ABSTRACT: This document details the Telcordia view of the generic requirements for Coaxial Distribution Cable intended for use in aerial,
underground and buried applications. Coaxial Distribution Cable is constructed with copper-clad aluminum center conductor insulated
with a suitable dielectric material. Insulations commonly used are expanded (foamed) polyethylene or periodically placed molded
polyethylene discs on the center conductor with air in between. The outer conductor or shield of a coaxial distribution cable consists
of an aluminum tube of desired thickness for semi-flexible and semi-rigid applications.
The outer conductor is covered with a plastic jacket. For underground installations, additional armor may be provided. For
corrosion protection, additional corrosion inhibitors could be added to the cable core. Coaxial cables in general do not need messenger
wire for aerial applications. However, for increased span length or areas of heavy ice loading and severe wind conditions, a messenger
wire is additionally required.
Revision 1 provides a list of Distribution Coaxial Cables that are considered to be the most popular sizes for the Local Exchange
Carriers (LECs) video and broadband networks. In addition, a list of various products is provided, based on attenuation grouping.
