Optical ground wire
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.

In underground line construction, longitudinally watertight cables with fillings made of gel or spring yarn should be used. Blind-mating solutions, such as the HEC coupling from R&M, help to prevent dirt ingress in above-ground cable laying. Fiber optic cables enable high-speed, long-distance data transfer, forming the backbone of modern communication. However, this does not mean every fiber optic installation is exempt from grounding requirements. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. Select the best installation method—direct burial, aerial, conduit, or underwater—based on your environment and future network needs.
