Overview of Toneable Dry Core Flat Drop Cable
The Toneable Dry Core Flat Drop Cable is engineered for aerial, duct, and direct-buried FTTH applications. Featuring a single loose tube with 1–12 fibers and parallel dielectric strength members, this cable delivers superior mechanical protection, crush resistance, and easy installation. Its dry water-blocking technology enables faster, cleaner cable preparation without the need for bonding or grounding.
Built with a durable HDPE jacket, the cable resists UV, abrasion, and environmental factors. The embedded copper conductor allows effortless toneable location for direct-buried installations, making it ideal for ISPs, telecom operators, and integrators.
