This part of IEC 60794, which is a generic specification, covers optical fibre ribbons. Requirements which are described in this part apply to optical fibre ribbon cables for use with telecommunication equipment and devices employing similar techniques, in particular optical fibre cables in IEC 60794-2 for indoor use, in IEC 60794-3 for outdoor use, IEC 60794-4 for self-supporting overhead use, IEC60794-5 for air blown use and IEC60794-6 for indoor/outdoor use. Detailed specification can be verified in documents of specification for each application such as IEC 60794-2 and IEC 60794-3.
