What level of mechanical protection does the steel wire armour offer?

The corrugated steel wire armour provides high crush resistance, impact withstand, and tensile strength, making the cable suitable for direct burial without additional metallic conduit. It effectively deters rodent attacks and withstands compressive loads encountered in ducted and buried installations. When tested according to IEC 60794-1-2, the armour ensures the optical fibres maintain integrity under severe mechanical stress, safeguarding signal continuity in industrial, campus, and outdoor backbone networks.
