jumper cable
Optical cable that provides physical attachment between two devices or between a device and
a distribution panel. Contrast with trunk cable.
laser
Light Amplification through Simulated Emissions of Radiation. A device that uses the
oscillation of atoms or molecules between energy levels to generate a narrow, finely focused
beam of light. The light has a single wavelength or narrow spectrum of wavelengths and is
matched in phase and frequency.
LED

indicators of hardware status or malfunctions.
latency
When used in reference to a Fibre Channel switching device, latency refers to the amount of
time elapsed between receipt of a data transmission at a switch's incoming F_Port (from the
originating node port) to retransmission of that data at the switch's outgoing F_Port (to the
destination N_Port). The amount of time it takes for data transmission to pass through a
switching device.
LIN
See link incident.
link
