Description

IEC 60793-1-46 Ed. 1.0 b – Optical fibres – Part 1-46: Measurement methods and test procedures – Monitoring of changes in optical transmittance

Gives two methods for monitoring the changes in optical transmittance of optical fibres and cables that occur during mechanical and environmental testing. It provides a monitor in the change of optical transmission characteristics arising from optical discontinuity, physical defects and modifications of the attenuation slope. The methods are the change in transmittance by transmitted power, and by backscattering. They apply to both multimode and single-mode fibres.
