ROC Drop Cable Description
The ROC Drop Cable family includes both Toneable ROC Flat Drop Cable and Dielectric ROC Flat Drop Cable, designed for self-supporting aerial, direct-buried, and duct FTTX drop installations. Compact and easy-to-access, these flat drop cables streamline installation and handling while offering excellent mechanical performance under crush and impact tests.
Dry water-blocking technology ensures clean, fast, and cost-effective preparation. PE single jacket with additives provides durability, UV resistance, fungus resistance, and abrasion protection. Two parallel dielectric strength members give exceptional crush resistance without bonding or grounding.
The Toneable ROC Flat Drop Cable includes a 24 AWG copper conductor for easy detection, while the Dielectric ROC Flat Drop Cable is fully dielectric for metallic-free deployments.
