General Information
Overview
EN 4869-103:2024 - "Aerospace series - Expanded beam termini, fibre optic non‑physical contact in EN 3645 standard cavities - Part 103: Multimode male termini size 12" specifies the dimensional and performance requirements for a multimode, size 12 expanded beam male terminus designed for non‑physical contact fibre‑optic connections in EN 3645 standard cavities (connectors with EN 3155‑008M12 pin crimp contact cavities). The document is intended for aerospace connector assemblies and defines optical interface geometry, mechanical dimensions and qualification/test interfaces.
Key Topics and Requirements
- Contact designation: Identity letters for AR coating and fibre types (50 µm/125 µm and 62,5 µm/125 µm) and wavelengths (850 nm, 1 300 nm).
- Optical interface parameters:
- Beam size (1/e) for 62,5 µm fibre: 0.430 mm at 0.56 mm and 1 mm; 0.700 mm at 10 mm; 3.030 mm at 50 mm; 5.550 mm at 100 mm (850 nm values shown).
- Beam size for 50 µm fibre: 0.320 mm at 0.56 mm and 1 mm; 0.570 mm at 10 mm; 2.350 mm at 50 mm; 4.130 mm at 100 mm (850 nm values shown).
- Air gap between mating lenses: 0.61 ± 0.05 mm.
- Beam circularity: > 93 %; beam divergence specified (e.g., 0.00 ± 0.1° between 0.56 mm and 1 mm; 0.85 ± 0.1° between 1 mm and 10 mm).
- AR coating: Transmittance T > 98 % at specified wavelength; coating must be free from stains.
- Mechanical dimensions: Detailed size 12 contact geometry and tolerances (figures referenced).
- Qualification & testing: Component qualification as part of a complete connector assembly per EN 4869‑001; tests per the EN 2591 series (endurance at temperature, damp heat, salt mist, rapid temperature change, immersion at low air pressure, optical insertion loss/return loss and cleaning capability).
Applications and Users
- Primary users: aerospace connector manufacturers, avionic systems engineers, cable assembly houses, test laboratories, and procurement/specification engineers in civil and military aerospace.
- Typical applications: avionics backplanes, airborne sensors, flight‑critical data links, space vehicle harnesses and any harsh‑environment systems requiring reliable expanded beam termini and non‑physical contact multimode optical connections.
