Which of the following statements is true regarding fiber optic cables?

Fiber optic cables are indeed immune to electromagnetic interference, which is one of their significant advantages over traditional copper cables. This immunity comes from the fact that fiber optics transmit data using light rather than electrical signals. Since light signals are not affected by electromagnetic fields, fiber optic cables maintain signal integrity even in environments with high levels of electromagnetic interference. This characteristic makes fiber optics especially suitable for applications in industrial settings or locations with a lot of electronic equipment where interference could lead to data loss or degradation of signal quality.

In contrast, other options present limitations that do not apply to fiber optics. For example, fiber optic cables are generally lighter and less bulky than copper cables, making them easier to install and manage. While fiber optics can be considered more fragile in terms of bending and installation requirements, they also provide greater durability in terms of resistance to environmental factors like moisture and corrosion. Furthermore, fiber optic cables can transmit data in both directions simultaneously (full-duplex communication), contrary to the notion that they operate in only one direction.
