Overview
EN 4641-001:2018 - Aerospace series - Cables, optical, 125 µm diameter cladding - Part 001: Technical specification - is a European standard that defines the general characteristics, qualification, acceptance, quality assurance and required test methods for fibre optic cables with a 125 µm cladding outside diameter used in aerospace applications. The document is intended for manufacturers, avionics engineers, quality and procurement teams involved with aerospace optical cable design, testing and supply.
Key topics and technical requirements
- Scope: Applies to fibre optic cables with a 125 µm silica cladding and single all‑silica core protected by a primary coating. Cable constructions covered include tight and semi‑loose structures with outer jacket, strength members and buffer layers.
- Materials & construction: Cable component materials, colours and dimensions are defined in associated product standards; examples include outer jacket, inner sheath, strength member and buffer.
- Optical fibre requirements: Single silica core/cladding, primary coating, dimensional and optical properties (attenuation, numerical aperture, bandwidth, chromatic dispersion) tested per referenced methods.
- Extensive test methods: Tests are specified (many via EN 3745-100 and related parts) including visual inspection, dimensions, attenuation (including temperature cycling), optical discontinuity, immunity to ambient light, thermal shock, cold bend, flammability, accelerated ageing, humidity resistance, abrasion, micro‑bending, tensile, impact, torsion, kink, bend, crush, smoke density, toxicity and radiation resistance.
- Qualification & sampling: Qualification specimens must be supplied on drums/spools/coils with labelling. Qualification tests apply at product introduction and certain tests are repeated periodically (qualification maintenance every 36 months).
- Quality assurance: Manufacturer responsibility - QA system per EN 9133, documentary evidence of inspections retained for five years and available to authorities.
- Marking & designation: Cable designation follows EN 4641 numbering and product codes. Marking must include cable reference, manufacturer and two‑digit year (ISO 2574). UV laser marking acceptable; hot stamping forbidden.
Applications and who uses this standard
- Primary users: Aerospace cable manufacturers, avionics systems integrators, aircraft OEMs, procurement and quality assurance teams, and certification/test laboratories.
- Practical uses: Specifying and qualifying in‑aircraft fibre optic cabling for data, sensors and communication links where aerospace environmental, mechanical and safety criteria (flammability, toxicity, radiation) apply.
