BS PD IEC/TR 62691 – Optical fibre cables. Guidelines to the installation of optical fibre cables

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.
