What is PD IEC/TR 62691- Guidelines for installation of optical fibre cables about?
PD IEC/TR 62691 is a technical report on optical fibre cables that discusses guidelines for installation of optical fibre cables to ensure safety and minimize hazards.
PD IEC/TR 62691 outlines recommendations for handling and installing optical fibre cables on metropolitan communication networks.
Installation methods covered under PD IEC/TR 62691 include underground ducts, trenchless technique, blowing in micro ducts, aerial installation on poles, lashed aerial in metropolitan networks, direct buried and 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 are commented and detailed under PD IEC/TR 62691.
PD IEC/TR 62691 includes extensive coverage on recommendations to ensure the safety of personnel and equipment when installing or maintaining these types of optical fibre cables on overhead power lines.
Note: Installation and maintenance of optical fibre cables on overhead power lines including the following are not covered by PD IEC/TR 62691:
- 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
Who is PD IEC/TR 62691- Guidelines for installation of optical fibre cables for?
PD IEC/TR 62691 on guidelines to the installation of optical fibre cables is useful for:
- Installation and maintenance staff for installation of optical fibre cables
Why should you use PD IEC/TR 62691- Guidelines for installation of optical fibre cables?
Optical fibre cabling provides a high-performance communications pathway whose characteristics can be degraded by inadequate installation.
PD IEC/TR 62691 guideline assists you with installation planning on route considerations, cable installation – tension considerations, duct installations – cable tension predictions, maximum tension/compression force exerted on cable, installation temperature, information, and training for the installation of optical fibre cables.
PD IEC/TR 62691 also guides on cable installation methods such as safety in confined spaces, FTTX installation, pre-installation procedures, installation of optical cables in underground ducts, installation of aerial optical cables, installation of the buried cable, installation in special situations, installation of indoor cables, blown systems, and cable location for installation of optical fibre cables. In addition, provides lightning protection for the installation of optical fibre cables.
With compliance and obedience to PD IEC/TR 62691, you can accurately install optical fibre cables to ensure the safety of the cable and minimise the associated hazards.
