is transmitted as electrical pulses. (Cat 5, Cat 5e, Cat 6)
Attenuation - CORRECT ANSWER -The loss or weakening of a signal between two point
expressed in dBs (a ratio of signal sent and signal received)
AWG - CORRECT ANSWER -American wire gauge
Balanced twisted pair - CORRECT ANSWER -A type of wiring where a pair of
conductors continually twist inside the cable to reduce or eliminate the possibility of EMI from
other conductors in the cable (blue and blue white will be twisted together)
Capacitance - CORRECT ANSWER -the ability of a conductor to store electrical energy
,coaxial cable - CORRECT ANSWER -Cabling with a central metallic inner conductor and
a separated enclosed outer conductor by a dielectric material like a metallic braid
Crosstalk - CORRECT ANSWER -Unwanted transfer of a signals electromagnetic energy
(blue interfering with orange)
Impedance (Z) - CORRECT ANSWER -The total opposition that a circuit cable or
compound offers to the flow of altering current (measured in ohms)
Inductance - CORRECT ANSWER -The property of an electrical force field built around a
conductor when current flows through it
Insertion loss - CORRECT ANSWER -The signal loss resulting from the insertion of a
component (attenuation when a new signal is transmitted)
NVP - CORRECT ANSWER -Nominal velocity of propagation (coefficient used to
determine the speed of transmission relative to the speed of light)

current resistance and voltage
Ohms law formula - CORRECT ANSWER -V
I|R
Resistance - CORRECT ANSWER -A measurement of opposition a material offers to the
flow of direct current (measured in ohms)

fiber cable
Cladding - CORRECT ANSWER -The outer concentric glass layer that surrounds the
fibers core and has a lower index of refraction
Dispersion - CORRECT ANSWER -The loss of signal resulting from the scattering of
light pulses (The widening or spreading out of the modes)
Ferrule - CORRECT ANSWER -The alignment sleeve portion of an optical connector
FC - CORRECT ANSWER -Fiber connector
