Overview

EN 3745-507:2002 - "Aerospace series - Fibres and cables, optical, aircraft use - Test methods - Part 507: Cut-through" is a CEN/AECMA European standard that specifies a standardized method for measuring the resistance of optical cables to penetration by a cutting surface for aerospace and aircraft applications. The procedure evaluates mechanical damage (cut-through) while monitoring optical performance (attenuation) to confirm whether an optical cable maintains integrity under localized cutting forces.

Key Topics and Requirements

  • Scope: Test method for cut-through resistance of optical cables used in aircraft and aerospace systems.
  • Specimen preparation: Specimens are prepared per the relevant product standard and stabilized under standard test conditions for 24 hours as defined in EN 3745-100.
  • Specified specimen details (unless otherwise stated):
    • Cable length: 2 ± 0.05 m
    • Load F: 20 N
    • Rate of load application: 50 ± 10 N/min
    • Duration of load application: 1 min
  • Apparatus required:
    • Light Launch System (LLS) and Light Detection System (LDS) as defined in EN 2591-100
    • Needle and support (needle support pressing onto fixed plate)
    • Climatic chamber for environment control
    • Test rig to apply specified load through the movable needle support
  • Test sequence:
    • Visual examination of the jacket (pre-test)
    • Mount specimen, connect to LLS/LDS and zero attenuation
    • Apply the prescribed load and rate, monitor attenuation continuously (EN 3745-301, method C)
  • Post-test evaluation: Assess breakage or non-breakage per EN 3745-201 and record attenuation change.

Applications

  • Qualification and acceptance testing of aerospace optical fibres and cables to ensure mechanical robustness against cutting/penetration hazards in aircraft installations.
  • Used by cable manufacturers, aerospace suppliers, test laboratories, certification bodies, and design engineers to:
    • Verify mechanical protection and jacket performance.
    • Confirm that optical performance (attenuation) remains within acceptable limits after a cut-through event.
    • Support product specifications and compliance evidence for aircraft system design and maintenance.

Related Standards

  • EN 2591-100 - elements of electrical and optical connection: LLS/LDS definitions
  • EN 3745-100 - general test conditions for optical fibres and cables
  • EN 3745-201 - visual examination and breakage evaluation
  • EN 3745-301 - attenuation measurement methods (method C referenced)

This standard is essential for ensuring optical cable safety and reliability in aerospace environments where localized cutting forces may occur. Keywords: EN 3745-507:2002, cut-through, optical cable test, aerospace optical fibres, aircraft cable testing, attenuation monitoring, LLS, LDS.
