Identifying the Disadvantage of Fiber Optic Cable

When evaluating the options provided to determine the disadvantage of using fiber optic cable, we can analyze each choice:

1. Small Size: This is generally an advantage, as the small diameter of fiber optic cables allows for easier installation and placement.
2. Fastest Transmission Rate: Fiber optic cables are known for their high-speed data transmission capabilities, which is a significant advantage rather than a disadvantage.
3. High Attenuation: This is considered one of the disadvantages of fiber optic cables. Although fiber optics can transmit data over long distances, they can still suffer from attenuation, meaning that the signal can weaken over long runs without repeaters or amplifiers.
4. Immune to EMI (Electromagnetic Interference): This is also an advantage, as fiber optics are not affected by electromagnetic interference.

Conclusion

The option that represents a disadvantage for using fiber optic cable is high attenuation. While fiber optics offer many benefits, such as immunity to EMI and high-speed transmission, they can experience signal loss over distance.
