Ljósleiðurum
Ljósleiðurum, commonly referred to as fiber optics, are thin strands of glass or plastic that transmit data in the form of light pulses. These cables are a cornerstone of modern telecommunications, enabling high-speed internet, telephone services, and data transmission over long distances. The principle behind ljósleiðurum lies in the phenomenon of total internal reflection. Light is introduced at one end of the fiber and bounces off the inner walls of the cable at a shallow angle, allowing it to travel great distances with minimal loss of signal.
The construction of ljósleiðurum involves a core, a cladding, and a protective outer jacket. The core is
