Stranded Loose-Tube Armored Optical Cable

Product Overview

Stranded loose-tube armored optical cable (e.g. GYTY53) uses high-strength hydrolysis-resistant loose tubes filled with special jelly for critical fiber protection. It offers good mechanical performance, temperature characteristics, crush resistance, and flexibility for direct-buried and duct environments that need higher mechanical protection. Stable and reliable for telecom network build-out and O&M.

Construction:
Stranded loose-tube
Protection:
Standard armor
Fiber Protection:
Special jelly in tubes
Features:
Excellent mechanical and temperature performance
