Which of the following is an advantage of fiber optic cables?

• A. Higher carrying capacity
• B. All of the above
• C. Less signal degradation
• D. Thinner and lightweight

Answer: (B)

Fiber optic cables use light to carry data, which gives them a very wide bandwidth, so they can handle more data at higher speeds. The light signals also experience very little attenuation over distance and aren’t affected by electromagnetic interference, so the signal degrades much less than with metal conductors. Physically, the glass or plastic fiber is extremely thin and lightweight, making cables thinner and lighter than many copper options for the same performance. Since all of these advantages are true, the best choice is the option that includes all of them.
