An armored optical cable is a special optical cable with a protective stainless steel armor tube wrapped around the fiber core. The metal armor layer effectively protects the fiber core from animal biting, moisture corrosion and various external damages. This “armor” is typically made of steel, either as a corrugated tube or interlocking strips, wrapped. Unlike standard indoor cables, which rely on simple aramid yarns and a thin LSZH jacket, a heavy duty outdoor optical cables design employs a sophisticated, multi-layered defensive architecture. Armored optical cables are used in applications where the fiber optic cable may be exposed to harsh environments such as extreme temperatures, humidity, moisture, and mechanical stress.
