Applications and users
EN 3375-008:2024 is aimed at:
- Aerospace cable manufacturers and suppliers producing Star Quad 100 Ω wiring.
- Avionics and systems engineers specifying 100 Mbit/s Ethernet cabling for aircraft onboard networks.
- Procurement, quality assurance and certification teams verifying compliance with aerospace cable standards.
- Aircraft OEMs, MRO organisations and system integrators requiring robust data cables for harsh airborne environments.
Typical practical uses include in‑aircraft digital data links where stable impedance, low attenuation and controlled crosstalk are critical for reliable Ethernet performance under extreme temperature and vibration conditions.
