POVZETEK - Elektrodistribucijska in prenosna podjetja uporabljajo za gradnjo komunikacij za potrebe obratovanja in vodenja energetskih omrežij najbolj pogosto kar lastno infrastrukturo. Optične vodnike tako nameščajo na nadzemne daljnovode kot samonosilne kable, jih ovijajo okoli strelovodnih ali faznih vodnikov ter zamenjajo strelovodno vrv ali fazni vodnik s tako, ki ima vgrajena optična vlakna. Najbolj pogost način gradnje optičnega omrežja na visokonapetostnih daljnovodih (110 kV ali več) je v tehnologiji OPGW (Optical Power Ground Wire), kjer so optična vlakna umeščena v strelovodni vrvi daljnovoda.

ABSTRACT - Power distribution and transmission companies most often use their own infrastructure to establishe communications for the needs of operating and managing energy networks. Optical fibers are installed on overhead power lines as self-supporting cables, wrapped around ground wire or phase conductor, or the conductor or ground wire have built-in optical fibers. The most common way of building an optical network on high-voltage transmission lines (of 110kV or more) is OPGW (Optical Power Ground Wire), where optical fibers are placed in the ground wire of the power line.
