valokaapelilla
Valokaapeli, also known as fiber optic cable, is a type of data transmission medium that uses light pulses to carry information. It consists of thin strands of glass or plastic, thinner than a human hair, that are enclosed within a protective outer sheath. These strands, called optical fibers, are designed to reflect light internally, allowing it to travel long distances with minimal signal loss.
The principle behind valokaapeli is total internal reflection. Light is introduced into one end of the fiber
Valokaapeli is widely used in telecommunications, the internet infrastructure, and cable television networks. Its ability to
