Question 26

True or false, Is fiber immune to EMI?

Answer 26

True

Question 27

Is Multimode fiber better for long distances? And Why?

Answer 27

Mutimode is better for short distances due to the wider core. Which allows more to reflect through over longer distances

Question 28

Does single-mode fiber suffer from delay distortion?

Answer 28

No, single-mode fiber only uses one mode of light due to the small core.
