Modal Bandwidth
Bandwidth for multimode fiber is referred to as modal bandwidth because it varies with the modal field (or core diameter) of the fiber. Modal bandwidth is specified in units of MHz per km, which indicates the amount of bandwidth supported by the fiber for a one km distance.
Network Diameter
Wire distance between two end stations in the same collision domain.
Redundant Power Supply (RPS)
A backup power supply unit that automatically takes over in case the primary power supply should fail.
A connector for
Switched Ports
Ports that are on separate collision domains or LAN segments.
TIA
Telecommunications Industry Association
Transmission Control Protocol/Internet Protocol (TCP/IP)
