Full title and description

STB VDE 0888-120 E DIN EN 60794-2-50:2016-10 — Optical fibre cables — Part 2-50: Indoor optical fibre cables — Family specification for simplex and duplex cables for use in terminated cable assemblies. This is the German/adopted edition of the EN/IEC family specification addressing construction, mechanical and environmental test requirements for simplex and duplex indoor cables intended for use as terminated (pre-connectorised or patch) assemblies.

Abstract

This document provides a family specification defining requirements and test procedures for simplex and duplex indoor optical fibre cables used in terminated cable assemblies (patch leads, short interconnects and assembly-terminated links). It sets out mechanical, dimensional and environmental tests and references general IEC 60794 series clauses and relevant fibre and component standards. The 2016 German adoption has since been superseded by later EN/IEC revisions in the 2020–2023 timeframe.

General information

• Status: Withdrawn / superseded (German adoption of EN IEC 60794-2-50:2016 has been replaced by later EN/IEC editions).
• Publication date: 01 October 2016 (designation E DIN EN 60794-2-50:2016-10).
• Publisher: German adoption published as a DIN/EN document and issued in VDE-form (VDE 0888-120 designation for the German national foreword/version). VDE Verlag lists later consolidated VDE DIN EN IEC editions.
• ICS / categories: 33.180.10 (Fibre optics / optical fibre cables).
• Edition / version: German adoption E DIN EN 60794-2-50:2016-10 (VDE 0888-120 reference in national context).
• Number of pages: 37 (published German/adopted text).

Scope

The standard is a family specification that defines the types, constructional limits, and test requirements (mechanical and environmental) for simplex and duplex indoor optical fibre cables intended to be used as terminated cable assemblies or for termination of passive components. It is intended to be used alongside the general IEC 60794-1 series and other referenced fibre/component standards (e.g., IEC 60793 series) and is not intended to specify complete finished assemblies with their connector terminations in full detail.

Key topics and requirements

• Definition and identification of simplex and duplex indoor cable constructions and allowable dimensions.
• Mechanical tests: tensile (short-term and prolonged), torsion, bending and repeated bending, impact and crush tests with specified test conditions and acceptance criteria.
• Environmental tests: temperature (including low/high and cycling), humidity, thermal shock and shrinkage tests with category-specific limits; requirements reference applicable IEC test methods (e.g., IEC 60794-1-2 series).
• Shrinkage and dimensional stability limits (requirements and maximum allowable shrinkage values for indoor simplex/duplex cables).
• Requirements for reaction-to-fire / flame behaviour for indoor cables (descriptive requirements and references to applicable fire-performance standards or national regulations).
• Reference to fibre category and connector compatibility (linking to IEC 60793-2-50 fibre-category definitions used for terminated assemblies).
• Specified test sequence and reporting requirements for manufacturers, and normative references to related IEC/EN parts and test clauses.

Typical use and users

Intended users include fibre-cable manufacturers, cable-assembly fabricators (patch-cord and pigtail producers), test laboratories, telecommunications and data-centre engineers, and purchasing/specification teams that require standardised mechanical and environmental performance criteria for indoor simplex and duplex terminated cables. The family specification is commonly applied when specifying patch cords, short interconnect leads and factory-terminated assemblies.

Related standards

Typical related documents include IEC/EN 60794-1 series (general test methods and definitions), IEC 60793 series (fibre specifications, e.g., IEC 60793-2-50), other parts of IEC 60794 (construction and test specifications for other cable types such as 2-22, 2-21, etc.), and national/EN fire-performance standards for indoor cables. More recent consolidated editions of EN IEC 60794-2-50 (2020/2023) and VDE-adopted editions supersede the 2016 German adoption.

FAQ

Q: What is this standard?

A: It is the German-adopted EN/IEC family specification titled DIN EN 60794-2-50 (published as E DIN EN 60794-2-50:2016-10 and referenced nationally as VDE 0888-120) covering indoor simplex and duplex optical fibre cables intended for use as terminated cable assemblies.

Q: What does it cover?

A: It covers cable construction limits, dimensional criteria, and a suite of mechanical and environmental tests (tensile, torsion, bending, shrinkage, temperature, humidity, etc.), plus requirements for reporting and references to fibre and connector categories. It is a family/specification document intended to be used with IEC 60794-1 test methods and related IEC/EN references.

Q: Who typically uses it?

A: Cable and assembly manufacturers, test laboratories, procurement/spec writers for telecom and data-centre equipment, and installers specifying or verifying performance of terminated indoor simplex and duplex cables.

Q: Is it current or superseded?

A: The 2016 German-adopted edition is listed as withdrawn/superseded in national catalogs and has been replaced by later EN/IEC revisions (notably editions published in the 2020–2023 timeframe and consolidated VDE/DIN EN IEC editions). For current normative text the later EN IEC 60794-2-50 editions and the corresponding VDE/DIN publications should be consulted.

Q: Is it part of a series?

A: Yes — it is Part 2-50 of the IEC/EN 60794 series (the IEC 60794 family defines test methods and specifications for a wide range of optical fibre cable types; 2-50 is the family specification for indoor simplex/duplex terminated-use cables).

Q: What are the key keywords?

A: Indoor optical fibre cable, simplex, duplex, terminated assembly, patch cord, mechanical testing, environmental testing, VDE 0888-120, DIN EN 60794-2-50.
