True/False
Indicate whether the statement is true or
false.
|
|
|
1.
|
If the receiver power is too high, the receiver will overload and have high
bit-error-rate.
|
|
|
2.
|
If the receiver power is too low, the electrical noise in the receiver will
cause it to have high bit-error-rate.
|
|
|
3.
|
Attenuators should reduce the receiver power to around the middle of the
receiver's operating range.
|
|
|
4.
|
Attenuators are never sensitive to the type or size of fiber in the cable
plant.
|
Multiple Choice
Identify the choice that best completes the
statement or answers the question.

|
|
5.
|
The ________ of a fiber optic data link is a measure of the cable plant
attenuation that that link can tolerate.

range | d. | Bit error rate |
|
|
|
6.
|
The difference between the link power budget and the cable plant loss budget is
the link's ______.
a. | Link margin | b. | Overload | c. | Operating
range | d. | Attenuation |
|
|

8.
|
If a transmitter has an output of 0 dBm, the cable plant has a loss of 5
dB and the operating range of the receiver is -10 dBm to -30 dBm, which attenuator should be
chosen?
a. | No attenuator is needed | b. | 5 dB | c. | 15
dB | d. | 25 dB |
|
|
|
9.
|
If a transmitter has an output of 0 dBm, the cable plant has a loss of 15
dB and the operating range of the receiver is -10 dBm to -30 dBm, which attenuator should be
chosen?
a. | No attenuator is needed | b. | 15 dB | c. | 20
dB | d. | 25 dB |
|
