25-pair color code - ✔White - Blue, orange, green,
brown, slate Red - Blue, orange, green, brown, slate
Black - Blue, orange, green,
brown, slate Yellow - Blue, orange,
green, brown, slate Violet - Blue,
orange, green, brown, slate
Fiber color code - ✔Blue, Orange, Green, Brown, Slate, White, Red,
Black, Yellow, Violet, Rose, Aqua
NVP - ✔Nominal Velocity of Propagation
Insertion loss - ✔The difference in the amount of power received
before and after something is inserted into the circuit.
Resistance - ✔Resistance is expressed in Ohms, and is the property
of a conductor to resist the flow of electricity through it. V=IR
,Inductance - ✔Is a property of an electromagnetic field built
around a conductor that opposes any change in the current flow in a
circuit
Capacitance - ✔is a property of conductors that allows storage of
electric charges when potential differences exist between the
conductors.
Impedance (V) - ✔Total opposition of current flow measured in
Ohms
American Wire Gauge (AWG) - ✔A standard rating that indicates
the diameter of a wire, such as the conducting core of a coaxial cable
or the twisted pairs in a UTP cable.
,Megahertz (MHz) - ✔one million hertz, especially as a measure of
the frequency of transmissions
Megabit (Mb) - ✔Approximately one million bits. Often used as a
measurement of data transfer throughput.
Bandwidth - ✔The amount of data that can be transmitted over a
network in a given amount of time.
Decibel (dB) - ✔A unit used to compare the loudness of different
sounds.
Crosstalk - ✔when data bleeds from one pair to another in a cable
Alien Crosstalk (AXT) - ✔Unwanted signal coupling from one
permanent link to another
USOC - ✔Universal Service Order Code
Coaxial cable types - ✔Series-6 and Series-11
Coaxial connectors - ✔Series-6 uses BNC and
, F connectors Series-11 uses F and N
connectors
Fiber connectors - ✔SC, ST, and SST(LC or
cladding - ✔The glass or plastic shield around the core of a fiber-
optic cable. Cladding reflects light back to the core in patterns that
vary depending on the transmission mode.
