Description:
GYFTY53 cable is double sheathed glass yarn fiber cable. The function of using glass yarn is to prevent rodent. The layer stranded loose tubes with water blocking filling compound form a cable core.
Then the inner jacket and outer jacket with material of Polyethylene between glass yarn. The structure of GYFTY53 is suitable for direct buried and duct installation.
Features:
Full cross-section water-blocking structure to ensure good water blocking and moisture resistance.
Loose tube is filled with special ointment for key protection of fiber.
Glass yarn to ensure the the cable has good tensile properties, and rat-bite prevention.
Non-metallic strength member is applicable for multi-thunder area.
Product life is 30 years.
Application:
Core Network, Metropolitan Area Network, and Access Network Outdoor Optical Cable
Laying method: overhead, pipeline
Working temperature: -40℃~+60℃
Bend radius: Static 12.5 times the cable diameter
Dynamic 25 times optical cable diameter
