A-DQ(ZN)B2YUCFIBRE O CT D DA PE 3.0kNLWL outdoor cables with central loose tube serve as underground and tube cables and are used in the primary area (campus backbone), where a fiber count of up to 24 is required. The compact loose tube design allows a high concentration of fibers and thus facilitates fiber management in the distribution systems. The cable is UV-resistant, metal-free, rodent-proof, longitudinally watertight, tensile-resistant and suitable for direct burial.
