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