The D-CONNECT Multi Loose Tube Fiber Optic Cable is a high-capacity unarmoured backbone solution supporting 24 to 288 fiber cores. Designed for indoor and protected outdoor installations, it offers gel-filled moisture protection, water-blocking yarns, and flexible customization for telecom and data networks.
The D-CONNECT Multi Loose Tube Fiber Optic Cable is a high-performance unarmoured backbone fiber optic cable developed for telecommunication, enterprise, and data center network infrastructure. Supporting 24 to 288 fiber cores, this cable is ideal for medium to large-scale fiber backbone and distribution networks requiring stable transmission, long service life, and cost-effective deployment.
Available with OS2 single-mode and OM1, OM2, OM3, OM4, and OM5 multimode fibers, it ensures compatibility with modern high-speed network architectures. The gel-filled loose tube construction provides excellent moisture resistance, protecting optical fibers from environmental stress and ensuring long-term reliability.
To further enhance durability, water-blocking glass yarns protect against water ingress, making the cable suitable for duct, conduit, and protected outdoor installations. Its lightweight and compact design allows easy handling, transport, and fast installation, reducing overall deployment time and cost.
Engineered to perform across a wide temperature range, and available with multiple outer jacket materials and color options, the D-CONNECT Multi Loose Tube Unarmoured Fiber Optic Cable delivers the flexibility and performance required for modern broadband networks, telecom backbones, campus networks, and data center interconnections.
The Dconnect Multi Tube Unarmoured Fiber Optic Cable is manufactured in accordance with the highest international quality and performance standards to ensure reliability, safety, and interoperability across a wide range of applications.
