Question

1)Both SMF optical cores are either step-index or graded-index. As such, SMF is susceptible to modal dispersion.

True

False

2)Select the correct statement(s) regarding fiber optic medium.

a. TIR is the principle that makes light communications travel efficiently through a fiber optic cable

b. MMF fiber can be step-indexed or graded-index

c. SMF has a greater bandwidth and throughput capability over MMF

d. ITU describes transmission windows associated with signal wavelength

e. All of the above are correct

3)Signals on coaxial cables are unbalanced. When compared to UTP, coaxial medium has higher bandwidth and data rate carrying capability compared to UTP.

True

False

4)A BER of 10E-6 tells you that there is a probability of having one bit error for every 1,000,000 bits sent.

True

False

5)Delay skew and crosstalk are only problems encountered when using coaxial cables for communications.

True

False

6)Guided UTP is configured as a balanced circuit.

True

False

False

6)Guided UTP is configured as a balanced circuit.

True

False

Explanation / Answer

1) False

Because modal dispersion is occured only in multimode fibers not in Single Mode Fibers.

2) e. All of the above are correct

3) True

4) True

5) False

There are many other problems also exists using coaxial cables

6) True
