Communication optical cables do not contain copper

Contrary to popular belief, fiber optic cables do not contain copper. Instead, they consist primarily of glass or plastic fibers that transmit data using light signals. These fibers are surrounded by protective coatings made of materials such as polymer or epoxy resin. This guides optical signals via total internal reflection without conductive elements. Fiber optic cables have revolutionized data transmission. Because data travels as light rather than electricity, there is no inherent need for copper in standard fiber optic cables.
