Material: high modulus plastic
Tubes are filled with a water-resistant filling compound
Tubes (and fillers) are stranded around the strength member into a compact and circular core
Cable core is covered with a thin polyethylene (PE) inner sheath, is filled with jelly to protect it from water ingress
A layer of water-blocking material is applied around the cable core to prevent water ingress all the same
After a corrugated steel tape armor is applied, cable is completed with a PE outer sheath
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Crush resistance and flexibility
PE sheath protects cable from ultraviolet radiation

Following measures are taken to ensure the cable watertight:

• Single fiber reinforced plastic as the central strength member
• Loose tube filling compound
• 100% cable core filling
• PSP enhancing moisture-proof
• Water-blocking material
