Fiber U FTTA Quiz



True/False
Indicate whether the statement is true or false.
 

 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.
 

 8.

 9. 

In FTTA systems, fiber connects to a remote radio unit (RRU) at the top of the tower that connects to the antenna over _______.
A.
Radio waves
B.
Coax cable
C.
UTP cable
D.
Twinax cable
 

 10. 

Remote cell towers usually use _____ to connect to the phone system because it is the least expensive option.
A.

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
 

Multiple Response
Identify one or more choices that best complete the statement or answer the question.

 A.
Height
 B.
Antennas
 C.
Weight
 D.
