Overview

The standards of the EN 3745 series describe test methods for optical fibres and cables for aircraft use. Part 301 specifies procedures for the practical measurement of the attenuation and variation in attenuation of optical fibre or optical cable (both hereafter referred to as fibre). Methods A and B are intended for fibre acceptance testing and shall be performed on fibre lengths greater than 1 km. Method C is intended for attenuation measurement required during environmental and mechanical testing and shall be performed on fibre lengths less than 100 m. Method D is intended for testing of backscattering. With respect to the previous edition DIN EN 3745-301:2003-05, method D for testing of backscattering has been included. The standards of the EN 3745 series have been prepared by ASD-STAN, Technical Section Electrics, Avionics, with the participation of German experts of the Aerospace Standards Committee. The European Committee for Standardization (CEN) declared the Aerospace and Defence Industries Association of Europe (ASD-STAN) responsible for the preparation of European standards (EN) for the field of aerospace. The responsible German standardization committee is Working Committee NA 131-04-10 AA "LWL und LWL-Komponenten" ("LWL and LWL-components") of the Aerospace Standards Committee at DIN.
