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
农业和医学提供了重要启示。
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 农业和医学提供了重要启示。
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
农业和医学提供了重要启示。
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)
