41、rd is to establish generic technical requirements that may be referenced by individual telecommunications cable specifications covering products intended for broadband outside plant use. The parameters covered provide material, construction, and performance requirements that are applicable to aircor

42、e, polyolefin insulated and jacketed cables of limited pair counts, including a variety of shield and jacket combinations. Because this Standard does not cover all details of individual cable design, it cannot be used as a single document for procurement of product. It is intended to be used in conj

43、unction with an individual product specification that provides complete design details for the specific cable type and designates the applicable performance requirements. Such individual cable specifications may be prepared either by the user or the manufacturer. The specification designated for pro

44、curement is at the option of the user. 1.2 SCOPE: This Standard covers mechanical and electrical requirements for aircore broadband twisted pair telecommunications cable with polyolefin insulated copper conductors. Broadband cables as described in this Standard are primarily intended to supply broad

45、band services from the remote switch to the customer premises. The remote switch in turn is normally supplied by fiber link from the central office. The reach of these systems is a function of the signal to noise ratio, deployed protocol and bit-rate, and may exceed 1000 m (3280 ft). These systems w

46、ill allow the simultaneous transmission of regular telephone services, computer, fax and several TV channels. The TV services may be interactive or may be High Definition TV. 1.3 OPTIONS AND INFORMATION: This Standard provides alternative choices for type of insulation, core assembly, color code, sh

47、eath design (shielding materials, single or double jackets, and jacket thicknesses and materials). One of the objectives of this Standard is to ensure compatibility with the Category 5e system requirements as specified in the TIA/EIA Standard 568-C.2 for commercial building telecommunications cablin

48、g, so that the standardized cables can be used as “Customer Owned Outside Plant Cables” or “Campus Cables”. These cables are intended to be installed aerially. When properly pressurized, they may also be installed in ducts or directly buried. ANSI/ICEA S-98-688-2012 2 This Standard is arranged in Se

49、ctions. Each Section covers one specific area of cable requirement and may be referenced as complete Sections or as individual paragraphs. Paragraphs in this Standard where the user may specify a particular option are listed below: 2.1 Conductor Size 3.2 Insulation Type 4.6 Self-Support (Figure 8) Cable 6.1 Shielding Systems 6.3 Shield Application 7.1 Inner Jacket 7.2.1 Outer Jacket (Material Type) 10.1.5 Length Marking 10.4 Pressurization 10.5.1 Physical Reel Protection 10.5.2 Pulling Eyes To assist the user in selection of options and to avoid pos
