Product Overview
The Toneable Dry Type Flat Drop Cable is designed for FTTH last-mile networks where underground installation and future maintenance require easy cable identification.
It combines a fully dielectric flat drop cable structure with an integrated 24 AWG copper tone wire, allowing technicians to locate buried fiber routes quickly and accurately using standard tone tracing equipment.
With dry water-blocking technology and a robust flat design, this cable ensures fast installation, reduced maintenance cost, and improved operational efficiency for underground fiber networks.
