Optical cable that provides physical attachment between two devices or between a device and a distribution panel. Contrast with trunk cable.
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
Physical connection between two devices on a switched fabric.
link incident
Interruption to link due to loss of light or other causes.
