Steel Wire Armored Tight Buffer Fiber Optic Cable

This rugged fiber optic cable is built with tight-buffered optical fibers, water-blocking aramid yarn, and a layer of helically wound steel wires between inner and outer sheaths. Its all-terrain durability makes it suitable for industrial, security, and outdoor-to-indoor network applications.

1. Structure & Design

Structure & Design

From inside to outside, the cable is structured as follows:

• Tight Buffered Optical Fibers

• • 900μm tight buffer for easy stripping and direct termination

  • Fiber types: G.652.D, G.657.A1/A2, OM2/OM3/OM4

  • Fiber count: 2 to 48 cores, color-coded

• Water-Blocking Aramid Yarn

  • Surrounds the fiber bundle for tensile strength and moisture resistance

• Rip Cord

  • Placed under the sheath for quick and easy jacket removal during installation

• Inner Sheath

  • Typically LSZH or PE, protects fiber unit and isolates it from armor

• Steel Wire Armor

  • Full-circle steel wires, helically wound for maximum crush resistance, rodent protection, and mechanical durability

• Outer Sheath

  • UV-resistant, flame-retardant LSZH or TPU jacket

  • Custom colors available (black standard)

• Typical Diameter: ~6–13 mm, depending on fiber count

• Operating Temperature: -40°C to +70°C

2. Applications

• Industrial Ethernet and control systems
• Military or field-deployable communication links
• Outdoor-to-indoor cable transitions
• Tunnels, mines, power stations
• Rodent-prone or high-crush-risk environments
• Backbone cable for video surveillance systems (CCTV)

3. Advantages

• Full-circle steel wire armor provides excellent mechanical protection

• Up to 48 cores in tight-buffered form, easy for termination without fan-out kits

• Water-blocking yarn protects against moisture penetration

• Rip cord allows for quick access during installation

• Dual-sheath design enhances environmental resistance

• Flame-retardant, UV-resistant jacket for indoor/outdoor versatility

4. FAQs

• Q1: Can I terminate this cable directly in a patch panel?
  Yes. Thanks to the tight-buffered design, this cable is suitable for direct termination with no need for breakout kits.

  Q2: Is it suitable for environments with rodents?
  Absolutely. The steel wire armor layer provides excellent rodent protection.

  Q3: Is this cable waterproof?
  The water-blocking aramid yarn prevents moisture migration inside the cable, making it suitable for damp or outdoor conditions.

  Q4: Can it be buried directly?
  Yes, with its armored and double-sheathed design, it’s suitable for direct burial or conduit installation.

  Q5: Can you customize the fiber type, sheath material, and color?
  Yes. We offer full customization including fiber type (SM/MM), jacket material (TPU/LSZH), and color coding.
