Full title and description

Fibre optic interconnecting devices and passive components - Fibre optic circulators - Generic specification. IEC 62077:2022 defines generic requirements, classification, documentation and quality‑assessment procedures for passive, non‑reciprocal fibre‑optic circulators with three or more ports; it is published in English and French (bilingual).

Abstract

IEC 62077:2022 (Edition 4.0) is the fourth edition of the international generic specification for fibre‑optic circulators. It updates and harmonizes terminology and normative requirements for passive, non‑reciprocal devices whose ports are optical fibres or fibre connectors, and provides requirements for design, performance, documentation and quality assessment. Informative annexes give an example of circulator technology and an example application. This edition cancels and replaces the previous edition and introduces technical revisions including harmonization with relevant vocabulary Technical Specifications and changes to Clause 4 (requirements).

Scope

IEC 62077:2022 applies to circulators used in the field of fibre optics that meet all the following characteristics: they are non‑reciprocal optical devices in which each port is an optical fibre or fibre‑optic connector; they are passive devices (as categorized in IEC TS 62538); and they have three or more ports for directional transmission of optical power. The standard addresses classification, documentation, performance and quality assessment and includes informative annexes describing an example circulator technology and an example application.

Key topics and requirements

• Definitions and harmonized vocabulary for passive fibre‑optic circulators (aligned with relevant IEC technical specifications).
• Classification and assessment levels (type, style, variants, assessment/quality levels).
• Documentation and specification system requirements (drawings, symbols, test and measurement reporting, instructions for use).
• Design, construction and materials guidance, including workmanship and marking/identification requirements.
• Performance parameters and test requirements (insertion loss, isolation, return loss, polarization effects and other performance characteristics as applicable).
• Quality assessment and sampling/test procedures for conformity and production control.
• Environmental, storage and packaging considerations relevant to device reliability and transport.
• Informative annexes: example magneto‑optic circulator technology and example applications (illustrative, non‑normative).
• Harmonization changes introduced in the 2022 edition (including alignment with IEC TS 62627‑09 and updates to Clause 4 requirements).

Typical use and users

Primary users include fibre‑optic component manufacturers (design, production and quality teams), test laboratories and conformity assessors, system integrators and equipment vendors specifying or using circulators in WDM systems, optical add/drop and bidirectional links, sensing applications and amplifier/isolation functions, and procurement or standards teams preparing specifications for interoperability and acceptance tests.
