An Optical Ground Wire (OPGW) is a dual-function cable installed at the top of high-voltage transmission lines. It combines grounding and lightning protection with embedded optical fibers for telecommunications. The cable contains a tubular structure housing optical fibers, surrounded by layers of steel and aluminum wires. The conductive layers bond towers to earth ground and shield power conductors from lightning, while the optical fibers provide high-speed data transmission for utility control, voice, or leased communication services .
Choosing the right OPGW model depends on fiber count requirements, mechanical load, span length, and environmental conditions. AlumaCore is ideal for rugged, high-tension applications, HexaCore for high fiber protection with multi-layer stranded design, CentraCore for compact high-density installations, and MASS cable for self-supporting telecommunications without electrical grounding. Manufacturers like AFL provide detailed specifications, WIR files for sag and tension calculations, and custom solutions to match specific project needs .

An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and telecommunications. An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire. The OPGW cable is run between the tops of high-voltage electricity pylons. The conductive part of the cable serves to bond adjacent tow
