Overview
EN 3733-105:2008 is a European standard published by CEN that specifies the product characteristics of aerospace-grade optical circular connectors. This standard focuses on the dummy receptacle connector with two holes fixing designed for single channel fibre optic plug connectors. The connectors are intended for high-reliability applications in the aerospace industry, supporting continuous operation at temperatures up to 150 °C.
Key features of EN 3733-105 include precise connector interface dimensions, mechanical mounting requirements, and material specifications ensuring consistent performance under demanding environmental conditions. This standard complements the technical specifications outlined in EN 3733-001 and the product listings in EN 3733-002.
Key Topics
- Connector Type: Optical circular, single channel, coupled by self-locking ring for secure mating.
- Operating Conditions: Rated for continuous use at temperatures up to 150 °C, suitable for aerospace environments.
- Mechanical Specification: The dummy receptacle features a two holes fixing system for rear panel mounting, ensuring stable and reliable installation.
- Materials: Constructed with a nickel-copper shell for durability and a fluorosilicone seal for environmental protection.
- Dimensions: Strict adherence to millimeter-precise interface dimensions and panel cut-out requirements to assure interchangeability and compatibility.
- Keying System: Universal keying to accommodate any plug connector keyway orientation.
- Testing and Qualification: Connector durability and performance tested according to EN 2591-100 methods and qualified following EN 3733-004 standards.
- Marking and Designation: Clear marking protocols for identification per EN 3733-001, including product codes and class information to facilitate traceability.
Applications
EN 3733-105 standardized connectors are designed primarily for aerospace and defense industries, where fiber optic communication links demand:
- High-temperature resistance connectors operating reliably in harsh environments.
- Robust and secure optical interconnects for avionics and flight control systems.
- Precision-mounted receptacle connectors facilitating maintenance and modular design.
- Compatibility with other EN 3733-series connectors promoting interoperable system design.
- Situations requiring dummy receptacles for testing, protective capping, or unused connector ports.
These connectors ensure signal integrity and environmental sealing necessary for fiber optic transmission systems on aircraft, satellites, or ground support equipment exposed to temperature extremes and mechanical stress.
