Fiber optic wire are cables made up of thin strands of glass or plastic, each about the thickness of a human hair. These strands carry data in the form of light signals, enabling incredibly fast and efficient communication over long distances. No mater how accurate of a locate you have it's still gutwrenching diging near that stuff. 100 grand minimum if you dig one up. Unlike copper wires, which are limited by lower data transmission speeds, shorter transmission distances, and higher susceptibility to electromagnetic interference, fiber optic cables offer unparalleled performance and can. Fibre optic technology is an effective cabled-based communication system. Using a fiber size chart simplifies cable selection.
