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
