BS EN 60793-1-46:2002

This standard BS EN 60793-1-46:2002 Optical fibres. Measurement methods and test procedures is classified in these ICS categories:

• 33.180.10 Fibres and cables

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.
