BS PD IEC/TR 62691:2016

BS PD IEC/TR 62691:2016, which is a Technical Report, gives recommendations for handling andinstalling optical fibre cables on metropolitan communication networks. Installation methodscovered by this document include underground ducts, trenchless technique, blowing inmicroducts, aerial installation on poles, lashed aerial in metropolitan networks, direct buriedand use of trenches.Special installation situations such as tunnelling and lead-in installations, on-bridges,underwater, use of sanitary sewers, high pressure gas pipes and drinking water pipes arecommented and detailed.Installation and maintenance of optical fibre cables on overhead power lines including thefollowing are not covered by this document and are referred to in IEC TR 62263:

• optical ground wire (OPGW) fibre cable;
• optical phase conductor (OPPC) fibre cable;
• optical attached fibre cable (OPAC);
• all dielectric self-supporting (ADSS) optical fibre cable.

IEC TR 62263 includes an extensive coverage on recommendations to ensure the safety ofpersonnel and equipment when installing or maintaining these types of optical fibre cables onoverhead power lines.Cross References:IEC 60794IEC 60794-3IEC 60794-3-10IEC 60794-3-40IEC 60794-3-50IEC 60794-3-60IEC 60794-1-21IEC 60794-5IEC TR 62362IEC TR 62470IEC TR 62263IEC TR 61328IEC TR 62901 ISO/IEC 24702ISO/IEC TR 29106ITU-T K.47ITU-T L.38ITU-T L.48ITU-T L.49ITU-T L.57ITU-T L.61ITU-T L.77IEC TR 62222
