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

Answer 1

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
