise the test or measurement method is outlined in the relevant sectional specification.

Table 1 defines the sectional specifications. The relevant family specifications are defined within the sectional specifications as normative annexes (see Tables 2 to 5).

Annexes A and B summarize the existing fibre specifications.

This part of IEC 61754 family defines the standard connector interface dimensions for LSHE family of connectors with up to four termini. This connector family is targeting deployment
under harsh environmental conditions.

This part of International Standard IEC 60794 applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors.

The object of this standard is to define test procedures to be used in establishing uniform requirements for mechanical requirement performance.

Throughout the document the wording “optical cable” may also include optical fibre units, microduct fibre units, etc. 

See IEC 60794-1-2 for general requirements and definitions and for a complete reference guide to test methods of all types.

Numbering of the clauses containing test methods aligns with the clauses of IEC 60794-1-21, Ed. 1.

This part of IEC 60794-1 defines test procedures to be used in establishing uniform requirements for the environmental performance of

optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and

cables having a combination of both optical fibres and electrical conductors.

Throughout the standard the wording "optical cable" can also include optical fibre units, microduct fibre units, etc.

This part defines a test standard to determine the ability of a cable to withstand the effects of freezing water that can immediately surround the optical fibre cable sheath by observing any changes in the physical appearance of the sheath, or in the measured cable optical attenuation.

Method F15A is a test standard to simulate freezing of the medium surrounding a buried cable, as in wet earth or water. Method F15A is moved from Method F15 in IEC 60794-1-22, Ed. 2 without any technical changes.

Method F15B is a test standard to simulate freezing of the medium surrounding an outside cable in a conduit (duct) which is made of rigid material, e.g. steel.

See IEC 60794-1-2 for a reference guide to test methods of all types and for general requirements.

This part of IEC 60794 describes test procedures to be used in establishing uniform requirements for the geometrical, material, mechanical, environmental properties of optical fibre cable elements.

This document applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors.

Throughout the document, the wording “optical cable” can also include optical fibre units, microduct fibre units, etc.

See IEC 60794-1-2 for a reference guide to test methods of all types and for general requirements and definitions.

NOTE   The environmental testing of optical fibre ribbon would be valuable for some applications. Useful information about suitable test methods can be found in the fibre series IEC 60793-1-50 - 53.
