Overview
EN 4626-003:2008 is a CEN (ASD-STAN) aerospace standard that defines the female adaptor for optical terminus in plug used with rectangular, multicontact, rack-and-panel connectors (Quadrax cavity) featuring a 2.5 mm diameter ferrule. The series targets aerospace optical connectors with flush contacts and an operating-temperature range of -65 °C to 125 °C (cable dependent). The document specifies form, fit and material options for adaptors used in high-reliability avionics and defence installations.
Key topics and requirements
- Scope: Characteristics and designation of the female adaptor for optical terminus in plug.
- Connector family: Rectangular multicontact rack-and-panel connectors, Quadrax cavity, 2.5 mm ferrule.
- Operating temperature: −65 °C to 125 °C (dependent on cable selection).
- Dimensions & mass: Detailed dimensional tolerances (mm) with a maximum mass of (6.1 ± 0.3) g; drawings referenced in the standard (see Figure 1).
- Materials
- Body: Metallic or composite material compatible with the product standard.
- Alignment sleeve (Table 1):
- Code 01: Zirconia ceramic or similar - recommended for single-mode and silica multimode fibres (50/125, 62.5/125, 100/140 µm).
- Code 02: Phosphor bronze or similar - recommended for multimode fibres.
- Optical, mechanical and climatic characteristics: Defined by cross-reference to EN 4626-101 (optical contact sub-assembly product standard).
- Designation: Standardized labelling convention (EN4626-003-) for component identification.
Applications and users
EN 4626-003:2008 is intended for:
- Aerospace OEMs and systems integrators specifying aerospace optical connectors for avionics racks and panels.
- Connector manufacturers and subcontractors designing and producing Quadrax optical adaptors and plug interfaces.
- Cable assembly suppliers selecting alignment sleeve materials for single-mode or multimode applications.
- Qualification and test laboratories performing conformity checks against material, dimensional and interface requirements.
- Defence and space system engineers requiring interoperable, temperature-rated optical terminations for harsh environments.
Typical applications include airborne data buses, sensor interfaces, avionics rack interconnects and other mission-critical optical links where reliable plug/adaptor interfaces are required.
