& VERIFIED CORRECT ANSWERS
PASSED 100%
25-pair color code - Correct Answer ✔✔ White - Blue, orange, green, brown, slate
Red - Blue, orange, green, brown, slate
Black - Blue, orange, green, brown, slate
Yellow - Blue, orange, green, brown, slate
Violet - Blue, orange, green, brown, slate
Fiber color code - Correct Answer ✔✔ Blue, Orange, Green, Brown, Slate, White, Red,
Black, Yellow, Violet, Rose, Aqua
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.
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 - Correct Answer ✔✔ Multiple 250 um fibers bonded into a flat color coded
ribbon. Can splice a bunch at a time.
Fiber - Tight buffer diameter - Correct Answer ✔✔ 900 um
Fiber - Acrylate coating diameter - Correct Answer ✔✔ 250 um
OM1 - Correct Answer ✔✔ 850 nm OFL - 200 MHz•km (3.5dB/km)
1300 nm - 400 MHz•km (1.5dB/km)
OM2 - Correct Answer ✔✔ 850 nm OFL - 500MHz•km (3.5dB/km)
1300nm - 500MHz•km (1.5dB/km)
