Fiber optic cables are typically made of glass or plastic fibers encased in protective layers, often including steel or aramid yarn strength members to resist stretching and environmental stress . These strength members allow fiber optic cables to maintain tension over long spans with minimal sag, which is critical for maintaining signal integrity and preventing microbending losses . Outdoor fiber cables, especially aerial or OPGW (optical ground wire) types, are designed to handle mechanical loads and environmental factors like wind, ice, and temperature changes . Copper wires, on the other hand, are heavier and more ductile, and their sag is influenced primarily by their weight per unit length and the tension applied during installation . Copper conductors, especially in power lines, require careful tensioning to avoid excessive sag that could compromise clearance or safety. Unlike fiber optic cables, copper wires do not have internal strength members, so they tend to sag more under the same span and environmental conditions.
Fiber optic cables can communicate farther and faster than copper. The light signal is immune to electrical noise, ground potential

A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for fiber-optic communication in different applications, for exa
