25-pair color code - 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 - Answer -Blue, Orange, Green, Brown, Slate, White, Red, Black, Yellow, Violet,
Rose, Aqua
NVP - Answer -Nominal Velocity of Propagation
Insertion loss - Answer -The difference in the amount of power received before and after
something is inserted into the circuit.
Resistance - Answer -Resistance is expressed in Ohms, and is the property of a conductor to resist
the flow of electricity through it. V=IR
Inductance - Answer -Is a property of an electromagnetic field built around a conductor that
opposes any change in the current flow in a circuit
Capacitance - Answer -is a property of conductors that allows storage of electric charges when
potential differences exist between the conductors.
Impedance (V) - Answer -Total opposition of current flow measured in Ohms
American Wire Gauge (AWG) - 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) - Answer -one million hertz, especially as a measure of the frequency of
transmissions
Megabit (Mb) - Answer -Approximately one million bits. Often used as a measurement of data
transfer throughput.
Bandwidth - Answer -The amount of data that can be transmitted over a network in a given
amount of time.
Decibel (dB) - Answer -A unit used to compare the loudness of different sounds.
Crosstalk - Answer -when data bleeds from one pair to another in a cable
Alien Crosstalk (AXT) - Answer -Unwanted signal coupling from one permanent link to another
, USOC - Answer -Universal Service Order Code
Coaxial cable types - Answer -Series-6 and Series-11
Coaxial connectors - Answer -Series-6 uses BNC and F connectors
Series-11 uses F and N connectors
Fiber connectors - Answer -SC, ST, and SST(LC or
cladding - 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) - 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 - 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 - Answer -Multiple 250 um fibers bonded into a flat color coded ribbon. Can splice a
bunch at a time.
Fiber - Tight buffer diameter - Answer -900 um
Fiber - Acrylate coating diameter - Answer -250 um
OM1 - Answer -850 nm OFL - 200 MHz•km (3.5dB/km)
1300 nm - 400 MHz•km (1.5dB/km)
OM2 - Answer -850 nm OFL - 500MHz•km (3.5dB/km)
1300nm - 500MHz•km (1.5dB/km)
OM3 - Answer -850 nm OFL - 1500MHz•km (3.5dB/km)
850 nm RFL - 2000MHz•km (3.5dB/km)
1300 nm - 500MHz•km (1.5dB/km)
OM4 - Answer -850 nm OFL - 3500MHz•km (3.5dB/km)
850 nm RFL - 4700MHz•km (3.5dB/km)
