Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-39: Examinations and measurements - Physical contact (PC) optical connector reference plug selection for return loss measurements (IEC 61300-3-39:2011)

IEC 61300-3-39:2011 selects non-angled physical contact (PC) optical connector plugs for use as the reference plug in the return loss RL measurement and to define an acceptance return loss value RL_a for use in plug acceptance testing. This procedure is for use to guarantee a certain return loss value RL when two plugs have been successfully tested against the reference connector when randomly mated. This second edition of IEC 61300-3-39 cancels and replaces the first edition published in 1997 and constitutes a technical revision. Changes from the previous edition are structure of the standard, general description and the Annex.

La CEI 61300-3-39:2011 l'objectif est de choisir des fiches sans angle pour connecteurs optiques à contact physique (PC) destinées à être utilisées comme fiches de référence lors de la mesure de l'affaiblissement de réflexion (RL) et de définir une valeur d'affaiblissement de réflexion d'acceptation, RL_a, à utiliser dans les essais d'acceptation de fiches. Cette procédure est utilisée pour garantir une certaine valeur d'affaiblissement de réflexion RL lorsque deux fiches ont satisfait aux essais par rapport au connecteur de référence lorsqu'elles sont accouplées de manière aléatoire. Cette seconde édition de la CEI 61300-3-39 annule et remplace la première édition publiée en 1997; elle constitue une révision technique. Les changements par rapport à l'édition précédente concernent la structure de la norme, la description générale et l'Annexe.

Cilj tega dela standarda IEC 61300 je izbrati nepoševne vtiče za optični konektor s fizičnim kontaktom (PC), ki se uporabljajo kot referenčni vtiči za meritve povratnih izgub (RL), in določiti sprejemljivo vrednost povratne izgube (RLa) za uporabo pri preskušanju sprejemljivosti vtiča. Ta postopek se uporablja za zagotovitev določene vrednosti povratne izgube (RL), če sta bila dva vtiča uspešno preskušena z referenčnim konektorjem, pri čemer sta bila naključno izbrana.

Overview

EN 61300-3-39:2012 (CLC adoption of IEC 61300-3-39:2011) is a technical standard for fibre optic interconnecting devices and passive components that specifies procedures for selecting physical contact (PC) optical connector reference plugs used in return loss (RL) measurements. It applies to non‑angled PC plugs and defines how to choose a reference plug and set an acceptance return loss (RLa) for plug acceptance testing so that two randomly mated plugs will meet a minimum RL requirement.

This edition supersedes EN 61300-3-39:1997 and includes structural and descriptive revisions and an updated annex.

Key topics and requirements

• Reference plug selection: A reference plug is chosen from a group (minimum three) such that all pairwise matings among the group produce return loss within a specified range. The standard gives an operative method for selecting these plugs.
• Acceptance return loss (RLa): EN 61300-3-39 defines how to compute an acceptance limit RLa for a plug under test based on the reference plug return loss (RLref) and the measured result (RLm). This ensures guaranteed minimum RL when two random plugs are mated.
• Measurement procedure: Procedures cover mating schemes, measurement sequence and apparatus considerations for accurate RL assessment when testing plugs against the reference.
• Accuracy and specification details: The standard addresses accuracy considerations and lists the details that must be specified in test and product documentation (e.g., RLref value and tolerance).
• Informative annex: Provides background on physical mechanisms (surface damage layers, refractive index effects) that cause return loss in PC connectors and practical measurement guidance.

Practical applications

• Ensuring consistent optical performance of connectorized fibre assemblies in manufacturing and quality control.
• Defining acceptance criteria for connector plugs used in telecom, datacom, and fiber‑to‑the‑premises (FTTP) equipment.
• Establishing a repeatable return loss measurement methodology for suppliers, test labs and OEMs who need to guarantee mating performance of PC connectors.
• Supporting interoperability testing where minimum random‑mated RL performance must be guaranteed.

Who should use this standard

• Test laboratories performing connector qualification and production acceptance.
• Manufacturers of PC optical connectors and fibre optic transceivers.
• Quality engineers and compliance teams in telecom and datacom sectors.
• System integrators and designers specifying connector RL requirements.

• IEC/EN 61300-3-6 - Part 3-6: Examinations and measurements - Return loss (normative reference).

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 61300-3-39 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This second edition of IEC 61300-3-39 cancels and replaces the first edition published in
1997 and constitutes a technical revision. Changes from the previous edition are structure of
the standard, general description and the Annex.
