Armored cable design protects against rodent damage and what else?

• A. Crush
• B. Water intrusion
• C. UV exposure
• D. Temperature changes

Answer: (A)

Armored cable is built with a tough outer layer that adds mechanical strength to protect the fiber inside. That armor makes the cable resistant to external crushing and compression, so it can endure being buried, run through cramped spaces, or placed under equipment without the fibers being crushed. Rodents are deterred by the hard exterior, and the same feature that deters them also shields the cable from crushing forces, which is why crush resistance is the best match for what else armoring provides. Water intrusion protection relies more on the jacket material, seals, and moisture-barrier components rather than the armor itself. UV exposure protection comes from the jacket’s UV-resistant properties, not the armor. Temperature changes affect materials through expansion and contraction, a behavior managed by the chosen jacket and dielectric materials, not primarily by the armor.
