Solved
The speed at which data is transferred from one device to another. -
✔✔Data Transfer Rate
Bandwidth - ✔✔The width of a communication channel, measured in MB
p/s. It is the potential capacity of a medium, device or system.
UTP - ✔✔Unshielded Twisted Pair (4 Pair)
Attenuation (Loss of Signal Strength) - ✔✔The reduction of optical power
as it propagates through an optical fiber.
Near End/Far End Cross Talk (NEXT/FEXT) - ✔✔The undesired coupling
of signal energy from a transmitting pair to a receiving pair.
Permanent Link - ✔✔Consists of up to 90 m. of horizontal cabling, a
connection at each end, up to 2 m. of test equipment cord from the main
unit of the field connector to the local connection, and up to 2 m. of test
