BICSI INSTALLER 1 STUDY GUIDE WITH
COMPLETE SOLUTIONS 2026
◉ 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.
