This document provides information about fungal growth on the outer sheath of optical fibre cables and on the inner components of the cable. It also provides guidance for specifying the fungus resistance performance of optical cable outer sheath and internal cable components, fungus resistance testing, and evaluation after testing. This document applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to hybrid telecommunication cables having a combination of both optical fibres and electrical conductors. Since fungal growth requires high relative humidity and a warm atmosphere, the document is applicable to optical cables intended for transportation, storage and use under such conditions over certain period, for instance, five to seven days
