QUESTION 9

Which of the following is used most often in LANs for fiber transmission links?

850 nm single-mode fiber

850 nm multimode fiber

850 nm multimode-mode fiber

1,550 nm single-mode fiber

4

5

None of these

Explanation / Answer

5)------------------

24 = 16 ,so 4 bit per clock cycle

6)----------------

100GBASE-SR because it provides 100 GB link and 200 meter

7)_----------------

Switches do not know the entire data link between the source host and the destination host.

8-----------------------

to keep cost low because 850nm cable not for higher distance and multimode reduce the cost.

9)---------------------------

850 nm multimode fiber because of used for shorter length, cost-effective and high speed
