1.
|
The growing increase in mobile device data usage has driven cell providers to
install many new antennas.
|
|
2.
|
Wireless is not wireless.
|
|
3.
|
FTTA applications use field termination on cables to reduce cost and
inventory.
|
|
4.
|
Besides fibers for the signals, FTTA cables also usually contain copper wires
for powering the RRU and antenna.
|
|
5.
|
Rooftop antennas mounted on buildings generally connect over fiber to base band
units (BBUs) inside the building over fiber optics..
|
|
6.
|
Small cells or microcells are low powered antennas designed for small geographic
areas..
|
|
7.
|
Most OTDRs can resolve all the short cables used in FTTA, making it the
ideal test instrument.
|
Multiple Choice Identify the choice that best
completes the statement or answers the question.

reflectance, even damage connectors.
A. | Heat | B. | Water | C. | Dirt | D. | Wind |
|
|
12.
|
The condition of the fiber optic connector is first tested by
____________.
A. | Insertion loss | B. | OTDR | C. | Inspection for
dirt with a microscope | D. | VFL for bend
damage |
|
|
13.
|
Because of the difficulty of connecting to the cables at the top of the tower,
one tests tower cables by ____________.
A. | Doing all tests on the ground before installation | B. | Having a launch
cable long enough to reach the top of the tower | C. | Using a loopback at the top of the tower and
test with instruments on the ground | D. | Only using an
OTDR |
|
