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
1|Page
,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. This reflection allows fiber to bend around corners without
impairing the light-based signal.
Multimode Fiber (MMF) - Larger core with multiple paths of light. Common for
backbone and horizontal cabling in buildings. OM2 - Not recommended for new
installs. OM3 - Higher bandwidth. OM4 - Highest bandwidth for MMF.
2000m/6500ft limitation. 850 nm and 1300 nm (nanometers)
Singlemode Fiber - Smaller core with only one path of lights. Horizontal, riser,
campus environments.
9 um core, 125 um cladding.
OS1 - LAN, tight buffered construction, 1310/1550 nm
OS2 - Outside Plant, 1310, 1490, 1550, 1625 nm
3000m/9842ft limtations.
Ribbon Fiber - Multiple 250 um fibers bonded into a flat color coded ribbon. Can
splice a bunch at a time.
