SSCP Question #752: Real Exam Question with Answer & Explanation
The correct answer is A: Fiber Optic cable. Fiber optic cable transmits data as light pulses through glass or plastic fibers rather than as electrical signals through copper. Because light is not affected by electromagnetic interference (EMI) or radio frequency interference (RFI), fiber optic is immune to these effects. It
Question
Which of the following is immune to the effects of electromagnetic interference (EMI) and therefore has a much longer effective usable length?
Options
- AFiber Optic cable
- BCoaxial cable
- CTwisted Pair cable
- DAxial cable
Explanation
Fiber optic cable transmits data as light pulses through glass or plastic fibers rather than as electrical signals through copper. Because light is not affected by electromagnetic interference (EMI) or radio frequency interference (RFI), fiber optic is immune to these effects. It also supports much longer cable runs - often kilometers - compared to copper-based media like coaxial or twisted pair, which degrade significantly over shorter distances and are susceptible to EMI.
