European foreword
This document (prEN 4641-103:2023) has been prepared by the Aerospace and Defence Industries
Association of Europe — Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 4641-103:2010.
The main changes with respect to the previous edition are as follows:
— EN 4641-103 (P1), 11/2010 — Editorial improvements and update of the scope to change “single
mode fibre core” to “simplex fibre”.

1 Scope
This document specifies the general characteristics, conditions for qualification, acceptance and quality
assurance for a fibre optic cable with a 62,5 µm/125 µm simplex fibre, 2,74 mm outside cable diameter
and of semi-loose construction. The basic construction is the cable defined in EN 4641-102 with added
sheaths for ruggedized usages.
