Overview
EN 4626-202:2009 is a CEN product standard in the Aerospace series that specifies the optical contact assembly for a 900 µm buffered fibre receptacle used in rectangular multicontact, rack-and-panel connectors with a Quadrax cavity and 2.5 mm ferrule. The standard defines the dimensions, performance requirements and basic assembly/cleaning guidance for this optical contact intended for use inside equipment boxes. It applies to flush-contact optical connections rated for operating temperatures −65 °C to 125 °C (cable dependent) and is part of the family of aerospace connector standards for high-reliability optical interconnects.
Key topics and technical requirements
- Scope and parts: Defines the EN 4531-101 fibre optical contact variant for 900 µm buffered fibre EN 4641 and the associated alignment boot.
- Dimensions and tolerances: Ferrule and overall optical contact dimensions, mass (~1.0 ± 0.3 g), and interface geometry for rack-and-panel mating.
- Mechanical interface: Spring force when mated - typical 9 N (min 5 N, max 13 N); maximum spring outer diameter 3.95 mm.
- Environmental and mechanical testing: Tests referenced to EN 2591-100, including:
- Visual inspection, dimensional checks
- Thermal endurance: 1 000 hours at 125 °C
- Rapid temperature change cycles (125 °C / −55 °C)
- Salt mist, damp heat cyclic, shock, and vibration (per ARINC 600 compatibility)
- Mechanical endurance: 500 mating cycles
- Optical performance limits:
- Insertion loss: ≤ 1 dB during and after tests
- Optical discontinuity threshold: no discontinuity > 0.5 µs
- Return loss: RL < −21 dB
- Assembly and maintenance: Cleaning procedure for unmated contacts (lint‑free tissue, suitable solvent, dry air) and use of ARINC 600 adaptor insertion/extraction tooling.
Applications and users
EN 4626-202:2009 is intended for:
- Aerospace and avionics manufacturers specifying rack-and-panel optical connectors and Quadrax cavities
- Connector designers and component suppliers creating 2.5 mm ferrule optical contacts for equipment boxes
- Systems integrators and test engineers ensuring compliance with environmental and optical performance (temperature, vibration, shock)
- Procurement and quality teams requiring harmonized product standards for aircraft and defense installations
Typical applications include high-reliability optical links in avionics racks, equipment enclosures, sensor interfaces and military aerospace systems where space-constrained, multicontact optical interconnects are required.
