Why choose Armored Fiber?

Posted by Samantha Bante on Sep 8, 2017 1:00:00 PM

Last month we compared Fiber Optics to traditional Copper Cables and the differences between the two in regards to data transmission. Within the Fiber Optic product line, Armored Fiber Optics is an option for businesses that require installation within rigid environments.

Armored Fiber Optic Cable can be utilized for: telecommunication, high bandwidth data, video signaling, long-distance CCTV, communication between fire alarm panels, and much more.

What is Armored Fiber Optic Cable?

Compared to Unarmored (Figure A), Armored Fiber Optic Cable (Figure B) contains almost all of the same features. The differences between the lie within the construction, intended use and outside factors that could harm the transmission of signal for any business.

Armored Fiber consists of tiny hair-like fibers just like Unarmored Fiber but, the cable is surrounded by an interlocking aluminum armor which is rippled in design (see Figure B), and then covered by an outer jacket. This allows the cable to carry higher bandwidth frequencies and can be used for direct burial installations due to the interlocking aluminum armor surrounding the fiber. 

Armored Fiber Features:

  • Superior Bandwidth
  • Armored Fiber Plenum – allows for plenum pulls and outside direct burial without a transition
  • Pull Tensions
    • Fiber Optics up to 400lbs.
  • Less Signal Degradation
  • Long Distance Installation
  • Easy Installation – Lightweight and Easily Terminated
  • Greater Security (no EMI/RFI)
  • Energy Efficient (Light waves transmitted through glass or plastic threads (fibers) use much less energy than data signals sent through metal conductors.)
  • Easier to Make System Upgrades


Armored Fiber Optic Cable is suitable for both indoor and outdoor applications. Armored Fiber Optic Cables can be installed in high traffic locations where sun and moisture could potentially harm data transmission. 

These cables are also plenum-rated and do not need to be transitioned when pulled indoor when being installed which offers a more cost-effective approach while meeting building and safety codes.
