Overhead fiber optic cable should adopt a galvanized steel strand with the specification of 7/2. 2mm as the suspension wire. Bynet GYTC8S/GYTC8A Figure-8 self-supporting optical fiber cables are designed for aerial deployments, offering both fiber transmission and mechanical support in a single. Corning stranded loose tube cables with corrugated steel tape armoring are designed for outdoor use for campus, city and intercity backbones in duct and direct burial installations. The steel strand is suspended, and the double-sided plastic-coated corrugated steel belt forms excellent flattening resistance.
