NVP Nominal Velocity of Propagation
The difference in the amount of power received before
Insertion loss
and after something is inserted into the circuit.
Resistance is expressed in Ohms, and is the property of a
Resistance
conductor to resist the flow of electricity through it. V=IR
Is a property of an electromagnetic field built around a
Inductance conductor that opposes any change in the current flow
in a circuit
is a property of conductors that allows storage of
Capacitance electric charges when potential differences exist
between the conductors.
Impedance (V) Total opposition of current flow measured in Ohms
A standard rating that indicates the diameter of a wire,
American Wire Gauge
such as the conducting core of a coaxial cable or the
(AWG)
twisted pairs in a UTP cable.
one million hertz, especially as a measure of the
Megahertz (MHz)
frequency of transmissions
Approximately one million bits. Often used as a
Megabit (Mb)
measurement of data transfer throughput.
, The amount of data that can be transmitted over a
Bandwidth
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
Unwanted signal coupling from one permanent link to
Alien Crosstalk (AXT)
another
USOC Universal Service Order Code
Coaxial cable types Series-6 and Series-11
Series-6 uses BNC and F connectors
Coaxial connectors
Series-11 uses F and N connectors
Fiber connectors SC, ST, and SST(LC or
The glass or plastic shield around the core of a fiber-
optic cable. Cladding reflects light back to the core in
cladding patterns that vary depending on the transmission mode.
This reflection allows fiber to bend around corners
without impairing the light-based signal.
Larger core with multiple paths of light. Common for
backbone and horizontal cabling in buildings. OM2 -
Not recommended for new installs. OM3 - Higher
Multimode Fiber (MMF)
bandwidth. OM4 - Highest bandwidth for MMF.
2000m/6500ft limitation. 850 nm and 1300 nm
(nanometers)
Smaller core with only one path of lights. Horizontal,
riser, campus environments.
9 um core, 125 um cladding.
Singlemode Fiber
OS1 - LAN, tight buffered construction, 1310/1550 nm
OS2 - Outside Plant, 1310, 1490, 1550, 1625 nm

Multiple 250 um fibers bonded into a flat color coded
Ribbon Fiber
ribbon. Can splice a bunch at a time.
Fiber - Tight buffer diameter 900 um
