Answers To Chapter Questions
Chapter 3 Quiz - Networks
TRUE/FALSE
1. ANS: T
Fiber can transport more information longer distances in less time than any other communications medium,
2. ANS: F
FTTH
is cost effective today because of the demand for high speed digital
services in the home and the development of lower cost PON networks.
MULTIPLE CHOICE
3. ANS: A
Electrical interference is a problem in many industrial applications and fiber's immunity to EMI is important.
4. ANS: B
Centralized
fiber networks have all the electronics in the computer room and at the
user location. No intermediate hubs or switches are required, so no
telecom closet (or room as they call it now) is necessary.
5. ANS: B
Media converters convert copper to fiber or even multimode to singlemode fiber.
MULTIPLE RESPONSE
6. ANS: A, B, C, D
All these answers are advantages of using optical fiber.
7. ANS: A, B, C, D
Fiber
is used for backbones for all these networks, including cell phones for
its bandwidth/distance advantage making it lower cost.
