What is an advantage of using fiber optics in communication?

The advantage of using fiber optics in communication primarily lies in their immunity to electromagnetic interference. This is a significant benefit because fiber optic cables transmit data as light signals rather than electrical signals. Consequently, they are less susceptible to noise and interference from external sources such as radio frequency interference (RFI) and electromagnetic interference (EMI), which can affect traditional copper cables. This characteristic allows for more reliable communication, particularly in environments with high electronic activity or where signal integrity is paramount.

In scenarios where high-speed data transmission is required, this immunity ensures the fidelity and clarity of the transmitted signals, resulting in higher data rates and longer transmission distances without degradation of quality. This makes fiber optics an ideal choice for networks that are sensitive to interference and require consistent performance, such as in data centers, hospitals, and industrial settings.

While other options may present some benefits, the unique characteristic of fiber optics' immunity to electromagnetic interference stands out as a primary advantage in ensuring effective and stable communication.
