• Excellent mechanical performance and temperature characteristics
• The loose tube material itself has good hydrolysis resistance and high strength
• The tubes are filled with special jelly compound, providing critical protection for the fibers
• A specially designed compact cable structure effectively prevents tube retraction
• Good crush resistance and flexibility
• The special jacket offers excellent flame retardancy
• The following measures are taken to ensure the water-blocking performance of the cable:
- Single steel wire central strength member
- Special water-blocking compound is filled into the loose tubes
- Fully filled cable core
- Double-sided coated steel tape (PSP) improves the moisture resistance of the cable
