Attenuation Decrease of power in a signal along a cable, it is measured in logarithmic units deciBel,
(dB).
AWG American Wire Gauge; scale for diameter of conductors
Capacitance Is the property of a dielectric material in between conductors, producing that energy is
stored when a difference of electric potential is present in the conductors.
CSA Canadian Standards Association; organization that produces standards and then certifies
against them electric & electronic equipment
