Optical fibre cables - Part 1-133: Generic specifications - Basic optical cable test procedures - Mechanical test methods - Multiple cable coiling and uncoiling performance, Method E33

IEC 60794-1-133: 2025 defines the test procedure to demonstrate the ability of an optical fibre cable to withstand multiple coiling and uncoiling on a specified diameter of cable reel. This test is primarily intended to evaluate the performance of cables for mobile rapid or multiple deployment. See IEC 60794‑1‑2 for a reference guide to test methods of all types and for general requirements. This first edition of IEC 60794-1-133 cancels and replaces Method E33 of the second edition of the IEC 60794-1-21:2015/AMD1:2020, which will be withdrawn. It includes an editorial revision, based on the new structure and numbering system for optical fibre test methods.

Overview - EN IEC 60794-1-133:2025 (Method E33)

EN IEC 60794-1-133:2025 (IEC 60794-1-133:2025) defines Method E33: Multiple cable coiling and uncoiling performance for optical fibre cables. The standard specifies a non‑destructive test procedure to demonstrate a cable’s ability to withstand repeated coiling and uncoiling on a specified cable‑reel diameter. It is primarily intended to evaluate cables used for mobile, rapid or multiple deployments where reels used in the field may have significantly different core diameters than transport reels. This first edition replaces Method E33 from IEC 60794-1-21:2015/AMD1:2020 and aligns test numbering with the new IEC 60794‑1‑1xx structure.

Key topics and technical requirements

• Objective: Assess changes in optical attenuation and detect physical damage caused by multiple coiling/uncoiling cycles on a defined reel diameter.
• Non‑destructive testing: Method E33 is designed to preserve the cable while evaluating performance.
• Test components: Defined sample selection, apparatus, procedural steps, and pass/fail requirements are specified (see clauses on sample, apparatus, procedure and requirements).
• Measurement focus: Monitoring of attenuation changes (referenced to IEC 60793‑1‑46) and inspection for physical damage after cycling.
• Documentation: The standard requires details to be specified by the test sponsor and details to be reported by the tester; an informative Annex A provides practical test‑set examples (e.g., uncoiling from transport reel, cut sample on test reel).
• Traceability: Cross‑references to IEC 60794‑1‑1 and IEC 60794‑1‑2 for general guidance and other basic optical cable test procedures.

Practical applications - who uses this standard

• Cable manufacturers: Validate cable designs for deployable applications (portable links, temporary networks, emergency response).
• Test laboratories and certification bodies: Provide repeatable test methods for product qualification and compliance reporting.
• Network operators and system integrators: Specify acceptance criteria and procurement requirements for mobile deployment cables.
• R&D teams: Evaluate design changes impacting reel handling, mechanical resilience and optical performance under repeated deployment conditions.

Related standards and keywords

• Related: IEC 60793‑1‑46 (attenuation monitoring), IEC 60794‑1‑1 (general), IEC 60794‑1‑2 (test guidance).
• SEO keywords: optical fibre cables, multiple coiling and uncoiling, cable reel performance, Method E33, EN IEC 60794‑1‑133:2025, optical cable test procedures, mechanical test methods, attenuation monitoring.

This standard helps ensure repeatable, documented evaluation of deployable optical cables-critical for reliable temporary and mobile fibre deployments.

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be o
