Violet, Rose, Aqua
Question 3.
NVP
Correct Answer: Nominal Velocity of Propagation
Question 4.
Insertion loss
Correct Answer: The difference in the amount of power received before and
after something is inserted into the circuit.
Question 5.
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
Question 6.
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
Question 7.
Capacitance
Correct Answer: is a property of conductors that allows storage of electric
charges when potential differences exist between the conductors.
,Question 8.
Impedance (V)
Correct Answer: Total opposition of current flow measured in Ohms
Question 9.
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.
Question 10.
Megahertz (MHz)
Correct Answer: 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.
Question 11.
Bandwidth
Correct Answer: The amount of data that can be transmitted over a network in
a given amount of time.
Question 12.
Decibel (dB)
Correct Answer: A unit used to compare the loudness of different sounds.
Question 13.
Crosstalk
Correct Answer: when data bleeds from one pair to another in a cable
Question 14.
Alien Crosstalk (AXT)
Correct Answer: Unwanted signal coupling from one permanent link to another
Question 15.
USOC
Correct Answer: Universal Service Order Code
, Question 16.
Coaxial cable types
Correct Answer: Series-6 and Series-11
Question 17.
Coaxial connectors
Correct Answer: Series-6 uses BNC and F connectors Series-11 uses F and N
connectors
Question 18.
Fiber connectors
Correct Answer: SC, ST, and SST(LC or
Question 19.
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.
Question 20.
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)
Question 21.
Singlemode Fiber
Correct 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 -✓✓Multiple 250 um fibers bonded into a flat color coded
ribbon. Can splice a bunch at a time.
Question 22.
Fiber - Tight buffer diameter
Correct Answer: 900 um
