The function of adding iron wire to power poles for pulling optical cables
Guy wires can be attached to a pole to add strength that is necessary if the calculated load is greater than what the strength of the pole offers by itself. They offer counter-tension that stabilizes the pole against forces that could cause leaning or swaying. Most aerial fiber optic cables are installed by lashing to a steel messenger wire strung between poles, but there is a category of cables with special high-strength jacket designs called all-dielectric self-supporting (ADSS) cables. OPGW and OPPC cables are not a new concept. The first patents on such cables dates. The hardware serves multiple functions, including supporting conductors, providing insulation, terminating lines, and ensuring the structural integrity of the entire pole-mounted system. Power companies need permits and regulatory approvals to meet federal and local safety standards.
