GYTA53 Direct Burial Double Jacket Double Armored Fiber Optic Cable – High-Performance Solution for Underground Communication Infrastructure This robust and reliable fiber optic cable is engineered specifically for direct burial applications, offering exceptional durability and protection against harsh environmental conditions. Designed with a dual-layer polyethylene (PE) outer jacket and double steel armor, the GYTA53 ensures superior mechanical strength, moisture resistance, and long-term performance in challenging underground environments. Whether deploying in urban infrastructure, rural telecom networks, or industrial settings, this cable delivers consistent signal integrity across diverse fiber counts—from 4 to 144 cores—making it an ideal choice for modern data transmission needs. Key Features: The GYTA53 features a centralized steel wire strength member that provides tensile support during installation and long-term stability under soil pressure. Its
loose tube design houses multiple fibers (up to 12 per tube), each filled with jelly compound to prevent water ingress—a critical feature for subterranean installations. The inclusion of a rip cord facilitates easy jacket removal without damaging internal components. Additionally, the use of aluminum and steel tapes adds extra shielding against electromagnetic interference, ensuring optimal signal quality even in electrically noisy areas. Detailed Construction: Each cable segment follows a precise structure: starting from the innermost layer, individual optical fibers are housed within gel-filled loose tubes, which are then surrounded by a central strength member made of high-tensile steel wires. A dual-armored layer composed of corrugated steel tape and aluminum foil offers enhanced crush resistance and rodent protection. Finally, two layers of UV-resistant PE jacketing provide excellent abrasion resistance and chemical stability, enabling deployment in soils ranging from sandy to clay-rich substrates. The overall diameter varies between 11.5 mm and 13.8 mm depending on fiber count, while weight ranges from 140 g/m to 180 g/m—ideal for efficient handling and trenching operations. Applications: Ideal for underground fiber deployments in telecommunications backbones, metropolitan area networks (MANs), FTTH (Fiber to the Home) projects, and enterprise data center interconnects. It supports multi-core wiring systems where reliability and future scalability are essential. This cable excels in both short-haul and long-distance links, especially in regions requiring ruggedized solutions for
outdoor fiber distribution. Commonly used in utility corridors, highway installations, and remote site connectivity, it meets international standards such as ITU-T G.652.D for single-mode fiber compatibility and IEC 60794-1-2 for mechanical and environmental performance. User Feedback: Customers praise its ease of installation, particularly due to the ripcord and flexible yet strong construction. Many highlight its resilience in extreme weather conditions—including freezing temperatures and heavy rainfall—and note minimal signal loss over extended distances. Users in Europe, North America, and Southeast Asia have reported high satisfaction rates when using this cable for municipal broadband expansion and industrial communication upgrades. Frequently Asked Questions: What makes the GYTA53 suitable for direct burial? Its dual-jacketed design and double armor protect against soil stress, moisture, rodents, and temperature fluctuations, making it highly resistant to degradation over time. How does the loose tube structure benefit fiber performance? It allows independent movement of fibers inside the tube, reducing microbending losses and protecting against tension-induced strain during installation. Is it compatible with existing fiber management systems? Yes, the standardized dimensions and color-coded fiber identification make integration into patch panels, splice enclosures, and rack-mounted equipment seamless. Can it be installed in wet or humid environments? Absolutely—the jelly filling and waterproof jackets ensure complete moisture exclusion, preventing corrosion and maintaining low attenuation levels even in saturated ground conditions.
