Which type of internet connection uses fiber optic cables for high-speed data transmission?

• A. Fiber optic
• B. Cable
• C. Digital subscriber line (DSL)
• D. Wireless

Answer: (A)

This question hinges on the transmission medium used to carry data. Fiber optic connections transmit data as light through glass or plastic fibers, which allows extremely high speeds and large bandwidth over long distances with minimal signal loss and little susceptibility to electrical interference. Because of this, fiber optic is the go-to for high-speed data transmission. In contrast, cable uses coaxial copper, DSL runs over copper telephone lines, and wireless sends signals through the air with radio waves, each with different speed and reliability characteristics and not driven by fiber optics.
