Overview of Dielectric Gel-Filled Flat Drop Cable
The Dielectric Gel-Filled Flat Drop Cable is engineered for versatile FTTx applications, including self-supporting aerial, duct, and direct-buried installations. This fully dielectric cable eliminates bonding or grounding requirements while ensuring robust mechanical protection and superior moisture resistance. A single PBT loose tube filled with water-blocking gel houses 1–12 fibers, delivering long-term reliability and easy handling.
Manufactured with a durable HDPE jacket and parallel dielectric strength members, this flat drop cable offers excellent crush resistance, UV protection, and environmental durability for FTTH deployments.
