Protection of Telecommunication Links From Radiation Effects.

This report describes measures that are intended to provide a baseline level of protection for links of public telecommunication networks PTNs against certain radiation effects. The measures are intended to establish foundation-level protecti n from damage caused by these radiation effects under typical geographic and local environmental conditions. The report should help define generally accepted practice which are intended to meet the needs of PTN. This report supplements NCS Technical Information Bulletin 93-9, Protection of Telecommunication Links from Physical Stress, June 1993, and forms the technical basis and rationale for the radiation effects protection measures. This report addresses the content of the proposed baseline standard, which will include protection from radiation effects on communication links interconnecting the centers of a PTN. The links are fiber optic or copper conductor cables of the trunk, feeder, and local distribution plant. They include connection and repeater points that are on pedestals or poles, or in manhone and that are not environmentally controlled. The terminations of the links in environmentally controlled buildings are included, but the buildings themselves and their contents are excluded.
