Product Description
Product Overview
The GYTA53 4-core direct buried fiber optic cable features a robust construction designed for underground installation in telecommunications networks. With 250µm fibers housed in high-modulus plastic loose tubes and comprehensive water-blocking protection, this cable delivers reliable performance in demanding environmental conditions.
Construction Features
Fibers are positioned in hydrolysis-resistant loose tubes filled with water-resistant compound. A central steel wire provides mechanical strength, while tubes and fillers are stranded around this core. The cable features an Aluminum Polyethylene Laminate (APL) moisture barrier, PE inner sheath, PSP moisture protection, and PE outer sheath for complete environmental protection.
Key Performance Features
- Excellent mechanical and temperature performance (-40°C to +70°C)
- High strength hydrolysis-resistant loose tube construction
- Special tube filling compound for critical fiber protection
- Superior crush resistance and flexibility
- Comprehensive watertight protection with 100% cable core filling
- Steel wire central strength member for mechanical durability
- APL moisture barrier and PSP enhanced moisture-proofing
