OPGW cable is a dual-functioning cable designed to replace traditional overhead ground wires on transmission lines, providing fiber optics for telecommunications alongside electrical grounding capabilities. It contains optical fibers protected inside an aluminum or steel casing to withstand mechanical stresses from wind and faults. Various OPGW cable types include those with aluminum clad stainless steel tubes, stranded tubes, or central tubes to house fiber counts up to 48. Benefits include communication pathways with high reliability alongside electrical grounding functions. OPGW cable is used on power lines and telecom networks for voice, video, data and SCADA.
