What is the major advantage of fiber optic media compared to traditional metallic cable media?
Correct answer: D. All of the above
- A. Higher bandwidth
- B. Lower signal loss
- C. Immunity to electromagnetic interference (EMI)
- D. All of the above
Explanation
The answer is (d) All of the above.Fiber optic media offers several advantages over traditional metallic cable media:Higher bandwidth: Fiber optic cables can transmit significantly more data per second than metallic cables. This is because they use light pulses to transmit information, which can travel much faster and farther than electrical signals.Lower signal loss: Fiber optic cables experience less signal loss over long distances compared to metallic cables. This is because light signals are less susceptible to attenuation (weakening) over distance.Immunity to electromagnetic interference (EMI): Fiber optic cables are not affected by EMI because they transmit light signals, which are not influenced by electromagnetic fields. This makes them ideal for use in environments with a lot of electrical noise, such as factories or power plants.In summary, fiber optic media offers significant advantages over traditional metallic cable media in terms of bandwidth, signal loss, and immunity to EMI.
