BICSI - Installer 1 – Exam Review | UPDATED ACTUAL Exam
Questions and CORRECT Answers | 100% Accurate

Question 1.
Insertion loss

Correct Answer: The difference in the amount of power received before and
after something is inserted into the circuit.


Question 2.
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.


Question 3.
Bandwidth

Correct Answer: The amount of data that can be transmitted over a network in
a given amount of time.


Question 4.
Decibel (dB)

Correct Answer: A unit used to compare the loudness of different sounds.


Question 5.
Crosstalk

Correct Answer: when data bleeds from one pair to another in a cable


Question 6.
Alien Crosstalk (AXT)

Correct Answer: Unwanted signal coupling from one permanent link to another


Question 7.
USOC

Correct Answer: Universal Service Order Code


Question 8.
Fiber connectors

Correct Answer: SC, ST, and SST(LC or

,Question 9.
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.


Question 10.
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)


Question 11.
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.


Question 12.
Ribbon Fiber

Correct Answer: Multiple 250 um fibers bonded into a flat color coded ribbon.
Can splice a bunch at a time.


Question 13.
Fiber - Tight buffer diameter

Correct Answer: 900 um


Question 14.
Fiber - Acrylate coating diameter

Correct Answer: 250 um


Question 15.
OM1

Correct Answer: 850 nm OFL - 200 MHz•km (3.5dB/km) 1300 nm - 400 MHz•km
(1.5dB/km)

, Question 16.
OM2

Correct Answer: 850 nm OFL - 500MHz•km (3.5dB/km) 1300nm - 500MHz•km
(1.5dB/km)


Question 17.
OM3

Correct Answer: 850 nm OFL - 1500MHz•km (3.5dB/km) 850 nm RFL -
2000MHz•km (3.5dB/km) 1300 nm - 500MHz•km (1.5dB/km)


Question 18.
OM4

Correct Answer: 850 nm OFL - 3500MHz•km (3.5dB/km) 850 nm RFL -
4700MHz•km (3.5dB/km) 1300 nm - 500MHz•km (1.5dB/km)
• Modal Distortion -✓✓A light distortion problem unique to MMF fiber- optic
cable. Happens when light signals are sent at the same time.


Question 19.
chromatic dispersion

Correct Answer: The broadening of a pulse due to different propagation
velocities of the spectral components of the light pulse. Begins at the light
source


Question 20.
Straight Tip (ST)

Correct Answer: One of the most common fiber-optic connectors, similar in
style to the BNC connector in coax


Question 21.
subscriber connector (SC)

Correct Answer: A square snap coupling for fiber-optic cable, about 2.5 mm
wide, used for cable-to-cable connections or to connect cables to network
devices. It latches with a push-pull action similar to audio and video jacks.


Question 22.
Typical balanced twisted pair cable

Correct Answer: 100 Ohms UTP 4 pairs blue, orange, green, brown (tip/ring)
