Overview
EN IEC 60794-1-301:2023 (IEC 60794-1-301:2023) defines the bend test (Method G1) for optical cable elements. It is part of the IEC 60794 series for optical fibre cables and provides a generic, repeatable procedure to evaluate the mechanical property of bending by measuring attenuation changes when cable elements (fibres, ribbons, core tubes, breakout units, microduct units, etc.) are wound on a mandrel. The standard applies to optical fibre cables used with telecommunication equipment and to hybrid cables that include both optical fibres and electrical conductors. This edition partially replaces IEC 60794-1-23:2019 and adds reporting requirements and temperature specification guidance.
Key topics and requirements
- Purpose: Characterize cable elements for splicing/termination by determining attenuation increase caused by bending.
- Sample & conditioning: Samples must be long enough for testing and preconditioned for at least 4 hours at the test temperature.
- Apparatus: Uses a smooth-surfaced mandrel (diameter specified in the detail specification) and an attenuation measurement system compliant with IEC 60793-1-46 (monitoring changes in optical transmittance).
- Procedure: Wind the element on the mandrel at minimal tension. The number of turns and number of winding/unwinding cycles are to be specified in the relevant product/detail specification. Measure attenuation during and after the test.
- Acceptance criteria: Any increase in attenuation must meet limits defined in the relevant specification. Intrinsic fibre attenuation must be accounted for when evaluating bend-induced loss.
- Parameters to specify: optical test wavelength, mandrel diameter, number of turns, cycles, test temperature (can be different from room temperature and should reflect min/max installation or termination temperatures), and maximum allowed attenuation change.
- Reporting requirements: Report apparatus and measurement technique, detailed sample description, and attenuation variation during and after the test.
Practical applications and users
EN IEC 60794-1-301:2023 is essential for:
- Cable manufacturers - to validate design and ensure splice/termination performance under bending.
- Test laboratories and QA teams - for consistent, repeatable bend-loss testing and certification.
- Telecommunications equipment vendors and installers - to assess compatibility of cable elements with splice closures and routing constraints.
- Specification writers and procurement - to define acceptance limits and test conditions (wavelength, mandrel diameter, temperature) in purchase documents.
Keywords: EN IEC 60794-1-301:2023, bend test, method G1, optical fibre cables, cable elements test methods, mandrel bend, attenuation measurement, IEC 60793-1-46, optical cable testing.
