Introduction to Fiber Optics
What
are fiber-optics? “Fiber-optics are
hair-thin filaments of very pure glass or plastic used to transport pulses of
light, carrying vast amounts of data.
Fiber optic communications are different from any other data transmission
method, in that it does not use electricity to transmit information. Instead of
electrical signals, modulated light is used to quickly transmit data over long
distances through an insulated glass fiber. Fiber provides much faster data
transfer speeds when compared to traditional interconnection media such as
copper wire, coaxial cable or wireless. Fiber optics can support voice, video,
and data all at once over a single line.”
As stated on http://www.lus.org/site218.php. Fibers are better than metal wires because
there is a much less significant loss of signals and the fibers are not
affected by an electromagnetic interference.
Fibers are also used for lighting and can be wrapped in bundles that can
carry images.
