An optical fiber cable transmits which of the following?

The correct answer is that an optical fiber cable transmits light waves. Optical fibers are designed to guide light from one point to another, allowing for the efficient transmission of data over long distances without significant loss of signal strength. This is made possible through the principle of total internal reflection, where light waves are reflected within the fiber's core, which is surrounded by a cladding material with a lower refractive index.

Light waves are produced by various sources, such as lasers or light-emitting diodes (LEDs), and are injected into the optical fiber. As the light travels through the fiber, it carries information in the form of modulated signals, enabling high-speed data transmission for telecommunications, internet connections, and other applications.

While photons, the fundamental particles of light, are involved in the transmission process, the term "light waves" more accurately describes the type of signal carried by the optical fiber. Electrons, on the other hand, are associated with electrical transmission in copper cables, and radio waves pertain to wireless communication methods, making them less relevant in the context of optical fiber cables.
