Which of the following is an advantage of using fiber optic cable in the EA-18G?

• A. Increased weight and size
• B. Immunity to electrical noise
• C. Prone to electrical interference
• D. Higher maintenance cost

Answer: (B)

Fibers carry information as light instead of electric current, so there’s no electrical signal traveling through the cable. That means the path is immune to electromagnetic noise from nearby avionics, power systems, and radar-related gear, which is exactly what you want in the EA-18G’s crowded, high-EW environment.

In the Growler, this capability preserves signal integrity and allows high-bandwidth data links and sensor data to flow reliably without interference, all while staying lightweight and compact—benefits that support performance and mission reliability.

That’s why this option is the best fit. Increased weight and size isn’t accurate, since fiber optics are typically lighter and smaller. They aren’t prone to electrical interference, and maintenance costs aren’t inherently higher and can often be lower due to fewer conductive paths and corrosion issues.
