Full title and description

IEC 61753-071-02:2020+AMD1:2024 — Fibre optic interconnecting devices and passive components — Performance standard — Part 071-02: Non-connectorized single-mode fibre optic 1 × 2 and 2 × 2 spatial switches for category C (controlled environments). This publication is the 2020 edition consolidated with Amendment 1 issued in 2024 and defines the minimum initial tests, measurement requirements and severity levels for classifying non‑connectorized 1×2 and 2×2 single‑mode spatial switches for controlled environments.

Abstract

This consolidated publication specifies performance requirements and test procedures (including updated requirements introduced by Amendment 1, 2024) for non‑connectorized single‑mode 1×2 and 2×2 spatial optical switches intended for Category C — controlled environments. The document includes requirements for repeatability and switching durability, revised switching‑time criteria, updated high‑optical‑power test conditions and harmonization with IEC 61753‑1:2018.

Scope

This standard establishes the minimum initial test and measurement requirements and severities that non‑connectorized single‑mode 1×2 and 2×2 spatial switches must satisfy to be classified as Category C (controlled environments) under the IEC 61753 series. It updates and replaces the 2014 version of the same part, aligning test conditions with IEC 61753‑1:2018 and adding or revising specific performance and test criteria.

Key topics and requirements

• Definition of product scope: non‑connectorized single‑mode 1×2 and 2×2 spatial optical switches for Category C (controlled environments).
• Minimum initial test and measurement requirements and severity levels for Category C classification.
• Added performance requirements for repeatability and switching durability (introduced by Amendment 1, 2024).
• Removal of certain requirements/tests (example: directivity performance requirement and operational shock test removed by the amendment).
• Revised switching‑time requirements and modified high optical power test conditions.
• Harmonization of test conditions and terminology with IEC 61753‑1:2018.

Typical use and users

Applied by manufacturers of optical switches and passive fibre‑optic components, qualification and test laboratories, procurement and quality teams in telecommunications and datacom equipment vendors, product designers and system integrators who require objective performance classification for controlled‑environment optical switching components. The standard is used to specify acceptance test plans, supplier requirements and product datasheet performance limits.

Related standards

Primary related documents include IEC 61753‑1 (general classification and environmental categories, e.g. Category C) and other parts of the IEC 61753 series covering connectorized and other device types. The 2024 amendment has been adopted/endorsed by regional/national bodies (for example as UNE‑EN IEC 61753‑071‑02:2020/A1:2024 and corresponding national editions).

FAQ

Q: What is this standard?

A: IEC 61753‑071‑02 (consolidated with AMD1:2024) is a performance test and classification standard for non‑connectorized single‑mode 1×2 and 2×2 spatial optical switches intended for controlled environments (Category C). It defines the required tests, severities and performance limits for classification.

Q: What does it cover?

A: It covers minimum initial test and measurement requirements, specific performance criteria (including repeatability and switching durability), and test conditions (including switching time and high optical power tests) used to determine conformity to Category C of the IEC 61753 series. The 2024 amendment introduced the notable technical changes.

Q: Who typically uses it?

A: Manufacturers of optical switches, test laboratories, procurement and quality engineers in telecom/datacom, product designers, and system integrators who need standardized performance classification for non‑connectorized spatial switches.

Q: Is it current or superseded?

A: The consolidated edition incorporating Amendment 1 (published 23 February 2024) is the current published version; it updates and replaces the earlier 2014/2020 baseline for this part. The consolidated publication lists a stability date toward 2026.

Q: Is it part of a series?

A: Yes — it is one part of the IEC 61753 series (Product performance standards and classification for fibre‑optic interconnecting devices and passive components), and should be used together with IEC 61753‑1 (general classification and environmental categories) and other part‑specific documents in the series.

Q: What are the key keywords?

A: fibre optic; non‑connectorized; spatial switch; 1×2; 2×2; single‑mode; performance test; Category C; repeatability; switching durability; IEC 61753.
