Description (English):

IEC 61753-061-2:2020 contains the minimum test and measurement requirements and severities which a fibre optic isolator as specified by IEC 61202-1 satisfies in order to be categorized as meeting the requirements of isolators used in controlled environments as specified in IEC 61753-1. The requirements cover single-mode pigtailed style polarization independent isolators for category C used in controlled environments. This second edition cancels and replaces the first edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - addition of the detail high optical power test procedures and the condition in Annex B; - change of test conditions harmonizing with IEC 61753-1:2018; - addition of category CHD; - addition of the detailed measurements conditions in Annex C; - change of clause structure accordance with the latest ISO/IEC Directives, Part 2. The content of the corrigendum 1 (2025-05) has been included in this copy.

Abstract

Overview

IEC 61753-061-2:2020 is an IEC performance standard that specifies the minimum test and measurement requirements and severities for single‑mode fibre optic pigtailed polarization independent isolators intended for category C - controlled environments. It defines how non‑connectorized, single‑mode pigtail isolators (as specified by IEC 61202-1) should be prepared, tested and reported so they can be classified as meeting controlled‑environment performance. Edition 2.0 (2020) is a technical revision that also incorporates Corrigendum 1.

Key topics and requirements

Scope and sample preparation
- Applies to non‑connectorized, single‑mode, fibre‑pigtail style polarization independent isolators.
- Samples shall be terminated on single‑mode fibres per IEC 60793-2-50 and cable formats per IEC 60794-2-50.
Minimum tests and severities
- Test methods referenced from the IEC 61300 series (environmental, mechanical and optical test procedures).
- Includes examinations/measurements such as polarization dependence loss, attenuation/return loss, transient loss and polarization mode dispersion measurements in accordance with the referenced IEC procedures.
New/updated technical content (Edition 2)
- Annex B: detailed high optical power test procedures and conditions for forward, backward and bidirectional input tests.
- Harmonized test conditions with IEC 61753‑1:2018.
- Addition of category CHD and more detailed measurement conditions in Annex C.
- Clause structure updated per the latest ISO/IEC Directives.
Test reporting
- Requirements for sample size, test details and the format of test reports are specified (see Tables and Annex A).

Practical applications and users

Who uses IEC 61753-061-2:
- Fibre optic component manufacturers (qualification and production verification of pigtailed isolators).
- Independent test laboratories performing performance and environmental qualification.
- Procurement, OEMs and system integrators specifying isolators for indoor/controlled environments (data centers, central offices, lab equipment, optical amplifiers).
- Quality and reliability engineers ensuring components meet controlled‑environment performance classes.
Practical value:
- Ensures consistent, reproducible verification of isolator performance under mechanical, thermal, humidity and high optical power stress.
- Facilitates vendor comparisons and procurement specifications by standardizing test methods and severities.
