38、eral Overview 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 ap

39、plications-based considerations are discussed as well. Refer to other ICEA optical cable product Standards which may have relevance to cables of this Standard: ICEA S-87-640 for optical fiber communications cables intended for general outside plant use ICEA S-104-696 for optical fiber communications

40、 cables intended for indoor/outdoor use. ICEA S-110-717 for optical fiber cables intended for aerial, duct, and buried outdoor and indoor/outdoor drop applications ICEA S-115-730 for optical fiber cables intended for Multiple Dwelling Unit (MDU) applications Note that the MDU application space may o

41、verlap that of drop cables. Refer to the following published ICEA optical cable product Standard for other applications ICEA S-83-596 for optical fiber cables intended for indoor applications. 1.1.2 Applications Space Products covered by this Standard are intended for use in metropolitan, urban, and

42、 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

43、 subscribers premises via sewer laterals, in the last portion of the optical network. When a hybrid cable (a cable with both optical fibers and metallic conductors) is required, the applicable metallic conductor requirements shall be as established ANSI/ICEA S-112-718-2013 2by agreement between the

44、end user and the cable manufacturer. The requirements of ICEA S-84-608, the filled OSP copper cable standard, should be considered when determining appropriate requirements. These products are intended for use in sewer lines, using man-entry and non-man entry techniques. Such installations are inten

45、ded 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 th

46、e cable and/or conduit out of the flow of the effluent. It is the intent that for many of the requirements of this Standard, the conduit or tray may provide the additional protection required of the cable system. The successful application of optical fiber cables in sewer systems requires that all i

47、dentified maintenance to or rehabilitation of the sewer pipes be conducted prior to cable installation, in accordance with procedures under development by ASTM1. 1.1.3 Temperature Ranges The normal temperature ranges for cables covered by this Standard are given in Table 1-1 Table 1-1 Cable Normal T

48、emperature Rangesa C F Operation -20 to +70 -4 to +158 Storage and Shipping -40 to +70 -40 to +158 Installation -20 to +60 -4 to +140 Note: a) See section 1.4.1.7 for information on sewer-only cables. 1.1.4 Tensile Rating For the purposes of this document, the standard tensile rating represents the

49、maximum allowable installation load for the cable. The standard tensile ratings for products covered by this Standard are as follows: 1335 N (300 lbf) for cables designed for installation by pulling into ducts. 440 N (100 lbf) for cables designed for installation into ducts with the assistance of compressed gases or for installation under low tension using 1 Systems-level work on sewer-based communications applications is the prerogative of ASTM Technical Committee F36 on Technology and Underground Utilities.
