Full title and description

Fibre optic interconnecting devices and passive components - Performance standard - Part 091-02: Non-connectorized 3-port incompletely circulated single-mode fibre optic circulators for category C - Controlled environments. This document specifies minimum test and measurement requirements and severities for non-connectorized, 3‑port, incompletely circulated single‑mode fibre optic circulators intended for use in controlled (category C) environments.

Abstract

This first edition of IEC 61753-091-02:2022 provides the performance testing framework required to classify non‑connectorized 3‑port incompletely circulated single‑mode circulators as meeting category C controlled‑environment requirements. It harmonizes terms, test items and conditions with related IEC documents (including IEC 62077, IEC 61753-1:2018 and relevant amendments/technical specifications) and replaces the earlier 2012 publication.

Scope

The standard contains minimum test and measurement requirements and severities for non‑connectorized single‑mode fibre optic 3‑port incompletely circulated circulators intended for category C (controlled) environments. It applies to devices specified by IEC 62077 and is intended to allow manufacturers, test laboratories and purchasers to determine if a circulator meets the environmental and performance classification criteria of IEC 61753‑1 (including relevant amendments). The scope targets performance verification rather than design details.

Key topics and requirements

• Definition and classification of non‑connectorized 3‑port incompletely circulated single‑mode fibre optic circulators.
• Minimum test procedures and measurement methods for insertion loss, isolation, return loss and other optical parameters relevant to circulator performance.
• Environmental and mechanical test severities aligned with IEC 61753‑1:2018 and its amendment(s) for category C controlled environments.
• Harmonized terminology and test item definitions consistent with IEC 62077 and related IEC technical specifications.
• Guidance for classification and reporting of test results to support procurement and qualification.

Typical use and users

Primary users include fibre‑optic component manufacturers, qualification and test laboratories, procurement officers in telecommunications and datacom equipment suppliers, and R&D teams responsible for component verification. The standard is used to produce test reports for product data sheets, to qualify production lots, and to support contractual acceptance of circulators intended for controlled environments.

Related standards

Key related documents include IEC 61753‑1 (general performance standard and environmental categories), IEC 62077 (specification of fibre optic circulators), IEC TS 62627‑09 and IEC 61977 (harmonized terminology and complementary test methods). The 2022 edition replaces IEC 61753‑091‑2:2012.

FAQ

Q: What is this standard?

A: IEC 61753-091-02:2022 is an international performance standard that defines minimum test and measurement requirements for non‑connectorized 3‑port incompletely circulated single‑mode fibre optic circulators intended for category C (controlled) environments.

Q: What does it cover?

A: It covers classification, required tests and severities, and reporting criteria for key optical and environmental performance parameters (e.g., insertion loss, isolation, return loss and environmental stress tests) for the specified circulator type. It harmonizes test items with IEC 61753‑1 and references IEC 62077 for device specification.

Q: Who typically uses it?

A: Manufacturers of fibre optic circulators, independent test/qualification laboratories, procurement and quality engineers in telecom/datacom sectors, and standards specialists who need to verify component conformance for controlled environments.

Q: Is it current or superseded?

A: This is the current edition published 16 February 2022; it cancels and replaces the earlier IEC 61753-091-2:2012. Users should verify whether any amendments or corrigenda have been published since 2022 before relying on the document for formal procurement or certification.

Q: Is it part of a series?

A: Yes — it is part of the IEC 61753 series of performance standards for fibre optic interconnecting devices and passive components; this part (091‑02) addresses a specific circulator type and environment category.

Q: What are the key keywords?

A: fibre optic circulator, non-connectorized, incompletely circulated, 3‑port, single‑mode, performance standard, controlled environment, category C, IEC 61753, IEC 62077.
