42、 Scope 1.1.1 ProductsThis Standard covers optical fiber communications cable intended for outdoor use and normally installed aerially, directly buried, or placed in underground ducts. Additional requirements are included in Annex D for “figure-8” aerial self-supporting cables and in Annex F for all-
43、dielectric self-support cables, as appropriate. Materials, constructions, and performance requirements are included in the Standard, together with applicable test procedures. Refer to other published ICEA (TIA) cable product standards for information on optical fiber cable requirements for other app
44、lications: g120 S-83-596: Standard for indoor optical fiber cable (TIA-472C000-C) g120 S-104-696: Indoor-outdoor optical fiber cable (ANSI/TIA-472E000) g120 S-110-717: Optical fiber drop cable (ANSI/TIA-472F000) g120 S-112-718: Optical fiber cable for placement in sewer environments (TIA-472G000) 1.
45、1.2 Applications SpaceProducts covered by this Standard are intended for operation only under conditions normally found in communications systems. These products normally convey communications signals (voice, video, and data) from point-to-point or point-to-multi-point, external to buildings. Produc
46、ts covered by this Standard may be factory terminated with connectors or splicing modules. When a composite cable is required, the applicable metallic conductor requirements shall be as established by agreement between the end user and the cable manufacturer. The requirements of ANSI/ICEA S-84-608 s
47、hould be considered when determining appropriate requirements. 1.1.3 Temperature RangesThe normal temperature ranges for cables covered by this Standard are given in Table 1.1 For the purposes of this standard, very-low temperature applications are defined as -50 g113C (-58 g113F) per 1.4.1.6 and ar
48、e addressed in Annex C (Normative), which contains requirements for lower operating and storage temperatures than listed in Table 1.1. ANSI/ICEA S-87-640-2011 2 Table 1.1 - Cable normal temperature ranges C (F) Operation -40 to +70 (-40 to +158) Storage and Shipping -40 to +70 (-40 to +158) Installa
49、tion -30 to +60 (-22 to +140) 1.1.4 Tensile Rating The standard installation tensile rating for cables covered by this Standard is 2670 N (600 lbf). Higher tensile ratings are also acceptable. For applications where a lower tensile rating is appropriate the standard lower tensile rating is 1330 N (300 lbf). In all cases, the residual load is defined as a load equal to 30 percent of the installation tensile rating. For self-supporting aerial applications there are additional considerations that need to be addressed to ens
