Introduction to Armored Fiber Optic Cable
                     Introduction to Armored Fiber 
Optic Cable?
Introduction: 
● Fiber optic cables can send information over distances as large as 
metropolitan areas. Expense is one of the reasons for fiber optic cables not 
being widely used. Another reason is that fiber optic cables are fragile to 
environmental effects.
Even with protective cladding, fiber optic cables are not safe from:
● water penetration
● rodents attacks
● cracking due to excessive force
Structure of an Armored Fiber Optic Cable:
The above image shows the different layers of an armored fiber optic cable. A 
spiral steel ring outside a conventional fiber optic cable with an extra PVC 
protective layer on top. The yellow fibers are aramid yarn that is a fire retardant 
and blocks water from entering the fibers. Some manufacturers include 
specialized waterproof gel between the inner PVC protective layer and fibers. 
Types of Armored Fiber Optic Cable
Depending on the type of protective winding around the fiber optic cable, the 
armored fiber optic cable is available in two types:
● Interlocking
● Corrugated
Interlocking
Interlocking armored fiber cable has a protective sheath wrapped around the core 
in a spiral shape. It provides crush protection when laid in tight ducts or around 
heavy machinery.
Corrugated
Corrugated armored fiber cable uses corrugated metal tape folded around the 
core. The ridges of the tape discourage rodents from chewing on the cable. 
Hence, this cable type is ideal in areas with high rodent activity and in-between 
walls.
