ITU-T L.77-2008在下水道管道中安装光缆.研究小组6

The installation of optical cables inside sewer ducts is basically a trenchless technique.Optical cable installation in sewer ducts presents many advantages compared with traditional trenchinstallation techniques, such as: less time for cable laying, not limited by weather conditions,increased protection of cable against damage, no traffic disruption, no noise pollution, noexcavation, no damage to road surfaces and underground installations, no heavy equipment, noinconvenience to businesses or to citizens.In general, there are two categories of sewers: man-accessible and non-man-accessible sewers.The definition of whether a sewer is man-accessible or not depends not only on national regulations,but also on the individual regulations of different sewer network operators.Usually, non-man-accessible sewers have diameters between 200 mm and 700 mm.Installation in non-man-accessible sewers is carried out with the help of robots. In man-accessiblesewers, both robot-assisted and manual installation of cables is feasible.Basically, there are three different methods to install optical cables into sewer ducts:a) Special armoured optical cables, designed to be directly installed at the bottom of thesewers;b) Self-supporting optical cables, designed to be directly suspended at the top part of sewers;c) Traditional optical cables or micro-cables, designed to be installed in protective ductswhich have to be installed before the cable installation.NOTE 1 – The most important optical cable structures and related performances suitable for these kinds ofinstallation techniques are described in [ITU-T L.78].NOTE 2 – The sewer optical cables and/or related infrastructure should be designed and manufactured for anexpected operating lifetime of at least 15 years. It should be possible to install or remove the cable to/fromthe sewer throughout the operation lifetime. The materials in the sewer optical cable and/or the relatedinfrastructure shall not present a health hazard within its intended use.

ASTM F2303-2003适合于铺设光缆和导管的重力下水道选择的标准实施规范

This practice is intended to assist engineers and sewer owner/operators in determining the suitability of sewers for a secondary use as hosts for optical fiber cables and conduits. It must be kept in mind that the primary use of the sewers is to carry wastewater and/or storm water. Any secondary use of the system shall not significantly impair the primary use. It is up to the engineer to decide upon any exceptions that may be involved in the selection process. Before the selection procedure begins, the installer must have explicit authorization from the owner/operator allowing an evaluation to be conducted for the installation of optical fiber cables or conduits within their sewer system. Engineers and owners should also be cognizant of how the installation of optical fiber cable or conduits will impact the future operational, maintenance and rehabilitation needs of the sewers.1.1 This practice specifically addresses the criteria for determining the suitability of gravity sewers for secondary uses such as the installation of optical fiber systems.1.1.1 This practice applies to the process of selecting gravity sewers that are appropriate for accepting an optical fiber system as opposed to standards for the installation, operation and maintenance of such system within sewers.1.2 This practice applies to both man accessible and man inaccessible sewer systems.1.3 The values stated in inch-pound units are to be regarded as the standard. The values provided in parentheses are for information purposes only.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
