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)
