Full title and description

IEC TR 62691:2016 — Optical fibre cables — Guidelines to the installation of optical fibre cables. This Technical Report provides recommendations and practical guidance for handling and installing optical fibre cables in metropolitan communication networks, covering methods such as underground ducts, trenchless techniques, blowing in microducts, aerial installation, lashed aerial, direct burial and the use of trenches, as well as special situations (tunnels, bridges, sewers, gas and water pipes).

Abstract

IEC TR 62691:2016 (Edition 2.0) is a technical guidance document intended to assist designers, installers and maintenance teams with best practices for the installation of optical fibre cables in metropolitan networks. It consolidates installation recommendations, expands on special-environment installations transferred from related IEC clauses, and cross-references safety and installation advice for overhead power-line applications to IEC TR 62263.

Scope

This Technical Report gives recommendations for handling and installing optical fibre cables specifically for metropolitan communication networks. Covered installation methods include: underground ducts, trenchless techniques (e.g., HDD), blowing in microducts, aerial installation on poles, lashed aerial installations, direct burial and trenching. The report also comments on special installation situations such as tunnelling, lead-ins, on‑bridges, underwater, sanitary sewers, high‑pressure gas pipes and drinking water pipes. Installations and maintenance of optical cables on overhead power lines (OPGW, OPPC, OPAC, ADSS) are excluded and referred to IEC TR 62263.

Key topics and requirements

• Recommended installation practices for metropolitan network environments (duct routing, microduct blowing, lashed aerial techniques).
• Handling, pulling and blowing forces limits and guidance to protect fibre integrity during installation.
• Site‑specific guidance for special environments: tunnels, bridges, underwater crossings, sanitary sewers, high‑pressure gas and potable water conduits.
• Selection and preparation of cable routes, jointing/closure considerations and protection measures for buried and aerial cables.
• Safety and coordination notes, including a cross‑reference to IEC TR 62263 for power‑line related fibre installations.
• References to related test and construction standards (not normative requirements but practical guidance and references).

Typical use and users

This Technical Report is used by network planners, civil contractors, fibre installers, utilities, telecommunications operators, project managers and standards committees. It is intended for those responsible for planning and executing fibre installation works in urban and metropolitan areas who require consolidated installation guidance and practical considerations for varied site conditions.

Related standards

Commonly used in conjunction with IEC 60794 series (optical fibre test and specification standards), IEC 60794‑3‑10 / ‑3‑40 / ‑3‑50 / ‑3‑60 (application‑specific cable sections), IEC TR 62263 (installation on overhead power lines), IEC TR 62222 and various ITU‑T L‑series recommendations. National adoptions and implementation guides (BSI, NEN, ANSI/DS) often reference this TR for installation guidance.

FAQ

Q: What is this standard?

A: IEC TR 62691:2016 is a Technical Report providing guidelines and recommendations for the handling and installation of optical fibre cables in metropolitan communication networks.

Q: What does it cover?

A: It covers practical installation methods (underground ducts, trenchless techniques, microduct blowing, aerial and lashed aerial installations, direct burial and trenching) and discusses special installation situations such as tunnels, bridges, sewer use, and installations in gas and water pipes; it excludes overhead power‑line cable installations (see IEC TR 62263).

Q: Who typically uses it?

A: Network designers, installation contractors, telecom operators, utility engineers and maintenance teams use this TR as a practical reference for planning and executing fibre installations in urban/metropolitan contexts.

Q: Is it current or superseded?

A: IEC TR 62691:2016 (Edition 2.0) supersedes the 2011 edition; the 2011 edition was withdrawn when the 2016 edition was published. The 2016 edition is the active edition and was published on 24 June 2016.

Q: Is it part of a series?

A: Yes — it is part of the body of IEC documents covering optical fibre cables, closely associated with the IEC 60794 series and other TRs addressing installation and safety (for example IEC TR 62263). It is a guidance document (Technical Report) rather than a prescriptive product standard.

Q: What are the key keywords?

A: Optical fibre, fibre cable installation, metropolitan networks, blowing, microducts, aerial installation, direct burial, trenchless, IEC TR 62691.
