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.
• Megahertz (MHz) -✓✓one million hertz, especially as a measure of the
frequency of transmissions


Question 10.
Megabit (Mb)

Correct Answer: 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.
• 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)


Question 20.
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.


Question 21.
Ribbon Fiber

Correct Answer: 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
