Question

Accepted Answer

Optical fiber is a type of cable made of glass or plastic that transmits data using light instead of electricity.

Optical fiber is used for high-speed internet, cable TV, and telephone services.
It is made up of a core, cladding, and buffer coating.
The core is where the light travels, and the cladding keeps the light inside the core.
The buffer coating protects the fiber from damage.
Optical fiber is more efficient and has higher bandwidth than traditional copper cables.
It is also immune to electromagnetic interference and can transmit data over longer distances.
Examples of optical fiber include single-mode fiber and multi-mode fiber.
