GYTA53 Direct Buried Fiber Optic Cable 2-144 Core Double Armored

Product Overview

The GYTA53 cable is specifically engineered for direct buried (underground) installations where high mechanical protection is mandatory. Designed to withstand extreme pressure and rodent attacks, it features a sophisticated Double-Armored and Double-Jacket construction.

At its core, the fibers are housed in high-modulus loose tubes filled with a water-resistant compound. The structure includes an aluminum tape (APL) moisture barrier, an inner PE sheath, and a longitudinal corrugated steel tape (PSP) armor, all encased in a rugged outer PE jacket. This multi-layer defense makes the GYTA53 the "gold standard" for harsh underground environments.

Key Performance Features

• Double Armoring for Maximum Protection: The combination of Aluminum tape (moisture barrier) and Steel tape (mechanical protection) ensures the cable can withstand heavy soil pressure.

• Superior Crush & Rodent Resistance: The corrugated steel tape (PSP) provides a hard physical barrier against rodents and accidental mechanical impact during excavation.

• Excellent Water Blocking: Dual-layer moisture barriers and water-blocking compounds prevent "water-treeing" and protect signal integrity over decades.

• High Tensile Strength: A solid central strength member (FRP or Steel wire) ensures the cable maintains its structural integrity during high-tension pulling.

• Direct Buried Ready: Engineered specifically for underground use without the need for additional conduits or ducting.

Technical Specifications

Common Application Scenarios

The GYTA53 is the backbone of heavy-duty outdoor infrastructure:

• Underground Direct Burial: Primary choice for long-distance communication lines where trenching is used and no duct is available.

• Rodent-Prone Areas: The steel armor is essential for protecting fiber in agricultural or forest zones where cable-gnawing animals are present.

• Harsh Soil Conditions: Suitable for areas with high moisture, acidity, or rocky soil that requires extra chemical and physical resistance.

• Inter-City Backbone Networks: Provides the high-capacity, durable link required for regional telecommunication hubs.

• Industrial & Mining Sites: Reliable data transmission in heavy industrial zones with high mechanical vibrations and soil movement.
