Aerospace series. Fibres and cables, optical, aircraft use. Test methods - Attenuation Ingestion-build-256245 a unit is necessary to1 Scope This European Standard 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
