2. Fiber color code Blue, Orange, Green, Brown, Slate,
White, Red, Black, Yellow, Violet, Rose,
Aqua
3. NVP Nominal Velocity of Propagation
4. Insertion loss The difference in the amount of pow-
er received before and after some-
thing is inserted into the circuit.
5. Resistance Resistance is expressed in Ohms, and
is the property of a conductor to resist
the flow of electricity through it. V=IR
6. Inductance Is a property of an electromagnetic
field built around a conductor that
opposes any change in the current
flow in a circuit
7. Capacitance is a property of conductors that allows
storage of electric charges when po-

tential differences exist between the
conductors.
8. Impedance (V) Total opposition of current flow mea-
sured in Ohms
9. American Wire Gauge (AWG) A standard rating that indicates the
diameter of a wire, such as the con-
ducting core of a coaxial cable or the
twisted pairs in a UTP cable.
10. Megahertz (MHz) one million hertz, especially as a mea-
sure of the frequency of transmis-
sions
11. Megabit (Mb) Approximately one million bits. Often
used as a measurement of data trans-
fer throughput.
12. Bandwidth The amount of data that can be trans-
mitted over a network in a given
amount of time.
13. Decibel (dB) A unit used to compare the loudness
of different sounds.
14. Crosstalk when data bleeds from one pair to
another in a cable
15. Alien Crosstalk (AXT) Unwanted signal coupling from one
permanent link to another

17. Coaxial cable types Series-6 and Series-11
18. Coaxial connectors Series-6 uses BNC and F connectors
Series-11 uses F and N connectors
19. Fiber connectors SC, ST, and SST(LC or
20. cladding The glass or plastic shield around the
core of a fiber-optic cable. Cladding
reflects light back to the core in pat-
terns that vary depending on the
transmission mode. This reflection al-
lows fiber to bend around corners
without impairing the light-based
signal.
21. Multimode Fiber (MMF) Larger core with multiple paths of
light. Common for backbone and
horizontal cabling in buildings. OM2
- Not recommended for new in-
stalls. OM3 - Higher bandwidth.
OM4 - Highest bandwidth for MMF.
2000m/6500ft limitation. 850 nm
and 1300 nm (nanometers)
22. Singlemode Fiber Smaller core with only one path of
lights. Horizontal, riser, campus envi-
ronments.
9 um core, 125 um cladding.
OS1 - LAN, tight buffered construc-
tion, 1310/1550 nm
OS2 - Outside Plant, 1310, 1490,
