Overview

EN 2591-602:2001 is a CEN/AECMA aerospace test methods standard for optical elements used in aircraft and spacecraft. It defines procedures to detect and record variation of attenuation and optical discontinuity of transmitted signals during environmental and mechanical testing of optical connection elements (including permanent connections) and fibre optic couplers. This part is intended to be used together with EN 2591-100 (general test preparation and equipment).

Key topics and technical requirements

  • Scope: Detection of attenuation changes and short-term optical interruptions that can affect link performance during environmental or mechanical stress.
  • Specimen preparation:
    • Fibre end preparation and cleaning must comply with EN 2591-100.
    • Fibres must be fixed to the measuring systems and movement minimized; minimum bend radius must not be exceeded.
    • Specimens are assembled with normal accessories and terminated with a short length of cable; a 4 m reference cable is used when required.
  • Test equipment:
    • A Light Launch System (LLS) and a Light Detector System (LDS) as defined in EN 2591-100 are mandatory.
  • Test methods:
    • Method A - Variation of attenuation: establish a zero-reference attenuation then monitor continuously during the test to record magnitude and frequency of attenuation changes. Sampling rate and maximum permissible variation are specified in the product/technical specification.
    • Method B - Optical discontinuity: set detection thresholds (dB drop and duration). Detect, trace and eliminate extraneous discontinuities; uneliminable discontinuities must be accounted for in performance assessment.
  • Data handling and acceptance:
    • Record discontinuities and attenuation variations as specified by the product standard.
    • Discount signals attributable to measurement equipment malfunction.
    • The number and severity of events must not exceed product-standard limits.

Practical applications and users

  • Who uses it:
    • Aerospace manufacturers, avionics and optical interconnect designers, test laboratories, quality assurance teams, and suppliers of fibre optic connectors and couplers.
  • Why it matters:
    • Ensures optical links maintain required performance under vibration, thermal cycling, shock and other environmental stresses common in aerospace.
    • Helps qualify components for installation in critical systems (flight controls, sensors, data buses) where signal integrity is vital.
