Overview of Dielectric Dry Core Flat Drop Cable
The Dielectric Dry Core Flat Drop Cable by Unigreat is engineered for self-supporting, direct-buried, and duct installations. Its fully dielectric construction ensures safe and reliable FTTx drop deployment. The single PP loose tube offers excellent mechanical strength under crush and impact conditions, and dry water-blocking technology allows clean, fast, and cost-effective cable preparation. Two parallel dielectric strength members provide superior crush resistance without the need for bonding or grounding.
