IEC 60793-1-1:2022

Overview

IEC 60793-1-1:2022 - "Optical fibres - Part 1-1: Measurement methods and test procedures - General and guidance" is the general guidance document that lists and explains the uniform measurement and test documents used across the IEC 60793 series. Its primary purpose is to assist inspection and acceptance of optical fibres and cables for commercial (mainly telecommunications) use by providing a harmonized framework for measurement methods, test procedures, and reporting.

This fifth edition (2022) replaces the 2017 edition and constitutes a technical revision. Notable changes include updated normative references and a renamed Clause 10 with added documentation requirements (new subclause 10.2).

Key Topics

• Scope and applicability: Guidance for use of the IEC 60793-1‑X parts; generally applies to class A multimode and class B/C single-mode fibres specified in IEC 60793-2 (with possible exceptions).
• Measurement and test categories: Parameter measurements, performance measurements, and compliance tests - grouped by dimensions, mechanical, optical/transmission, environmental, and polarization-maintaining tests.
• Normative references and terms: References other parts of IEC 60793 and terminology from IEC TR 61931.
• Rounding rules: Specifies conventional rounding rule ("rounding half away from zero") for reported results to ensure consistent acceptance decisions.
• Standard atmospheric conditions: Defines standard laboratory ambient conditions (for example, temperature 23 °C ± 5 °C) and refers to Table 1 for full ranges to ensure comparability of results between labs.
• Calibration and reference methods: Guidance on calibration, reference test methods and traceability to support measurement reproducibility.
• Packaging and documentation: Requirements for packaging and, in the 2022 edition, extended documentation-related requirements for test reports and delivery documentation.

Applications and Users

IEC 60793-1-1:2022 is essential for:

• Optical fibre and cable manufacturers (quality control and product acceptance)
• Independent test laboratories and calibration facilities
• Network operators and procurement teams verifying supplier claims
• Certification bodies assessing conformity to IEC product specifications
• R&D groups developing optical fibre products and test methods

Practical benefits include consistent test execution, comparable results across facilities, clear acceptance criteria, and better traceability of fibre performance metrics such as attenuation, mode-field diameter, chromatic dispersion, macrobending loss and environmental durability.
