Fiber optic cable is not subject to the same distance limits as copper.

• A. True
• B. False
• C. Not subject to the same distance limits as copper
• D. Only at high speeds

Answer: (C)

Signal transmission distance depends on how the medium handles loss and interference. Fiber optic cable carries light, which experiences far less attenuation over distance and is not affected by electrical noise in the environment. That means you can send data over much longer runs with fiber than with copper at the same speeds, and you can achieve even higher speeds over long distances with the right fiber type and components. So, fiber isn’t subject to the same distance limits as copper—the practical link lengths are typically much longer. Of course, there are still limits set by optical loss and dispersion, but those are different constraints than the attenuation and EMI limits that cap copper. This is why the statement is considered correct.
