What type of cabling uses optical pulses of light for data transmission?

The cabling that uses optical pulses of light for data transmission is fiber optic. This type of cabling transmits data by sending pulses of light through thin strands of glass or plastic fibers. The technology takes advantage of the principle of light transmission, which allows for higher bandwidths over greater distances compared to traditional copper cabling.

Fiber optic cables are renowned for their speed and efficiency, making them ideal for high-speed internet connections, telecommunications, and data center interconnectivity. The use of light pulses instead of electrical signals helps reduce interference and allows for faster data transmission rates, ensuring higher reliability in various networking applications.

This is distinctly different from coaxial, which uses a copper conductor to carry electrical signals, twisted pair cabling, which uses pairs of copper wires twisted together, and DSL, which is a technology that transmits data over existing telephone lines using electrical signals. Each of these alternatives has its own specific applications and limitations in terms of speed, distance, and susceptibility to interference compared to fiber optic technology.
