Are optical cables all made of copper

No, optical (fiber-optic) cables are primarily made of glass or plastic fibers, not copper.

Fiber-optic cables transmit data using light signals through ultra-pure glass or plastic fibers, rather than electrical currents, which is the method used in copper cables . The core of a fiber-optic cable is a thin strand of glass or plastic that carries light, surrounded by cladding and protective coatings to maintain signal integrity and durability . These cables are designed for high-speed, long-distance data transmission and are immune to electromagnetic interference, unlike copper cables . While some fiber-optic cables may include copper elements, these are not for data transmission. Instead, copper may be integrated for power delivery, grounding, or cable tracing in hybrid designs, running alongside the optical fibers to power remote equipment like wireless access points or IP cameras . In standard pure fiber-optic cables, there is no metallic copper, and all data is transmitted via light, providing higher bandwidth, longer transmission distances, and enhanced security compared to copper wiring . In contrast, copper cables (such as twisted pair or coaxial cables) transmit data using electrical pulses through metal conductors, making them susceptible to electromagnetic interference and generally limiting their speed and distance compared to fiber-optic cables . Copper remains widely used for shorter-range or cost-sensitive applications, but fiber-optic cables are the preferred choice for high-performance networking.
