Overview
EN 4641-105:2010 is a CEN aerospace product standard for a semi-loose, ruggedized quadraxial fibre optic cable. It defines the design, qualification, acceptance and quality assurance requirements for a 4‑core cable built from two semi-loose 62.5/125 µm Graded Index (GI) single cables, with a nominal outside diameter of 5.72 mm. The standard was prepared under ASD‑STAN and approved by CEN (November 2010).
Key topics and technical requirements
- Cable construction: Quadraxial assembly of two 1.8 mm semi‑loose component cables, fillers, PTFE barrier tape and an extruded fluoropolymer outer jacket.
- Fibre type and geometry: Four 62.5/125 µm GI fibres (nominal); numerical aperture 0.275 ± 0.015.
- Mechanical and environmental limits:
- Operating temperature: −65 °C to +150 °C
- Finished outside diameter: (5.72 ± 0.25) mm
- Minimum jacket wall thickness: ≥ 0.20 mm
- Minimum bend radius (installation/long term): 10 × OD (≈ 60 mm)
- Optical performance:
- Attenuation ≤ 4 dB/km at 850 nm and ≤ 2 dB/km at 1 300 nm (at 20 °C)
- Maximum permitted short‑term attenuation variations specified for many tests (e.g., ≤ 0.25 dB for temperature cycling, cold bend, abrasion)
- Materials: PTFE fillers/barrier tape and extruded fluoropolymer outer jacket specified for ruggedized use.
- Qualification and tests: Ruggedized cable tests per EN 3745‑100 including visual inspection, attenuation, temperature cycling, thermal shock, cold bend, flammability, abrasion, tensile, impact, torsion, crush, smoke density and toxicity limits.
- Marking, colour and storage:
- Marking per EN 2424 (manufacturer code and year) using marker tape under jacket or UV laser (no hot stamping).
- Typical jacket colour: light purple or customer specified.
- Storage: humidity < 90 %, −65 °C to 85 °C; tensile load < 30 N; allow warming before handling after subzero storage.
