Underground Direct Burial Flame-retardant Cable GYFTZA53

GYTZA53 6-288 Cores Stranded loose tube fiber optic cable for Direct Burial – Fire Retardant, Armored, UV and Moisture Resistant

This high-performance Outdoor Fiber Optic Cable is engineered for long-term durability in harsh environmental conditions. Designed with a stranded loose tube structure and gel-filled buffer tubes, the GYTZA53 series ensures superior protection for each individual optical fiber against moisture ingress, mechanical stress, and temperature fluctuations. The double-layered armor provides exceptional resistance to rodents, crushing forces, and physical damage—making it ideal for direct burial installations across diverse terrains.

Constructed from low-smoke zero-halogen (LSZH) materials, this fire-retardant cable minimizes toxic emissions during combustion, ensuring safer operation in confined spaces such as data centers, telecom rooms, or underground conduits. Its outer jacket offers excellent resistance to ultraviolet radiation, water penetration, and chemical exposure—critical attributes for both urban and rural deployment scenarios where cables face prolonged sun exposure or soil acidity.

Key features include a robust dual-armored design that enhances tensile strength and crush resistance; a flexible yet durable structure suitable for aerial, duct, and direct burial applications; and an optimized fiber count ranging from 4 to 288 cores, enabling scalable network solutions for metropolitan area networks (MAN), access networks, and backbone infrastructure. Each fiber is individually protected within a free-standing loose tube filled with water-blocking gel, preventing microbending losses and maintaining signal integrity over extended distances.

Engineered for reliability, this fiber-optic solution supports high-bandwidth communication needs including FTTH (Fiber to the Home), mobile backhaul, and enterprise-grade LAN/WAN deployments. Whether installed underground via trenching, pulled through ducts, or suspended along poles, the GYTZA53 cable delivers consistent performance under extreme conditions—from freezing winters to scorching summers—without compromising on safety or efficiency.

Commonly used in telecommunications, utility providers, government infrastructure projects, and private enterprise networks, this cable meets international standards for fire safety, mechanical endurance, and environmental resilience. It’s especially suited for regions requiring compliance with European RoHS, CE, and IEC certifications, offering peace of mind for installers and end-users alike.

Customers consistently praise its ease of installation, long service life, and ability to maintain low attenuation levels even after years of continuous use. Many report improved network uptime and reduced maintenance costs compared to traditional cable types, particularly in areas prone to rodent infestation or heavy traffic loads.

What makes this cable stand out? Unlike generic alternatives, it combines advanced materials science with rigorous testing protocols to deliver unmatched performance in real-world environments. From coastal zones to industrial sites, it remains a trusted choice for engineers seeking a future-proof fiber solution that balances cost-effectiveness with uncompromised quality.

FAQs:

Is this cable suitable for underground installation? Yes, it's specifically designed for direct burial with enhanced armor and waterproofing to withstand soil pressure, moisture, and chemical exposure.

Can it be used indoors as well? While primarily intended for outdoor use, some configurations are compatible with indoor environments like server rooms or telecom closets when proper fire safety regulations are followed.

Does it meet international fire safety standards? Absolutely—it uses LSZH materials that produce minimal smoke and no halogen gases when burned, aligning with global building codes for public infrastructure.

How many fibers does it support? Available in core counts from 4 up to 288, allowing flexibility for small-scale setups or large-scale backbone networks.

Is it resistant to rodents and pests? Yes, the double-armored construction significantly reduces vulnerability to chewing damage from rats and other burrowing animals.

What kind of environments benefit most from this cable? Urban and rural telecommunication networks, industrial facilities, transportation corridors, and any location requiring reliable, long-lasting fiber connectivity with minimal maintenance.
