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