39、s optical fiber communications cables intended for use in outdoor andindoor/outdoor optical fiber drop applications. Materials, construction, and performancerequirements are included in this Standard, together with applicable test procedures.Refer to ICEA S-104-696 for optical fiber communications c
40、ables intended for use in othercombined indoor/outdoor applications, and to ICEA S-87-640 for optical fibercommunication cables intended for use in other outdoor applications. Refer to ICEAS-83-596 for optical fiber communications cables intended only for indoor use.1.1.2 Applications SpaceProducts
41、covered by this Standard are intended for operation under conditions normallyencountered in the last portion of all-optical networks. This space exists from the NetworkAccess Point (NAP), or other hardware serving that purpose, ending at or inside thesubscriber premises. These products convey commun
42、ications signals (voice, video, anddata) between the communications network and the subscriber premises. Productscovered by this Standard may be factory-terminated with connectors or othertelecommunications hardware as appropriate.For the purposes of this Standard, user premises are defined as resid
43、ential properties andsmall to medium sized businesses located in facilities that can be served by an opticalcable having 12 or fewer fibers, with typical distances less than or equal to 100 m (300 ft)in length. Most applications will only require cables with four or fewer fibers. Productscovered by
44、this Standard are not intended for use in extended distance applications, whichare typically characterized by higher fiber count cables and which specify more stringentdesign and performance requirements. The suitability of products covered by thisStandard in applications other than those for which
45、they are intended should be as agreedupon between the manufacturer and user.1.1.3 Temperature RangesThe normal temperature ranges for cables covered by this Standard are given inTable 1-1.ICEA S-110-717-2003ANSI/TIA-472F0002Table 1-1Cable Normal Temperature RangesOutdoor CableIndoor/Outdoor Cable(fi

47、ents the maximumallowable installation load for the cable. The standard tensile ratings for products coveredby this Standard are 1335 N (300 lbf) for cables designed for installation by pulling, and440 N (100 lbf) for cables that are direct-buried, placed in the ground by trenchingequipment, or blow
48、n into ducts. The residual load is defined as a load equivalent to 30 %of the standard tensile rating, as related to all cable designs except aerial self-supporting.For self-supporting aerial applications there may be additional considerations, based onthe particular application, which need to be ad
49、dressed to ensure that the cable design isappropriate for the self-supporting distance (typically 30 m 100 ft or less) andenvironmental loading requirements. See Paragraph 7.24 and Annex C for informationon aerial plant requirements and considerations.For aerial applications in which the drop cable is lashed to a separate messenger wire,the use of a cable designed for installation by direct burial, trenching, or pulling into ductmay be adequate.1.1.5 Minimum Bend DiameterThe standard minimum bend diameters for cables covered by this Standar
