Scope
"Products This Standard covers optical fiber communications cable intended for outdoor use and normally installed aerially@ directly buried@ or placed in underground ducts. Additional requirements for ""figure-8"" aerial self-supporting cables are included inAnnex D@ as appropriate.Materials@ constructions@ and performance requirements are included in the Standard@ together with applicable test procedures. Refer to other published ICEA (ANSI/TIA) code product standards for information on fiber optic cable requirements for other applications: ? S-83-596: Optical fiber premises distribution cable (ANSI/TIA-472C000-B) ? S-101-696: Indoor-outdoor optical fiber drop cable (ANSI/TIA-472E000) ? S-110-717: Optical fiber drop cable (ANSI/TIA-472F000) Applications Space Products covered by this Standard are intended only for operation 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. Products 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 should be considered when determining appropriate requirements. Temperature Ranges The normal temperature ranges for cables covered by this Standard are given in Table 1-1 For the purpose of this standard@ very-low temperature applications@ are defined as -50 ??(-58 ?? per 1.4.1.6@ and are addressed in Annex C (Normative)@ which contains requirements for lower operating and storage temperatures than listed in Table 1.1. 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 use. For applications where a lower tensile rating is approprite the standard lower tensile rating is 1330 N (300 lbf). In all cases@ the residual load is defined as any load less than or equal to 30 percent of the installation tensile rating. For self-supporting aerial applications there are additional considerations that need to be addressed to ensure that the cable design is appropriate for the self-supporting distance and environmental loading conditions. See 7.30 and Annex D for information on figure-8 self-supporting aerial cable requirements and considerations. For aerial applications in which the optical cable is lashed to a separate messenger wire@ the use of a cable designed for a standard tensile rating for installation by direct burial@ trenching@ or pulling into duct may be adequate. Minimum Bend Diameter The standard minimum bend diameters for cables covered by this Standard are: Residual (Installed): 20 x Cable O.D. Loaded Condition (During Installation): 40 x Cable O.D. For very small cables@ such as those installed in miniature ducts@ manufacturers may specify a fixed cable minimum bend diameter (e.g.@ 300 mm) that is independent of the cable outer diameter (OD). For cables not having a circular cross-section@ bend diameter requirements are to be determined using the thickness (minor axis) as the cable and bending in the direction of the preferential bend.
