Overview

IEC 61753-382-2:2015 is an international performance standard published by the International Electrotechnical Commission (IEC). This standard specifies minimum initial performance, test, and measurement requirements for non-connectorized single-mode bidirectional fibre optic WWDM devices designed for wide wavelength division multiplexing in Gigabit-capable Passive Optical Networks (G-PON) and Next Generation Access (NGA) systems. It covers the category C classification, which applies to devices used in controlled environments. IEC 61753-382-2:2015 ensures device reliability and performance for critical telecommunications applications, aligning with IEC 61753-1:2007 requirements.

Key Topics

• Non-connectorized WWDM Devices: The standard focuses on non-connectorized (pigtailed) single-mode bidirectional devices that combine and split G-PON upstream/downstream signals along with NGA wavelength bands.
• Category C - Controlled Environment: Devices categorized under category C are intended for environments with controlled temperature, humidity, and other parameters, as defined in IEC 61753-1 Annex A.
• Performance and Test Requirements: Defines testing procedures including vibration, shock, temperature cycling, high optical power endurance, and optical performance such as insertion loss and wavelength-dependent characteristics.
• Normative References: Relies on related IEC standards such as IEC 61300 series for basic fiber optic device testing and IEC 60793-2-50 for single-mode fiber specifications.
• Wavelength Ranges: Specifies operational wavelength ranges for WWDM devices under G-PON NGA applications consistent with ITU-T G.984.5 recommendations.
• Test Report Structure: Includes defined sample size, test methods, and detailed requirement tables to ensure conformity and reproducibility.

Applications

IEC 61753-382-2:2015 standard is essential for manufacturers and users of fibre optic components in:

• Telecommunication Networks: Particularly in the deployment and maintenance of gigabit passive optical networks requiring reliable multiplexing of G-PON and NGA signals.
• Next Generation Access (NGA) Services: Supports higher bandwidth and advanced services through NGA wavelength bands integration.
• Controlled Environment Installations: Suitable for indoor or environmentally regulated telecom equipment rooms, data centers, and network hubs.
• Passive Optical Network (PON) Components Quality Assurance: Provides criteria for product qualification, acceptance testing, and supplier compliance for non-connectorized WWDM devices.

By adhering to IEC 61753-382-2, network providers and component manufacturers ensure improved device interoperability, performance consistency, and reliability under controlled environmental conditions, critical for modern high-speed optical networks.

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.

Figure B.1 – Sample of the wavelength dependence
of insertion loss of a G-PON-NGA WDM device
The G-PON-NGA WDM is used inside the optical network for combining and separating the G-
PON up/down signals and the NGA bands as shown in Figures B.2 to B.7. Wavelengths inside
the Figures B.2 to B.7 for simpler representation are printed without units (the unit is
nanometer (nm)). Depending on the complexity of the required function the G-PON-NGA
WDM is used in combination with another WDM.
