25、se band unit (BBU) of a cell site to the remote radio unit (RRU) on the associated structure. These cables may be hybrid design, incorporating electrical conductors for low voltage power delivery and control, or standalone optical cables. This standard primarily references ANSI/ICEA S-87-640-2011 (I

26、CEA 640) and ANSI/ICEA S-104-696-2013 (ICEA 696) for optical performance requirements. Standalone optical cables covered by this standard are essentially ICEA 640 or ICEA 696 compliant cables, less requirements deemed not applicable to the application such as Hydrogen Evolution in Cable, Water Penet

27、ration Test and Mid-Span Buffer Tube Storage. As such, standalone optical cables complying with ICEA 640 or ICEA 696 shall be considered compliant with this standard. 1.1.2 Application Space All designs covered by this Standard are intended for operation under normal conditions found in the communic

28、ations users locations, most often cell towers. These products normally convey digital communications signals (voice, video, and data) from point to point or point to multi point. Products covered by this Standard may be factory terminated with connectors or splicing modules. 1.1.3 Temperature Range

29、s The normal temperature ranges for cables covered by this Standard are listed in Table 1-1: For the purposes of this standard, very-Iow temperature applications are defined as -50 C (-58 F) per 1.4.1.6 and are addressed in Annex C of ICEA 640 (Normative), which contains requirements for lower opera

30、ting and storage temperatures than listed in Table 1-1. Table 1-1 Temperature Ranges Cables with No Fire Resistance Rating Cables with Plenum Fire Resistance Rating Cables with Other Fire Resistance Rating C (F) C (F) C (F) Operation -40 to +70 (-40 to 158) -40 to +70 (-40 to 158) -40 to +70 (-40 to

31、 158) Storage and Shipping -40 to +70 (-40 to 158) -40 to +70 (-40 to 158) -40 to +70 (-40 to 158) Installation -30 to +60 (-22 to +140) -0 to +60 (+32 to +140) -10 to +60 (+14 to +140) 1.1.4 Tensile Rating Antenna locations vary widely, which places varying demands on the cables servicing them. App

32、ropriate tensile ratings for FTTA cables are thus application dependent. FTTA cables that are designated for vertical, self-support applications, e.g., free-hanging inside a monopole, shall be rated for residual load that matches or exceeds the weight of the free hanging portion of the cable. ANSI/I

33、CEA S-119-741-2016 2 1.1.5 Minimum Bend Diameter The standard minimum bend diameters for cables covered by this Standard are: Residual (Installed or static): 20 x Cable OD Loaded Condition (During Installation or self-support): 40 x Cable OD For cables not having a circular cross-section, bend diame

34、ter requirements are to be determined using the thickness (minor axis) as the cable diameter and bending in the direction of the preferential bend. Smaller cable bend diameters are permissible as agreed upon between the user and manufacturer. 1.1.6 Fire-Resistance Fire resistance is application depe

35、ndent. The user should consult the local Authority Having Jurisdiction (AHJ) to determine required fire resistance ratings, if any. Some fire resistance ratings that may be appropriate are: 1.1.6.1 Plenum Cables Cables listed as having adequate fire-resistance and low smoke producing characteristics

36、 for use in ducts, plenums and other space used for environmental air. Plenum rating is typically only applicable to communications cables and power-limited circuit cable. In the context of this standard, Plenum rating would only be applicable to standalone optical cables. 1.1.6.2 Riser Cables Cable

37、s listed as having fire-resistant characteristics capable of preventing the carrying of fire from floor to floor for use in a vertical run in a shaft or from floor to floor. Riser rating is typically only applicable to communications cables and power-limited circuit cable. In the context of this sta

38、ndard, Riser rating would only be applicable to standalone optical cables. 1.1.6.3 General Purpose Cables listed as being resistant to the spread of fire for general-purpose use, with the exception of risers, plenums, and other space used for environmental air. General Purpose rating is typically on

39、ly applicable to communications cables and power-limited circuit cable. In the context of this standard, General Purpose rating would only be applicable to standalone optical cables. 1.1.6.4 Tray Rated Cables listed as being intended for use in accordance with Article 336 and other applicable parts

40、of the National Electrical Code (NEC), ANSI/NFPA 70, in cable trays, in raceways, and where supported in outdoor locations by a messenger wire. 1.2 General ANSI/ICEA S-119-741-2016 3 This publication is arranged so that cables may be selected from numerous constructions covering a broad range of ins

41、tallation and service conditions. Parts 2 and 3 designate the materials, material characteristics, dimensions and tests applicable to the particular component. Part 4 covers assembly, cabling, and identification of the individual optical fibers. Part 5 includes cable coverings. Part 6 provides other

42、 pertinent requirements not otherwise addressed by Parts 1 through 5 or by Parts 7 and 8 of this Standard. Part 7 describes the test methods and performance requirements applicable to the component materials and completed cables manufactured under this Standard. If there is a conflict between Parts

43、1 through 6 and Part 7, the provisions of Part 7 apply. Part 8 contains routinely specified optical performance, test methods and requirements for finished cables. Part 9 contains cross-references to other standards and publications. Annex A: Ordering Information (Informative) Annex B: List of ICEA

44、Telecommunication Cable Standards (Informative) 1.3 Units In this Standard, metric (SI) units are used. Their approximate U.S. customary units are included where appropriate. Where approximate equivalents in alternate systems are included, they are provided for information only, and in most cases ar

45、e rounded off for measurement convenience. Unless otherwise specified, the Rounding Method of ASTM E 29 shall be used. Rounding of U.S. customary units may be adjusted for measurement convenience. 1.4 Definitions 1.4.1 Cable Classification In this Standard, communication cables are classified as one

46、 of the following types: 1.4.1.1 Composite Cables1 These cables contain more than one type of optical fiber. 1.4.1.2 Hybrid Cables1These cables contain both optical fibers for purposes of digital communications and metallic conductors for power transmission. Power levels may be higher than allowed i

47、n copper communications conductors or power-limited circuits. 1Note ICEA Standards prior to 2012 use definitions for composite and hybrid which are the opposite of those shown here. The change in definitions was made in the interest of harmonization with International documents and other National st

48、andards. It must be noted that the definition of composite in the National Electrical Code, 2011 and earlier, is consistent with the older ICEA definition. Due to this change users may see the terms used interchangeably.1.4.1.3 Dielectric Cables ANSI/ICEA S-119-741-2016 4 These cables contain no met

49、allic members or other electrically conductive materials. 1.4.1.4 Listed Cables Cables meeting the definition of “Listed” as defined by the NEC or other applicable code. 1.4.1.5 Metallic CablesCables which contain conductive members, not normally intended to be current-carrying, such as metallic strength members, sheaths, shields or armors. 1.4.1.6 Very-Low Temperature Cables Cables designed, specified, and qualified for use in applications where the low-end temperature extremes may reach -50 C. 1.4.2 Jackets and Sheaths In th
