What is a characteristic of fiber optic systems regarding environmental factors?

Fiber optic systems are designed to transmit data using light, making them significantly less affected by environmental factors compared to traditional copper cabling. One of their defining characteristics is their immunity to moisture and temperature changes, which means that fluctuations in humidity and temperature do not impact the performance or integrity of the data transmission.

This immunity arises because fiber optics use glass or plastic fibers to transmit light, which are not susceptible to electrical interference or corrosion that can affect metals and other materials found in conventional cables. Consequently, fiber optic systems can perform reliably in various environmental conditions, making them a preferred choice for long-distance communication and in settings where environmental stability cannot be guaranteed.

The other options suggest various vulnerabilities that fiber optic systems do not possess, reinforcing the fact that their design inherently provides resistance to several environmental challenges.
