Question:
NVP
Answer:
Nominal Velocity of Propagation
Question:
Insertion loss
Answer:
The difference in the amount of power received before and after something is inserted into the circuit.
Question:
Resistance
Answer:
Resistance is expressed in Ohms, and is the property of a conductor to resist the flow of electricity
through it. V=IR
Question:
Inductance
Answer:
Is a property of an electromagnetic field built around a conductor that opposes any change in the
current flow in a circuit
,Question:
Capacitance
Answer:
is a property of conductors that allows storage of electric charges when potential differences exist
between the conductors.
Question:
Impedance (V)
Answer:
Total opposition of current flow measured in Ohms
Question:
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.
Question:
Megahertz (MHz)
Answer:
one million hertz, especially as a measure of the frequency of transmissions
Question:
Megabit (Mb)
Answer:
Approximately one million bits. Often used as a measurement of data transfer throughput.
Question:
Bandwidth
Answer:
The amount of data that can be transmitted over a network in a given amount of time.
Question:
Decibel (dB)
Answer:
A unit used to compare the loudness of different sounds.
, Question:
Crosstalk
Answer:
when data bleeds from one pair to another in a cable
Question:
Alien Crosstalk (AXT)
Answer:
Unwanted signal coupling from one permanent link to another
Question:
USOC
Answer:
Universal Service Order Code
Question:
Coaxial cable types
Answer:
Series-6 and Series-11
Question:
Coaxial connectors
Answer:
Series-6 uses BNC and F connectors Series-11 uses F and N connectors
Question:
Fiber connectors
Answer:
SC, ST, and SST(LC or
Question:
cladding
Answer:
The glass or plastic shield around the core of a fiberoptic 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.
