Product Description
CHANGRONG TECH ™ Outdoor Stranded Loose Tube Double Jacket Underground Direct Buried Fiber Optic Cable 2core-288core Armored Fiber Cable GYTY53/GYFTY53/GYTA53/GYFTA53
Direct Buried Cables are specifically designed for installation in harsh underground environments for outdoor use. It integrates multiple protective layers and a steel tape armor structure to resist external mechanical damage, moisture, corrosion, and soil pressure—making it a ideal solution for long-distance, underground optical communication networks.
Application:
Direct-burial / Duct / Non Self-supporting Aerial Installation
Cable Construction:
Direct Buried Cable type 1: Double Jacket Single Armor (GYTY53, GYFTY53)
Single Armor layer: Corrugated Steel Tape (CST)
Single Armor layer: Corrugated Steel Tape (CST)
Direct Buried Cable type 2: Double Jacket Double Armor (GYTA53, GYFTA53, GYTS53, GYFTS53)
Double Armor layer: Corrugated Steel Tape (CST) and Aluminum Tape (APL)
Double Armor layer: Corrugated Steel Tape (CST) and Aluminum Tape (APL)

CST Armored Direct Buried Fiber Cable GYTY53, GYFTY53
The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the strength member (steel wire or FRP) to form the cable core. Then the cable core is filled with water-blocking compound and covered with a PE inner jacket. After the corrugated steel tape (CST) is longitudinally armored over the inner jacket, the cable is completed with a PE outer jacket.
Features:
Good mechanical and thermal performance
Steel wire or FRP as the central strength member
Hydrolysis resistant loose tube
Tube filling gel ensures critical protection of fiber
Stranded compact structure eliminating contraction of tubes
Rugged, durable PE jacket protects against UV radiation, fungus etc.
Crush resistance and flexibility
Water-blocking measures :
- Loose tube gel-filled
- 100% cable filling compound
- Corrugated steel tape (CST) enhancing moisture-proof

GYTY53 FIBER OPTIC CABLE
GYFTY53 FIBER OPTIC CABLE
APL+CST Double Armored Direct Buried Fiber Cable GYTA53, GYFTA53
The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the strength member (Steel wire or FRP) to form the cable core. An Aluminum tape(APL) is applied around the core, which is filled with the water-blocking compound. Then the cable core is covered with a PE inner jacket. After the corrugated steel tape (CST) is longitudinally armored over the inner jacket, the cable is completed with a PE outer jacket.
Double Armor Key Functions:
- Anti-compression: Withstands heavy loads (e.g., vehicle traffic, soil pressure in deep burial).
- Anti-tension: Enhances tensile strength for long-distance pulling (e.g., horizontal directional drilling).
- Anti-rodent: Steel's rigidity resists severe rodent damage (critical for rural/wooded areas).
- Anti-compression: Withstands heavy loads (e.g., vehicle traffic, soil pressure in deep burial).
- Anti-tension: Enhances tensile strength for long-distance pulling (e.g., horizontal directional drilling).
- Anti-rodent: Steel's rigidity resists severe rodent damage (critical for rural/wooded areas).
Characteristics:
(1) Excellent Mechanical Protection
(2) Superior Environmental Adaptability
(3) Easy Installation & Low Maintenance
- Direct Burial: No need for expensive protective ducts (reduces construction costs and time).
