Which of the following are characteristics of transferring data using fiber as the medium? (Select TWO).

Question

Options

• AFiber can transmit data the farthest distance without requiring a repeater
• BFiber is the least susceptible to EMI
• CFiber is the most susceptible to changes in temperature and humidity, which can cause varying
• DFiber can transmit power as well as data, which will lead to cost savings
• EFiber is the least expensive means of transmitting data

• A
  86% (32)
• C
  3% (1)
• D
  3% (1)
• E
  8% (3)

Explanation

Fiber optic cable has two key advantages: (1) it supports very long transmission distances - up to tens of kilometers without a repeater - far exceeding copper cables; and (2) it transmits data as light pulses, making it completely immune to electromagnetic interference (EMI). Fiber does not transmit electrical power, is not temperature-sensitive in typical deployments, and is generally more expensive than copper.
