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.
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.
Fiber - Tight buffer diameter 900 um
Fiber - Acrylate coating diameter 250 um
OM1 850 nm OFL - 200 MHz•km (3.5dB/km)
1300 nm - 400 MHz•km (1.5dB/km)
OM2 850 nm OFL - 500MHz•km (3.5dB/km)
1300nm - 500MHz•km (1.5dB/km)
OM3 850 nm OFL - 1500MHz•km (3.5dB/km)
