IEC 60869-1:2018

Overview

IEC 60869-1:2018 is the fifth edition of the IEC generic specification for fibre optic passive power control devices. It defines generic requirements, terminology and documentation for passive two‑port optical devices that do not contain optoelectronic or transducing elements. Covered device classes include optical attenuators (fixed and variable/VOA), optical fuses, and optical power limiters. Ports may be non‑connectorized pigtails, connectorized fibres or receptacles. This edition updates terms and definitions, reviews the IEC Quality Assessment System, removes the clause on quality assessment procedures and adds Annex G with technical information on variable optical attenuator technologies.

Key Topics

• Scope and definitions: clear terminology for component and performance characteristics, aligned with the IEC 61753‑05x series.
• Device description: functional operation curves for fixed attenuators, VOAs, optical fuses and power limiters.
• Classification and identification: requirements for type, wavelength band, style, variant and assessment levels.
• Performance and tests: documentation of required tests, measurements, test data sheets and performance criteria for insertion loss, attenuation range, response time and stability (see normative references for test methods).
• Design, materials and workmanship: construction, marking, packaging, storage and safety requirements relevant to passive optical components.
• Documentation and specification system: three‑level IEC specification structure including drawings, instructions for use and test reports.
• Annex G (new): example technologies for VOAs such as MEMS, PLC/thermo‑optic and magnet‑optic approaches (informative).

Applications and Users

Practical uses of IEC 60869‑1:2018 include:

• Specifying and qualifying components for telecommunications and data communications networks.
• Selection and procurement of fixed and variable attenuators for link power balancing and laboratory measurement.
• Integration of optical fuses and power limiters for system protection against high optical power, transients or laser hazards in CATV, enterprise and industrial optics.
• Guiding manufacturers, test laboratories, system integrators and procurement teams on documentation, marking and conformance expectations.

Who should use this standard:

• Component manufacturers preparing product datasheets and test plans.
• Quality and compliance engineers validating optical passive power control devices.
• Test labs performing IEC‑referenced measurements.
• System designers and procurement specialists specifying components for optical links.
