Optical cables are composed of several copper wires

No, optical (fiber-optic) cables are not composed of copper wires; they are made of glass or plastic fibers that transmit data as light. Fiber-optic cables consist of a core, cladding, coating, strengthening fibers, and a protective jacket. The core, typically made of ultra-pure glass (silicon dioxide) or sometimes plastic, carries light signals, while the cladding surrounds the core to keep the light contained through total internal reflection.

The coating and buffer layers protect the fiber from physical damage, and additional layers like Kevlar or steel may be added for strength and environmental protection. Unlike copper cables, which transmit data using electrical currents, fiber-optic cables transmit data using light waves, allowing for higher bandwidth, faster speeds, and longer transmission distances without signal degradation. Fiber-optic cables are also lighter, corrosion-resistant, and more secure, making them ideal for long-distance communication, undersea cables, and high-speed internet infrastructure.

In summary, optical cables do not contain copper wires; their design relies on glass or plastic fibers to transmit information optically rather than electrically, which is fundamentally different from traditional copper wiring systems.
