Damage Criteria for Fibre Optic Cables Exposed to Fire - Using data transfer as functional criterium

Abstract
The aim of this master thesis was to analyse the possibility to use fibre optic cables for critical safety features in high reliability facilities. In more detail, this report investigates how transferred data in fibre optic cables are affected by fire and if there is any risk that the data becomes corrupted or lost when exposed to fire conditions. This report also investigates if this risk can be tied to a critical temperature or radiation. This was investigated by testing the fibre optic cables in a cone calorimeter, which exposed them to different heat fluxes. The results from the tests were analysed with regards to data loss, temperature, and functional criteria. A statistical data analysis was conducted as well. The analysis did not... (More)

This was investigated by testing the fibre optic cables in a cone calorimeter, which exposed them to different heat fluxes. The results from the tests were analysed with regards to data loss, temperature, and functional criteria. A statistical data analysis was conducted as well. The analysis did not show a strong correlation between data loss and temperature, it did however show a stronger correlation between temperature and bend diameter. A correctly installed cable is more vulnerable to elevated temperatures if the thermal influences from a fire causes the bend diameter to decrease. (Less)
