scope:

This standard presents engineering design procedures for the electrical protection of telecommunication facilities serving electric supply locations through the use of metallic wire-line components in part of the telecommunication circuit and optical fiber systems in the remainder of the telecommunication circuit. Other telecommunication alternatives such as radio and microwave systems are excluded from this document.

Purpose

This standard presents workable methods that can be used with greater reliability to improve the electrical protection of telecommunication facilities serving electric supply locations through the use of metallic wire-line components in part of the telecommunication circuit and optical fiber systems in the remainder of the telecommunication circuit. Hybrid applications have an equipment junction between the metallic wireline and the fiber cable, i.e., a wire-line-fiber cable junction (CFJ).
