Chapter 9 Quiz - OSP Design
True/False
Indicate whether the statement is true or false.
1.
Fiber optic network designers should have a knowledge of electrical
power systems and hardware as well as communications design.
ANSWER: T
Since fiber networks require power and grounding, a knowledge of electrical power is a big advantage.
2. The first consideration for any network is choosing the proper fiber optic cable type.
ANSWER: F
Before
one can begin to design a fiber optic cable plant, one needs to
establish with the end user or network owner where the network will be
built and what communications signals it will carry.
3. Discussions of which is better – copper, fiber or wireless – are no longer relevant, as fiber is the only choice.
ANSWER: F
While
discussions of which is better – copper, fiber or wireless – has
enlivened cabling discussions for decades, it’s becoming moot.
Communications technology and the end user market, it seems, have
already made decisions that generally dictate the media and many
networks combine all three.
4. Most projects start with
the choice of a cable. Since OSP applications often use significant
lengths of cables, the cables can be made to order, allowing
optimization for that particular installation.t may be more cost
effective for the fiber optic cabling in many projects to be custom
designed and made.
ANSWER: T
Most projects start with the
choice of a cable. Since OSP applications often use significant lengths
of cables, the cables can be made to order, allowing optimization for
that particular installation.
5. Testing a fiber optic
installation may require testing three times, cable before
installation, each segment as installed and a final test of end-to-end
loss.
ANSWER: T
The process of testing any fiber optic cable
plant may require testing three times, testing cable on the reel before
installation, testing each segment as it is installed and finally
testing complete end to end loss of every fiber in the cable
plant.
Multiple Choice
Identify the choice that best completes the statement or answers the question.
6. Fiber optic network designers should have an in-depth knowledge of ________.
A. Fiber optic components and systems
B. Installation processes
C. All applicable standards, codes and any other local regulations
D. All of the above
ANSWER: D
These are all important areas for the knowledgeable fiber optic network designer.
7. The first requirement that must be considered for a new fiber optic project is ______.
A. The customer’s communications system requirements
B. Where the cable plant will be run
C. Whether it will be multimode or singlemode fiber
D. The customer’s budget
ANSWER: A
Any communications network must first be considered from the standpoint of the communications it should be transmitting.
8. Fiber Optic Network design involves ________.
A. Determining the types of communications systems involved
B. Planning the routes for all cabling or wireless
C. Choosing appropriate cabling and media
D. All of the above
ANSWER: D
Fiber optic network design involves all of the above and more!
9. When choosing components, most projects will start with the choice of a __________ .
A. Cable
B. Splice type
C. Connector
D. Cable hardware
ANSWER: A
The
choice of the cable usually comes first since the cable must be chosen
for the type of installation and the choice of most other hardware will
depend on the cable chosen.
10. Most premises networks
today should use _____ multimode fiber but backbone cables can contain
_____ fibers for future expansion.
A. OM1, OM3
B. OM1, singlemode
C. OM3, singlemode
D. OM2, OM3
ANSWER: C
As
in OSP design, consider the fiber choice first. Most premises networks
use multimode fiber, but many users now install hybrid cables with
singlemode fibers for future expansion. The 62.5/125 micron fiber (OM1
fiber) that has been used for almost two decades has mostly been
superceded by the new 50/125 laser-optimized fiber (OM3), as it offers
substantial bandwidth/distance advantages.
11. __________
of the cable plant is a necessary part of the design and installation
process for a fiber optic network that is often overlooked.
A. Planning
B. Documentation
C. CAD-CAM drawing
D. OTDR testing
ANSWER: B
Documentation
of the cable plant is a necessary part of the design and installation
process for a fiber optic network that is often overlooked.
12. What is the most helpful information you can have when trying to troubleshoot a cabling network for restoration?
A. Phone number of a fiber optic contractor
B. Loss data on each fiber
C. OTDR traces
D. Documentation
ANSWER: D
Documentation is the most helpful thing you can have when trying to troubleshoot a fiber network, especially during restoration.
Multiple Response
Identify one or more choices that best complete the statement or answer the question.
13. Metropolitan networks can involve which of the following systems?
A. CCTV surveillance cameras
B. Traffic monitoriing
C. Emergency services
D. Educational systems
ANSWER: A,B,C,D
Metropolitan
networks owned and operated by cities can carry a variety of traffic,
including surveillance cameras, emergency services, educational
systems, telephone, LAN, security, traffic monitoring and control and
sometimes even traffic for commercial interests using leased bandwidth
on dark fibers or city-owned fibers.
