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

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Joakim Åström; Sofia Lindahl; [2021]
    Nyckelord :Cable; fibre optic cables; data transfer; data loss; functional criterium; damage criteria; bend diameter; temperature; fire conditions; heat flux; cone calorimeter; probabilistic distribution; risk analysis; Technology and Engineering;

    Sammanfattning : 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.
