What is an essential feature of armored cables?

Armored cables are specifically designed to provide protection from physical damage, including rodent interference. The armored layer, which is typically made of steel or aluminum, acts as a barrier against various types of mechanical impacts, including those from rodents that might chew on cables. This protective feature is crucial in environments where such threats are prevalent, making armored cables particularly useful in outdoor installations, industrial settings, or anywhere there is a risk of damage from animals or harsh conditions.

While resistance to water, high flexibility, and low attenuation are important characteristics for fiber optics, they are not the primary functions of armored cables. Water resistance can be achieved in other ways, flexibility largely depends on the design and material of the cable itself, and attenuation is a characteristic that relates to signal strength rather than physical protection. The defining feature of armored cables remains their robust design to safeguard against physical threats, underlining the importance of option B.
