Optical Fiber Cable (GYTA33) Gel-filled, Double jacket, Steel wire armored
Video
Structure
Outdoor optical fiber cable for communication with metal strengthening member, loose tube layer twisted filling type, aluminum-polyethylene bonded sheath, single-layer thin round steel wire armored polyethylene outer sheath.
Application
Application range: long-distance communication and inter-office communication
Laying method: direct burial, underwater
Working temperature: -40～+70℃
Bending radius: static 15 times the cable diameter, dynamic 30 times the cable diameter
Features
1. Full-section water-blocking structure to ensure good water-blocking and moisture-proof performance
2. The loose tube is filled with special ointment for critical protection of the optical fiber
3. Phosphated steel wire central reinforcement member has high modulus and corrosion resistance
4. Longitudinal wrapping double-sided film-coated wrinkled aluminum tape, thin round steel wire wrapping and armoring, to ensure the mechanical compression, tensile and ballistic performance of the optical cable, and meet the application requirements of climbing direct burial and underwater laying.
5. The service life of the product is more than 30 years
