The attenuation fo the luminous signal is measured in dB:
- the attenuation of the plastic fiber cable LiteWIRE, if placed correctly, is 1dB for 10m
- a tensioning bolt has an attenuation of 0.1 dB (max 0.2dB) and must be placed 1 every 10m of plastic fiber cable.
The LiteFENCE analyser can manage an attenuatio up to 31 dB. For this reason, 250m of fiber (with max. attenuation of 25dB) are normally used with 25 tensioning bolts (attenuation from 2.5 dB to 5 dB max.)
The devices which can detect the variation of light, like LiteFENCE and LiteCOPPER (and LiteSUN Plus, on request) , have a built-in fuction which measure the loss of optical power: the power meter. This allows to keep the attenuation monitored during the installation and to detect any possible mistakes during installation
