Uni-tube non-metallic air-blowing micro cable

This is a single-tube, non-metallic, air-blown micro cable. It contains a 250μm single-mode or multi-mode optical fiber housed in a loose tube made of high-modulus material. The tube is filled with non-toxic, waterproof gel. The loose tube is stranded with aramid or other non-metallic reinforcement elements. Finally, a black or colored high-density polyethylene (HDPE) outer sheath is extruded to complete the cable.

Air-blown micro cables are a space-saving installation solution using compressed air to push small-diameter cables through pre-laid micro tubes. This method eliminates complex pulling, reduces labor costs, and allows more fibers per conduit. The cables are protected within tubes, ensuring durability and easy future upgrades. They are widely used in data center interconnections, 5G networks, metropolitan area networks, and challenging environments like bridges or mountainous terrain.

‌Key Features:‌

  • ‌Non-Metallic Design:‌ Effectively prevents radio frequency and electromagnetic interference.

  • ‌Tight Structure:‌ Ensures the sleeve does not shrink.

  • ‌Aramid Reinforcement:‌ Provides excellent tensile strength.

  • ‌Loose Tube Compound:‌ Guarantees superior moisture resistance.

  • ‌Flexible:‌ Offers good flexibility.

  • ‌Dense Packing:‌ Results in small diameter and lightweight construction.

‌Applications:‌
This uni-tube non-metallic air-blowing micro cable is suitable for backbone networks, access networks, and fiber to the home (FTTH).
