Overview
EN 4701-001:2014 is a CEN aerospace standard that defines the technical specification for rectangular, modular optical connectors intended for aerospace on‑board use. It covers EN 4165 housings fitted with removable optical modules using EN 4531‑101 contacts, rated for an operating temperature of 125 °C. The standard sets out general characteristics, qualification and acceptance conditions, quality assurance requirements, and the required test programs and test groups.
Key topics and technical requirements
- Connector family: Derived from EN 4165 rectangular modular connectors; modules are single‑bloc and removable from the rear.
- Optical contacts: Use EN 4531‑101 hermaphroditic, spring‑loaded contacts with a 2.5 mm ferrule diameter. Precise alignment via a central alignment pin/socket and alignment sleeves.
- Materials and sealing: Module and contact materials follow the product standards (EN 4531, EN 4701‑002). Front‑face and rear‑face sealing, contact boots and retention clips are specified to ensure environmental protection.
- Mechanical design: Modules must resist cracking and allow individual contact installation without module removal. Extraction/install tools referenced (e.g., SAE M81969/14‑04). Connector mating sequences and anti‑mis‑mate features follow EN 4165 rules.
- Qualification, acceptance & quality assurance: Defines conditions for product qualification, batch acceptance and manufacturer quality control in line with aerospace requirements (EN 9133 referenced).
- Test programs: Implements EN 2591 series test methods tailored to these connectors. Representative tests and limits in the standard include:
- End‑face visual inspection (minimum 200× magnification)
- Mechanical endurance: 500 mating/unmating cycles (cleaning intervals specified)
- Environmental: salt mist (452 h with mating/unmating cycles), damp heat (10 cycles), sand/dust, vibration and shock (e.g., 100 g shock severity), air leakage (40 kPa, max 16 cm3/h/module)
- Specified mating/unmating and coupling torques for screw and push‑pull latches (values given for 2‑ and 4‑module housings)
Applications and users
- Primary users: aerospace OEMs, avionics integrators, component manufacturers, and qualification/test laboratories.
- Typical applications: fiber‑optic signal and data links in aircraft and aerospace on‑board systems where rugged, modular, sealed optical interconnects are required at elevated temperatures (up to 125 °C). Useful for design specification, procurement, supplier qualification and acceptance testing.
