[ noun ]
the transmission of light signals via glass fibers
<noun.communication>

Fiber optics \Fi"ber op`tics\,, n.
that branch of optics which studies the transmission of light
through thin transparent fibers.

Note: Light transmission through optical fibers has become an
important means of data and telephone signal
transmission, in some areas superseding the carrying of
vioce and data signals through electrical pulses over
copper wire. It is also used for directly carrying
images from otherwise inaccessible locations, as from
inside the body, for medical procedures. Light
transmission via fiber optics for data transmission
uses an {optical fiber} made of specially purified
glass with low light absorption characteristics.
