Fiber optic cables are primarily designed to transmit data as pulses of light. This technology allows for the delivery of high-speed services, making it possible to transfer large amounts of data over long distances with minimal signal loss. The core of fiber optic cables is made of glass or plastic that guides the light signals, making them efficient for various telecommunications and internet services.

While there may be other choices that mention connectivity and other services, they do not encapsulate the essence of what fiber optics accomplish. The core functionality of fiber optic cables is solely focused on the rapid and efficient transmission of data, which is essential for modern communications.
