Overview

EN 2591-617:2002 (CEN/AECMA) defines a standardized method to check the ability of optical connection elements - including permanent connections and fibre optic couplers - to withstand temperature cycling. Intended for aerospace electrical and optical connection components, this part must be used together with EN 2591-100 (general test provisions).

This procedure focuses on verifying thermal resilience and monitoring variation of attenuation during controlled environmental cycles, supporting quality assurance for aerospace connectors and couplers.

Key Topics

• Scope: Temperature-cycling assessment for optical elements and fibre optic couplers; used in conjunction with EN 2591-100.
• Specimen preparation: Fit specimens with normal accessories, terminate per product standard; fit filler plugs for cavities with unterminated contacts (where applicable). Required specification details include:
  • type and length of cable/fibre
  • maximum permitted variation of attenuation
  • high and low temperature limits
  • durations at extreme temperatures and temperature change rates
  • number of cycles
• Apparatus:
  • Light Launch System (LLS) and Light Detector System (LDS) as defined in EN 2591-100
  • Climatic chamber capable of temperature control to ±3 °C
• Test method highlights:
  • Continuous measurement of attenuation variation (refer EN 2591-602, method A)
  • One basic cycle comprises: ramp to TA, dwell at TA, ramp to TB, dwell at TB, return to ambient, dwell at ambient
  • Default rate of temperature variation: 5 °C/min (unless product specification states otherwise)
  • Default dwell times: 30 minutes at TA, TB and ambient (unless otherwise stated)
• Post-test examination: Visual inspection according to EN 2591-6101

Applications

EN 2591-617:2002 is applicable for manufacturers, test laboratories and quality engineers working with:

• Aerospace optical connectors, plug-in and permanent optical connections
• Fibre optic couplers and assemblies used in aircraft and space systems
• Qualification and acceptance testing where thermal cycling could affect optical performance

Benefits of applying this standard include improved confidence in connector thermal reliability, detection of thermally induced attenuation shifts, and alignment with aerospace testing practices.

Related Standards

• EN 2591-100 - General test methods for elements of electrical and optical connection
• EN 2591-602 - Optical elements - Variation of attenuation and optical discontinuity (measurement method A)
• EN 2591-6101 - Optical elements - Visual examination

Using EN 2591-617 together with these referenced parts ensures a consistent, repeatable approach to temperature-cycling evaluation of aerospace optical elements and supports traceable test reporting and product specification compliance.
