144 Core Fiber Optic Cable GYTY53 Outdoor Armored Double Jacket

Overview of 144‑Core GYTY53 Fiber Optic Cable

144‑Core GYTY53 Fiber Optic Cable is a high‑capacity, outdoor armored fiber cable designed for backbone and long‑distance telecommunication networks. This model contains 144 individual optical fibers housed in loose tubes, providing exceptional bandwidth, low attenuation, and strong mechanical performance in harsh environments.

Each fiber is protected within PBT loose tubes filled with water‑blocking gel, stranded around a central strength member, and covered by double layers of PE and corrugated steel tape. The GYTY53 structure ensures superior longitudinal water resistance, crush resistance, and rodent protection—ideal for buried, duct, or direct outdoor installation projects.
