Armored fiber optic cables are much stronger and tougher than common cables, which are designed to withstand crush, pressure, and rodent issues. They possess high flexibility and durability when used in harsh environments or limited space.

When it comes to unarmored and armored fiber optic cables comparison, the distinctive difference lies in the outer protective layer. Precisely speaking, the armoring material doesn’t have to be metal, which can be fiber yarn, glass yarn, polyethylene, etc. The additional outer protective layer for optical cable makes the armored cable special, so the armored cables will be installed in locations that may expose to mechanical damages, while unarmored cables are normally used for control systems.
