ICEA S-120-742-2016 1 PART 1 INTRODUCTION 1.1 SCOPE This Standard covers performance requirements for limited power hybrid copper and fiber communications cables intended for use in the buildings, or for short distances external to the building of communications users. The optical fiber is in
25、tended for communications use while the copper conductors are intended for limited power applications in accordance with Articles 725 and 800 of the National Electric Code (NEC) ANSI/NFPA 70. Typically, these cables utilize conductor sizes that range from 10 AWG to 20 AWG. Generally these cables are
26、 limited to a maximum of 100 VA. However, refer to NEC document for detailed requirements. Materials, constructions and performance requirements are included in the Standard, together with applicable test procedures. Products covered by this standard are intended only for operation under conditions
27、normally found in communication systems. Typically, these products are installed both in exposed areas (surface mounted to walls or building baseboards or in non-stationary configurations) and in concealed areas (within walls, attics, etc.), with or without external protection (such as conduit), dep
28、ending upon product type and specific use. These products normally convey communications signals (voice, video, data, etc.) from place to place within a building. Products covered by this Standard may be factory terminated with connectors or splicing modules. This standard is intended to serve as a
29、reference to the most recent appropriate standards; ICEA S-83-596 for optical fiber communications cables intended for indoor use, ICEA S-104-696 for optical fiber communications cables intended for indoor-outdoor use and UL13 for Power Limited Circuit Cables with the addition of any additional requ
30、irements to ensure a functional cable design. This standard is written from the application perspective of an Distributed Antenna System (DAS), however, other use cases that involve hybrid fiber/copper in a Limited Power application as defined by the National Electric Code, are considered to apply.

33、ified in Table 7-2. Standard Minimum Bend Diameter Interconnect All Other Cables Unloaded Condition (Installed): 50 mm 20 x Cable OD Loaded Condition (During Installation): 100 mm 40 x Cable OD For very small cables, manufacturers may specify a fixed cable minimum bend diameter (e.g., 300 mm) that i
34、s 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 diameter and bending in the direction of the preferential bend. Products covered by this Standard shall comply
35、 with the pertinent Fire Resistance Code(s) described in Section 1.9. 1.2 GENERAL This publication is arranged so that cables may be selected from numerous constructions covering a broad range of installation and service conditions. Parts 2 and 3 designate the materials, material characteristics, di
36、mensions and tests applicable to the particular component. Part 4 covers assembly, cabling, and identification of the individual optical fiber. Part 5 includes cable coverings. Part 6 provides other pertinent requirements not otherwise addressed by Parts 1 through 5 or by Parts 7 and 8 of this Stand
37、ard. ICEA S-120-742-2016 3 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 1 through 6 and Part 7, the provisions of Part 7 apply. Part 8 contains routinel
38、y specified optical performance, test methods and requirements for finished cables. Part 9 contains cross-references to other standards and publications.

39、ns Cable Standards Annex D Informative Maximum Tension on Cable Conductors Example 1.3 UNITS In this Standard, metric (SI) units are used. Where approximate equivalents in alternate systems are included, they are provided for information only, and in most cases are rounded off for measurement conven
40、ience. 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. ICEA P-57-653 is a useful guide for metric units used in this publication. 1.4 DEFINITIONS 1.4.1 Cable Classification Products covered in t
41、his Standard shall be classified according to their level of mechanical and thermal robustness, as declared by the manufacturer. The classification of a particular cable design, along with its fire rating (see 1.4.2), determines the appropriate testing and acceptance requirements. Cable classificati
42、ons are defined below. 1.4.1.1 Backbone Cables Cables which consist of a plurality of optical fibers in designs having a higher degree of robustness as compared to interconnect cables. Backbone cables are suitable for connections between telecommunications rooms, equipment rooms and entrance facilit
43、ies. Backbone cables, typically, are sufficiently robust for placement in riser shafts, cable racks, or cable trays. Backbone cables are further classified according to their fire rating (see section 1.4.2) Vertical backbone cable: A backbone cable to be used in vertical applications where the weigh
44、t of the cable substantially contributes to the cable environment. This cable may have a higher tensile rating than horizontal backbone cables. Cables installed in vertical riser shafts are a common example. ICEA S-120-742-2016 4 Horizontal backbone cable: A backbone cable to be used primarily in ho
45、rizontal applications. This cable may have a tensile rating which is dependent on its size or fiber count and may be lower than that of vertical backbone cable. Cables installed in horizontal runs or horizontal air-handling spaces are common examples. Distribution Cables: A backbone cable design in
46、which multiple fibers (typically tight buffered) are contained under one protective jacket. Breakout Cables: A backbone cable design in which each fiber (typically tight buffered) is individually reinforced and jacketed, all surrounded by one common overall jacket. 1.4.1.3 Composite Cables1 Cables w
47、hich contain more than one type of optical fiber. 1.4.1.5 Hybrid Cables1 Cables having both optical fibers and metallic conductors. For this standard the metallic conductors are intended to provide power. 1.4.1.6 Metallic Cables Cables which contain conductive members, not normally intended to be cu
48、rrent-carrying such as metallic strength members, sheaths, shields, or armors. . 1.4.2 Fire Rating of Cables2 _ 1 ICEA Standards prior to 2012 use definitions for composite and hybrid which are the exact opposite of those shown here. The change in definitions was made in the interest of harmonizatio
49、n with International documents and other National Standards. It must be noted that the definition of composite in the National Electrical Code, 2011 and earlier, are consistent with the older ICEA definition. Due to this change, users may see the terms used interchangeably. Regarding the definition for hybrid, as altered above: IEC uses a definition which encompasses metallic conductors used for all purposes not just communic
