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 onto light waves. Fiber optics has several advantages over traditional metal communications lines
Speed : Fiber optic networks operate at high speeds - up into the gigabits
Bandwidth : large carrying capacity
Distance : Signals can be transmitted further without needing to be "refreshed" or strengthened.
Resistance : Greater resistance to electromagnetic noise such as radios, motors or other nearby cables.
Maintenance : Fiber optic cables costs much less to maintain..
