Direct Buried Double Armored Double Jacket Fiber Optic Cable GYFTA53

Direct Buried Double Armored Double Jacket Fiber Optic Cable GYFTA53

FIBERFUTURE® GYFTA53 cable, The loose tubes are made of high modulus plastics (PBT) and filled with water resistant filling gel. Loose tubes are stranded around the FRP central strength member, cable core is filled with cable filling compound. The corrugated aluminum tape folding and polyethylene (PE) is extruded as inner sheath, then water swollen yarns and corrugated steel tape is longitudinally applied over the inner sheath, and combined with a durable PE sheath.

Main Features

Accurate control of fiber excess length and SZ stranded method to ensure that the cable has excellent mechanical and environmental performance.
The material of the loose tube is with excellent hydrolysis resistant performance and high tensile strength, and the tube is filled with special fiber grease in order to provide crucial protection for the fiber.
The structure of double-layer armoring and double-layer sheathing improves the cable’s performance of pressure resistance, bulletproof, moisture resistance, and effectively prevents the cable from rodent bite.
Following methods are adopted to ensure the cable’s excellent water-resistant performance:
1. Single steel wire central reinforcement.
2. The loose tube is filled with special waterproof compounds.
3. Cable core is filled with special grease.
4. Coated APL moisture-resistant layer.
5. Two-side coated PSP moisture-resistant layer.
6. Good water-blocking material to prevent the cable from vertical water penetration.
Maximum fiber number: 288.
