A technology that uses glass (or plastic) threads (fibers) to transmit data.
A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated into light waves.
Fiber optics has many advantages over traditional copper communications lines:
The main disadvantage of fiber optics is that the cables are expensive to install.
In addition, they are more fragile than wire and are difficult to splice.
Fiber optics is a particularly hot technology for LAN.
In addition, telephone companies are steadily replacing traditional telephone lines with fiber optic cables. In the future, almost all communications will work on fiber optics.
