What are two advantages of using fiber optic cabling over traditional copper cables?

1. Immunity to electromagnetic interference

2. Greater cable distances without a repeater

3. More affordable installation cost

4. Increased bandwidth limitations

The correct answer is: Immunity to electromagnetic interference

Immunity to electromagnetic interference is a significant advantage of fiber optic cabling over traditional copper cables. Fiber optic cables transmit data as light rather than electrical signals, which makes them inherently resistant to electromagnetic interference (EMI). This characteristic is particularly important in environments with high levels of electromagnetic noise, as it ensures that the data integrity is maintained without degradation from outside sources. This feature not only enhances performance but also ensures more reliable communication over longer distances. The other advantages of fiber optics, such as greater cable distances without a repeater, also highlight the superiority of fiber optics in specific situations. While the cost is generally higher for fiber optic installations due to the materials and techniques required, the long-term benefits in terms of performance and maintenance often outweigh these initial costs. Additionally, the limitations on bandwidth for copper cables can hinder performance in high-demand applications, while fiber optics offer significantly higher bandwidth capabilities.
