72 Core Direct Burial Fiber Cable
GYTY53 direct burial optical fiber cable, Optical fibers are housed in loose tubes that made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a central strength member to form a cable core. The core is protected with water blocking tape ,a layer of inner PE sheath and corrugated steel tape. Then another layer outer PE sheath is extruded.

Tips
Fifteen years of dedication to building optical cables, safeguarding communication for every kilometer.
We've been manufacturing fiber optic cables for a full 15 years!
We're not just a trading company; we're a legitimate manufacturing plant.
Many projects fear fiber optic cables failing after a period of use, leading to significant delays and losses.
With 15 years of accumulated expertise, every batch of our cables undergoes rigorous testing before leaving the factory.
Our cables offer stable transmission, are durable and robust, and are suitable for various indoor and outdoor applications.
We support customization, accepting orders of all sizes. We source directly from the manufacturer, ensuring timely delivery.
Leveraging our 15 years of experience in optical cable manufacturing, we have optimized the structure and process of our underground optical cables for complex direct burial conditions. Employing an armored, reinforced protective design, it boasts excellent resistance to pressure, lateral pressure, and rodent bites, protecting against rock crushing and damage from construction forces.
It features a built-in, complete water-blocking structure, coupled with a corrosion-resistant polyethylene outer sheath, effectively resisting groundwater infiltration and soil acid/alkali corrosion, eliminating signal attenuation caused by water seepage. The optical fiber has low loss, stable transmission, and excellent tensile strength, meeting the requirements of excavation and backfilling construction.
Directly buried underground, it eliminates the need for poles and overhead lines, minimizing the impact of natural weather conditions such as wind, rain, and snow. The concealed and safe wiring reduces the risk of human-caused damage. It is widely used in underground projects such as road infrastructure, security monitoring, rural communications, and cross-regional networking in industrial parks.
Fully tested throughout the entire process before leaving the factory, it supports customization with different core counts, and is supplied directly from the source factory, ensuring the long-term stability of underground communication links.
