BS EN 3745-510 specifies a method of determining the attenuation variation of an optical cable during mechanical bending under load at the maximum operating temperatures.
BS EN 3745-510 also outlines preparation of specimen, apparatus and method to conduct bending test on fibres and cables to assess attenuation variation.
BS EN 3745-510 on attenuation variation is useful for:
The attenuation of an optical fibre measures the amount of light lost between input and output. Attenuation is the reduction in the power of the light signal as it is transmitted and is caused by passive media components such as cables, cable splices, and connectors.
Attenuation in optical fibre occurs due to many factors, including light absorption, cable bending, connector loss. BS EN 3745-510 helps you in measuring attenuation variation during such cases.
BS EN 3745-510 gives you guidelines on the attenuation variation of an optical cable to improve the functioning of optic fibres and cables.
