Dielectric ROC Drop Cable Overview
The Dielectric ROC Drop Cable is a high-performance outdoor flat fiber optic cable specifically engineered for FTTH (Fiber to the Home) deployments. This dry-type, gel-free cable features a fully dielectric structure, making it an ideal solution for aerial, duct, and direct-buried installations without requiring bonding or grounding. Its compact form factor, rugged design, and excellent mechanical properties ensure efficient and long-lasting performance in harsh environments.
Dielectric ROC Drop Cable with FastAccess Technology is a user-friendly fiber optic drop cable designed to save time and labor. Thanks to the advanced FastAccess jacket design, technicians can access the fiber up to 55% faster compared to traditional flat drop cables-no special tools required.
This compact, all-dielectric cable is ideal for FTTH installations, offering easy handling, less slack storage, and lower shipping costs. It supports both field and factory terminations, and requires no bonding or grounding. Available in pre-connectorized assemblies, the ROC Drop Cable helps simplify installation and reduce total deployment time.
