All-dry cable

ZTT all-dry fiber cables are designed for fast, clean installation while maximizing duct space efficiency. Their gel-free construction eliminates messy cleanup, enabling simpler splicing and maintenance. With superior tensile strength and bend resistance, these cables optimize pipeline resources while ensuring long-term reliability in diverse environments.

Product Description

ZTT all-dry optical cables feature advanced single-mode or multimode fibers housed in high-modulus PBT micro-loose tubes. Unlike traditional designs, these tubes incorporate innovative dry water-blocking technology using superabsorbent polymers (SAP) instead of messy gels. A central non-metallic FRP strength member provides robust reinforcement, around which the tubes (and optional filler rods) are precisely stranded to form an optimized circular cable core.
The cable employs multiple layers of high-performance dry water-blocking materials: SAP-coated yarns for longitudinal water resistance, water-blocking tapes between core and sheath, optional armored protection (corrugated steel or non-metallic aramid).
The final outer sheath utilizes specially formulated polyethylene (PE) or LSZH material, offering: ultra-smooth surface for reduced friction during installation, excellent resistance to abrasion, chemicals and UV radiation, environmentally friendly composition.

Product Advantages

ZTT All-Dry Optical Fiber Cable delivers an innovative, environmentally responsible solution for modern communication networks, combining installation efficiency with long-term performance reliability.
The completely gel-free design of all-dry optical cables eliminates messy grease entirely, removing the need for tedious cleaning during installation.
Manufactured with recyclable materials, compliant with RoHS standards, it reduces carbon footprint throughout product lifecycle.
