The core advantage of Corning Toneable Cable (detectable/metal-shielded fiber optic cable) lies in its combination of high-speed fiber optic transmission and the positioning capabilities of a metal conductor. Designed for direct burial, it achieves precise underground positioning (toneability) after burial through an external conductive metal layer, effectively preventing damage from accidental excavation during construction. It also boasts high anti-interference capabilities, low loss, and excellent mechanical protection.
Specific advantages include:
Easy underground tracking and positioning: Corning Toneable cables have built-in metal detection lines or sheaths. When used with a conventional metal detector, the location of the underground fiber optic cable can be accurately located, greatly reducing the risk of cable breakage due to excavation.
