TIA TIA-472G000

Abstract

<strong>General Overview</strong> <br>This Standard covers optical fiber communications cables intended for installation in underground sewers, specifically storm and sanitary sewers. Materials, construction, and performance requirements are included in this Standard, together with applicable test procedures. Additional applicationsbased considerations are discussed as well. <br>Refer to ICEA S-87-640 for optical fiber communications cables intended for general outside plant use, ICEA S-110-717 for optical fiber cables intended for aerial, duct, and buried outdoor and indoor/outdoor drop applications, and ICEA S-104-696 for optical fiber communications cables intended for indoor/outdoor use. <br><strong>Applications Space</strong> <br>Products covered by this Standard are intended for use in metropolitan, urban, and suburban communications networks via use of underground infrastructures, in the last portion of all-optical networks, such as storm and sanitary sewers. These products convey communications signals (voice, video, and data) in metropolitan network rings and serve as point-to-point connections to the subscriber's premises via sewer laterals, in the last portion of the optical network. <br>These products are intended for use in sewer lines, using man-entry and nonman entry techniques. Such installations are intended to have no adverse effect on the efficiency of the sewer system. These cables are generally placed manually in pre-installed trays or conduits or may be secured to the sewer pipe wall by means of hooks, adhesive beds, sewer pipe liners, or may be tensioned intermittently, in order to maintain the cable and/or conduit out of the flow of the effluent. <br>The successful application of optical fiber cables in sewer systems requires that all identified maintenance to or rehabilitation of the sewer pipes be conducted prior to cable installation, in accordance with procedures under development by ASTM¹ <br>¹ Systems-level work on sewer-based communications applications is the prerogative of ASTM Technical Committee F36 on Technology and Underground Utilities.
