Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a non-metallic central strength member andsurrounded with dry water-blocking material to form a cable core. An extremely thin outer PE sheath is extruded outside the core.
Characteristcs:
1. Good mechanical and temperature performance
2. The following measures are taken to ensure the cable watertight:
3. Single Fiber Reinforced Plastic as the central strength member
4. 100% cable core filling
5. special tube filling compound ensure a critical protection of fiber
6. Crush resistance and flexibility
7. High strength loose tube that is hydrolysis resistant
8. Loose tube filling compound
Properties:
1. Loose tube filling compound ensure good moisture resistance performance
2. Non-mental design can prevent the cable from radio interference and magnetic wave interference
3. High dense fiber packed,small diameter and light weight; it`s the better option for blowing installation progress.
4. Specially designed compact structure is good at preventing loose tubes from shrinking
5. Good flexibility
