Overview
EN 3733-101:2008 is a CEN/Aerospace series product standard that defines the characteristics of protective covers for single-channel fibre optic receptacle connectors (four- and two‑hole fixing) designed for continuous operation up to 150 °C. It describes the required dimensions, materials and designation rules for receptacle protective covers used on circular optical connectors coupled by a self‑locking ring. Interface dimensions, test tables and qualification requirements are defined in the companion Technical Specification EN 3733-001, while EN 3733-002 lists product types and codification.
Key topics and requirements
- Scope: Protective cover (receptacle) for single-channel optical circular connectors with 2‑ or 4‑hole fixing; operating temperature up to 150 °C continuous.
- Dimensions & mass: Drawn interface dimensions are specified in the standard (examples from the document: thread M11×1,0‑6g; overall envelope limits such as Ø14.5 mm and 18.6 mm maximum). Maximum mass: 17.9 g.
- Materials: Nickel‑copper alloy cover shell and rivet, nylon cord, fluorosilicone seal, cadmium‑plated copper eyelets.
- Designation & marking: Example designation format shown (e.g., COVER EN3733-101B). Marking and detailed identity blocks reference EN 3733-001. Part code I9005 may be included where required.
- Qualification: Covers are qualified when tested to the applicable qualification requirements in EN 3733-001. Test methods reference EN 2591-100 (general test methods for aerospace electrical/optical connections).
- Application compatibility: Intended for use with connector product standards EN 3733-004 and EN 3733-005; EN 3733-002 lists compatible combinations.
Applications and users
Practical uses and stakeholders:
- Aerospace & defence OEMs: Protect optical receptacles on aircraft, spacecraft and airborne systems during maintenance, transport and storage.
- Connector manufacturers: Design and produce protective covers that meet material, dimensional and qualification requirements.
- Design & systems engineers: Specify compliant receptacle covers for high‑temperature optical interconnects in avionics and aerospace subsystems.
- Procurement & quality assurance: Use the standard for product selection, inspection criteria and qualification acceptance.
- Test laboratories & certification bodies: Apply referenced test methods (EN 2591-100 and EN 3733-001) for qualification and verification.
