7、porting Fiber Optic Cable.) All-dielectric self-supporting (ADSS) fiber optic cables are being installed throughout the power utility industry. Because of the unique service environment and design of these cables, many new requirements are necessary to ensure proper design and application of these c
8、ables. In order to develop an industry-wide set of requirements and tests, the Fiber Optic Standards Working Group, under the direction of the Fiber Optic Subcommittee of the Communications Committee, brought together the expertise of key representatives from throughout the industry. These key peopl
9、e are from each manufacturer of ADSS cables and a cross sec- tion of the end users. All manufacturers and all known users were invited to participate in preparing this standard. The preparation of this standard occurred over a period of several years, and participation changed through- out that time
10、 as companies and individuals changed interests and positions. Effort was always made to include key individuals from each and every manufacturing concern, major user groups, and consulting firms. Membership and participation was open to everyone who had an interest in the standard, and all involvem
11、ent was encouraged. This worldwide representation helps to ensure that this standard reflects the entire industry. As ADSS fiber optic cables are a new and changing technology, the working group is continuing to work on new revisions to this standard as the need arises. Notice to users Errata Errata

Overview 1.1 Scope This standard covers the construction, mechanical, electrical, and optical performance, installation guidelines, acceptance criteria, test requirements, environment
29、al considerations, and accessories for an all-dielectric, nonmetallic, self-supporting fiber optic (ADSS) cable. The ADSS cable is designed to be located primarily on overhead utility facilities. The standard provides both construction and performance requirements that ensure within the guidelines o
30、f the standard that the dielectric capabilities of the cable components and maintenance of optical fiber integ- rity and optical transmissions are proper. This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety issues asso
31、ciated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. 2. ADSS cable and components 2.1 Description The ADSS cable shall consist of coated glass optical
32、 fibers contained in a protective dielectric fiber optic unit surrounded by or attached to suitable dielectric strength members and jackets. The cable shall not con- tain metallic components. The cable shall be designed to meet the design requirements of the optical cable under all installation cond
33、itions, operating temperatures, and environmental loading. 2.2 Support systems a)ADSS cable shall contain support systems that are integral to the cable. The purpose of the support system is to ensure that the cable meets the optical requirements under all specified installation con- ditions, operat
34、ing temperatures, and environmental loading for its design life. This standard excludes any “lashed” type of cables. Authorized licensed use limited to: Tsinghua University Library.

35、OR ALL-DIELECTRIC 2Copyright 2004 IEEE. All rights reserved. b)The basic annular construction may have aramid or other dielectric strands or a channeled dielectric rod as a support structure. In addition, other cable elements, such as central members, may be load bearing. c)Figure-8 constructions ma
36、y have a dielectric messenger and a fiber optic unit, both of which share a common outer jacket. In addition, other cable elements, such as central members, may be load bearing. d)Helically stranded cable systems may consist of a dielectric optical cable prestranded around a dielectric messenger. e)
37、The design load of the cable shall be specified so that support hardware can be manufactured to per- form under all environmental loading conditions. For zero fiber strain cable designs, the design load is defined as the load at which the optical fibers begin to elongate. For other cable designs, th
38、e design load is defined as the load at which the measured fiber strain reaches a predetermined level. f)Other designs previously not described are not excluded from this specification. 2.3 Fiber optic cable core The fiber optic cable core shall be made up of coated glass optical fibers housed to pr
39、otect the fibers from mechanical, environmental, and electrical stresses. Materials used within the core shall be compatible with one another, shall not degrade under the electrical stresses to which they may be exposed, and shall not evolve hydrogen sufficient to degrade optical performance of fibe
40、rs within the cable. 2.3.1 Fiber strain allowance The cable core shall be designed such that fiber strain does not exceed the limit allowed by the cable manu- facturer under the operational design limits of the cable. Maximum allowable fiber strain will generally be a function of the proof test leve
41、l and strength and fatigue parameters of the coated glass fiber. 2.3.2 Central structural element If a central structural element is necessary, it shall be of reinforced plastic, epoxiglass, or other dielectric material. If required, this element shall provide the necessary tensile strength to limit
42、 axial stress on the fibers and minimize fiber buckling due to cable contraction at low temperatures. 2.3.3 Buffer tube filling compound Loose buffer tubes shall be filled with a suitable compound compatible with the tubing material, fiber coat- ing, and coloring to protect the optical fibers and pr
43、event moisture ingress. 2.3.4 Cable core filling/flooding compound The design of the cable may include a suitable filling/flooding compound in the interstices to prohibit water migration along the fiber optic cable core. The filling compound shall be compatible with all components with which it may
44、come in contact. 2.3.5 Binder/tape A binder yarn(s) and/or a layer(s) of overlapping nonhygroscopic tape(s) may be used to hold the cable core elements in place during application of the jacket.

All rights reserved.3 2.3.6 Inner jacket A protective inner jacket or jackets of a suitable material may be applied over the fiber optic cable core, iso- lating the cable core from a
46、ny external strength elements and the cable outer jacket. 2.4 Optical fibers Single-mode fibers, dispersion-unshifted, dispersion-shifted, or nonzero dispersion-shifted, and multimode fibers with 50/125 mm or 62.5/125 mm core/clad diameters are considered in this standard. The core and the cladding
47、shall consist of glass that is predominantly silica (SiO2). The coating, usually made from one or more plastic materials or compositions, shall be provided to protect the fiber during manufacture, handling, and use. 2.5 Buffer construction The individually coated optical fiber(s) or fiber ribbon(s)
48、may be surrounded by a buffer for protection from physical damage during fabrication, installation, and performance of the ADSS. Loose buffer or tight buffer construction are two types of protection that may be used to isolate the fibers. The fiber coating and buffer shall be strippable for splicing
49、 and termination. 2.5.1 Loose buffer Loose buffer construction shall consist of a tube or channel that surrounds each fiber or fiber group. The inside of the tube or channel shall be filled with a filling compound. 2.5.2 Tight buffer construction Tight buffer construction shall consist of a suitable material that comes in contact with the coated fiber. 2.6 Color coding Color coding is essential for identifying individual optical fibers and groups of optical fibers. The colors shall be in accordance with TIA/EIA 598-A-1995 B43.1 2.6.1 Color performance The original color c
