Unitube Armored Fiber Optic Cable

Single-tube armored optical cable is a type of optical cable that integrates optical fiber and a metal armor protective layer into a compact structure. Its design feature is that the stainless steel tube serves both as the sheath housing the optical fiber and as the direct armor protective layer.

Cable Structure

Optical Fiber: One or more bare optical fibers (typically up to 12 or 24 cores) are placed directly in the core position.

Water-blocking Grout: The optical fiber is immersed in a thixotropic water-blocking grout, whose main function is to prevent moisture from flowing longitudinally within the cable and to provide cushioning.

Armor/Protective Tube (Core Layer): This is a flexible threaded tube made of stainless steel or copper, typically Φ2.0mm or Φ1.6mm. This is the heart of the entire optical cable.

Outer Sheath: A layer of flame-retardant LSZH material or PVC/polyethylene is extruded onto the metal conduit. This sheath provides insulation, corrosion resistance, abrasion resistance, and flame retardant protection, and makes the fiber optic cable easier to handle and lay.

Application

Data Center Internal Connections: Used for high-density connections between server racks and server clusters, requiring resistance to bending and being stepped on.

Building Internal Vertical Shafts and Horizontal Cabling: Particularly suitable for renovations of older buildings, it can be laid directly in ventilation ducts, ceilings, and other areas with high rodent risk.

Industrial Automation and Control Systems: In factory workshops, it needs to withstand oil stains, vibration, and mechanical shock.

Security and Video Surveillance Systems: Used to connect cameras, providing robust protection.

FTTx (Fiber to the Home) Drop Cable: As the final "drop cable" from the junction box to the user's home, it needs to be able to withstand pulling and compression.
