The Hexatronic slim duct cable series combines state of the art installation performance, ultra-low attenuation and a high mechanical and environmental performance.

The cable type is typically used in transport applications such as terrestrial long-haul or metro networks where low attenuation and cable performance are prime concerns.

With a reduced outside cable diameter and optimised cable stiffness, the cables can be air-blown or water-jetted long distances without the need for splicing. A reduced cable diameter also allows for reduced duct diameters which will simplify and reduce the cost of material handling in field.

Thanks to the central strength member design and a robust sheath the cables can also be installed by traditional pulling techniques.

The cables are based on a dry concentric core, slim loose tube design with up to 16 tubes per cable. The cables have one or two layers of inner protective tubes made of a robust PBT compound where each tube has 12 fibers.

The design facilitates easy fibre preparation and mid-span access.
