This guide is intended for fiber optic cables designed for use in power generating stations and industrial facilities, in both the outside plant environment and indoor applications--the latter with adequate consideration for requirements of the National Electrical Code (NEC). It is not the intention of this guide to establish requirements for cables designed for installation in a high voltage environment, such as optical ground wire and all-dielectric, self-supporting. These applications are covered by other IEEE documents (IEEE Std 1138(TM) and IEEE Std 1222(TM)).
