Overview

EN IEC 61753-085-02:2021 - Fibre optic interconnecting devices and passive components - Performance standard - Part 085-02: Non-connectorized single-mode pigtailed CWDM devices for category C (indoor controlled environment) - specifies the minimum initial test and measurement requirements and severities required to classify pigtailed coarse wavelength division multiplexing (CWDM) devices as Category C (indoor controlled environment). This edition (2021) replaces the 2008 version and harmonizes test conditions with IEC 61753-1:2018. CWDM terminology follows IEC 62074‑1.

Key topics and technical requirements

The standard focuses on practical, repeatable test and measurement regimes for non-connectorized single-mode pigtailed CWDM devices. Main technical topics include:

• Scope and classification: criteria to be categorised as Category C (indoor controlled environment).
• Test matrix and severities: minimum initial tests and required pass/fail severities (test details reported in the document).
• Test procedures referenced: harmonized use of the IEC 61300 series for basic tests and measurements, including:
  • Vibration (sinusoidal)
  • Fibre/cable retention and strain-relief tests
  • Torsion and shock
  • Temperature and humidity endurance (cold, dry heat, damp heat, change of temperature)
  • Static side load and flexing of strain relief
  • High optical power exposure
  • Optical performance measurements (polarization dependent loss, return loss, wavelength dependence, spectral transfer)
• Sample size, dimensions and reporting: requirements for sample grouping, test report contents and performance criteria are specified (without numerical values in this summary).

Practical applications

EN IEC 61753-085-02:2021 is used to ensure consistent quality and predictable field performance of pigtailed CWDM devices in controlled indoor environments such as:

• Data centers, central offices and telecommunications rooms
• Indoor fiber distribution panels and patching systems
• Passive optical modules integrated into equipment racks

Who benefits:

• Manufacturers of non-connectorized single‑mode pigtailed CWDM modules (design, QA, production)
• Independent test laboratories performing conformance and reliability testing
• Procurement and specification engineers writing product requirements for indoor deployments
• System integrators and network planners validating component suitability for Category C environments

Related standards

• IEC 61753-1:2018 - General performance standard and guidance
• IEC 62074-1 - Generic specification for fibre optic WDM devices (CWDM definition)
• IEC 61300 series - Basic test and measurement procedures (vibration, retention, temperature, optical tests)
• IEC 60793-2-50 / IEC 60794-2-50 - Optical fibre and indoor cable product specifications

Using EN IEC 61753-085-02:2021 helps manufacturers and buyers standardize test methods, reduce deployment risk, and demonstrate compliance for pigtailed CWDM components in indoor controlled environments.

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.
IEC 61753-085-02 has been prepared by subcommittee 86B: Fibre optic interconnecting
devices and passive components, of IEC technical committee 86: Fibre optics. It is an
International Standard.
This first edition cancels and replaces IEC 61753-085-2 published in 2008. This edition
constitutes a technical revision.
This edition includes the following specific technical change with respect to IEC 61753-085-2:
change of test conditions harmonizing with IEC 61753-1:2018.
