Overview
EN 2591-6405:2001 is a CEN/AECMA aerospace test method standard that defines how to assess the ability of mated optical connection elements (including permanent connections) and fibre optic couplers to withstand axial load without mechanical or optical damage. It is part of the Aerospace series of connection element test methods and is intended to be used together with EN 2591-100 (general test requirements).
This standard applies to optical connectors and couplers used in aerospace electrical and optical systems and focuses on preserving optical performance (insertion loss, attenuation stability) while subjecting the mated pair to axial forces.
Key topics and technical requirements
- Scope: Evaluates axial load resistance of mated optical elements and fibre optic couplers to detect mechanical or optical degradation.
- Specimen preparation: Specimens must be fitted with normal accessories, mounted and terminated per the applicable product standard. Unless otherwise specified, product specifications should define:
- Maximum insertion loss
- Maximum permissible variation of attenuation
- Type and length of cable/fibre
- Test apparatus and setup: Uses the equipment and procedures referenced in related EN 2591 parts (see Related Standards). Test fixtures and measurement systems should be appropriate for monitoring optical performance under axial loading.
- Test procedure essentials:
- Follow EN 2591-405 axial load methods with optical-specific additions.
- Continuously monitor variation of attenuation (EN 2591-602) throughout the axial-load test.
- If required by the product standard, monitor electrical continuity of housings per EN 2591-205 during the test.
- Final measurements and pass/fail criteria: Verify optical performance after testing in accordance with relevant optical test methods such as EN 2591-601 (insertion loss), EN 2591-602 (attenuation variation) and mechanical mating/unmating criteria (EN 2591-408), as applicable.
Applications and who uses it
- Aerospace manufacturers and suppliers qualifying optical connectors and fibre optic couplers for aircraft and spacecraft.
- Test laboratories performing acceptance, qualification and periodic verification tests on mated optical connections.
- Design and reliability engineers assessing connector robustness to axial forces (e.g., cable tension, vibration-induced loads).
- Quality assurance and procurement teams requiring standardized axial-load test evidence for supplier approval and compliance.
