Glossary

(1) A link that can only carry a signal in one direction. (2) A fiber-optic cable or cord carrying a single fiber. Simplex cordage is mainly used for patch cords and temporary installations.

A term sometimes used to describe a single-fiber cable.

Data transmission over a circuit capable of transmitting in only one direction.

Optical fibers capable of carrying light in only one polarization.

Optical fibers capable of carrying light in only one polarization.

A circuit board containing the components needed for a computer that performs a prescribed task. A singleboard computer is often the basis of a larger piece of equipment that contains it.

An unbalanced circuit or transmission line, such as a coaxial cable (see also balanced line and unbalanced line).

A laser that emits a range of wavelengths small enough to be considered a single frequency.

A process in optical fiber manufacturing in which the soot created by heating silicon dioxide is compressed into glass to make the fiber preform.

A signal that varies over time in proportion to the sine of an angle. Alternating current (AC) is sinusoidal.

A light ray that does not intersect the fiber axis and generally enters the fiber at a very high angle.

The tendency of alternating current to travel on the surface of a conductor as the frequency increases.

A light-emitting diode (LED) that emits light from its flat surface rather than its side. These are simple and inexpensive and provide emission spread over a wide range.
