Armored Loose Tube Double Jacket/Single Armor fiber optic cables are designed to provide high fiber counts with the flexibility and versatility required for today's most demanding installations, including direct buried. With fiber counts up to 288 and S-Z strand designs.
The fibers, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath is applied. After the corrugated steel tape is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.

Features for Armored Outdoor Rated Fiber Optic Cable
• Excellent mechanical and temperature performance.
• Special tube filling compound ensure a critical protection of fiber and resist the water.
• Single steel wire as the central strength member to withstand axial loads.
• Inner sheath effectively lower the external mechanical loading.
• Corrugated steel tape longitudinal cover cable core and provide good crush resistance.
• PE sheath protects cable from ultraviolet radiation.
• 100% core filling water prevent cable jelly to ensure the cable watertight.
Application
• Direct buried
• Underground conduit/duct
• Backbone

Service & Support
Comprehensive Warranty & Project-Specific Solutions
We stand behind the strength and performance of our armored loose tube cables. We know these cables are often used for important networks. Because of this, we offer extra help. This includes specific planning advice for your project. We also provide full customization. You can choose the fiber type and count, like single-mode G.652D/G.657, multimode, or a mix. You can select the armor type and the jacket specification. We can also put connectors on the ends at our factory. This saves a lot of work on site.
Technical Expertise for Demanding Deployments
Our technical support is made for difficult outdoor projects. We give clear instructions for grounding the cable, pulling it, and burying it. We can help you calculate the signal loss for long-distance runs. We also guide you on how to handle cable reels. We can give you a full set of documents. This includes test reports for strength and weather resistance. We also provide 3D CAD models to help plan duct routes.
Supply Chain & Logistics for Major Projects
We are ready to support large projects that need many kilometers of cable. This is common for telecom main lines or utility networks. We offer good prices for big orders. We give reliable delivery times, even for custom cables. We ship the cable on strong wooden reels to keep it safe. Our logistics team can work with your build schedule directly.
