JATC TELECOM Y1 | STRUCTURED CABLING FINAL
EXAM STUDY GUIDE | 100% ACCURATE PASS.
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 equipment cord from the remote connection to
the remote unit of the field tester.
Insertion Loss/Attenuation - A measure of how much a signal is reduced in amplitude or
strength as it is carried over a twisted pair or fiber.
Channel (including patch cords) - Consists of up to 90 m. of horizontal cabling, a work
area equipment cord, a telecommunications outlet, an optional consolidation connection
close to the work area, and 2 cross connections in the telecom room.
Performance requirements of Cat. 3 cables - 16 MHz
Performance requirement for Cat. 5 cables - 100 MHz
Performance requirements for Cat. 5e cables - 100 MHz
Performance requirements for Cat. 6 cables - 250 MHz
Performance requirements for Cat. 6e cables - 250 MHz
Performance requirements for Cat. 6a cables - 500 MHz
