GYTA33 Direct Burial and Underwater Fiber Optic Cable
Product Description
GYTA33 fiber optic cable features a robust structure designed for harsh environments. The 250µm fibers are housed in loose tubes made of high-strength materials, filled with water-blocking gel to protect the fibers. A central metallic strength member provides structural support, and in certain designs, a polyethylene (PE) sheath is extruded over this core. The tubes are helically stranded around the central strength member, with the interstitial spaces filled with water-blocking compounds. An aluminum moisture barrier is applied longitudinally, followed by a PE inner sheath. The cable is armored with a layer of smooth, round steel wires for mechanical protection, and finished with a durable outer polyethylene jacket.
Key Features
-
Full-section water-blocking design provides excellent moisture resistance.
-
Special gel filling inside the tubes offers effective fiber protection.
-
Precision control of fiber excess length ensures stable performance under tension and temperature variations.
-
Steel wire armor enhances tensile strength and resists external pressure.
-
Outer PE jacket is UV- and radiation-resistant for long-term durability.
-
Expected lifespan exceeds 30 years under proper conditions.
Applications
-
Ideal for outdoor network installations.
-
Suitable for direct burial installation.
-
Designed for wet environments, including underwater and shallow submarine use.
