NVP - Answer✔️✔️-Nominal Velocity of Propagation
Insertion loss - Answer✔️✔️-The difference in the amount of power received
before and after something is inserted into the circuit.
Resistance - Answer✔️✔️-Resistance is expressed in Ohms, and is the
property of a conductor to resist the flow of electricity through it. V=IR
Inductance - Answer✔️✔️-Is a property of an electromagnetic field built
around a conductor that opposes any change in the current flow in a circuit
Capacitance - Answer✔️✔️-is a property of conductors that allows storage of
electric charges when potential differences exist between the conductors.
Impedance (V) - Answer✔️✔️-Total opposition of current flow measured in
Ohms

American Wire Gauge (AWG) - Answer✔️✔️-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) - Answer✔️✔️-one million hertz, especially as a measure
of the frequency of transmissions
Megabit (Mb) - Answer✔️✔️-Approximately one million bits. Often used as
a measurement of data transfer throughput.
Bandwidth - Answer✔️✔️-The amount of data that can be transmitted over a
network in a given amount of time.
Decibel (dB) - Answer✔️✔️-A unit used to compare the loudness of different
sounds.
Crosstalk - Answer✔️✔️-when data bleeds from one pair to another in a
cable
Alien Crosstalk (AXT) - Answer✔️✔️-Unwanted signal coupling from one
permanent link to another
USOC - Answer✔️✔️-Universal Service Order Code
Coaxial cable types - Answer✔️✔️-Series-6 and Series-11
Coaxial connectors - Answer✔️✔️-Series-6 uses BNC and F connectors

cladding - Answer✔️✔️-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) - Answer✔️✔️-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 - Answer✔️✔️-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 - Answer✔️✔️-Multiple 250 um fibers bonded into a flat color
coded ribbon. Can splice a bunch at a time.
Fiber - Tight buffer diameter - Answer✔️✔️-900 um
Fiber - Acrylate coating diameter - Answer✔️✔️-250 um
OM1 - Answer✔️✔️-850 nm OFL - 200 MHz•km (3.5dB/km)
1300 nm - 400 MHz•km (1.5dB/km)
