A composite cable combines which two conductor types?

• A. Fiber and Copper
• B. Fiber and Coax
• C. Fiber and Glass
• D. Copper and Aluminum

Answer: (A)

A composite cable combines fiber optic conductors with copper conductors in one cable assembly. This allows carrying high-speed data signals through the fiber while supplying power or low-voltage signals through the copper within a single run, simplifying installation and reducing conduit and routing space.

That makes fiber plus copper the best match, because it explicitly pairs an optical path with an electrical path in the same cable. The other options mix items that don’t provide both an optical path and an electrical path in one practical cable: coaxial cable is a different copper-based approach, glass isn’t a conductor, and aluminum paired with copper would still be metallic conductors without optical capability.
