Colored optical fibers are placed into loose tubes made of high-modulus materials, and the loose tubes are filled with thixotropic water-blocking fiber paste.
At the center of the cable core is a metal strength member. The loose tubes (and filler ropes) are stranded around the central strength member to form a circular cable core. The gaps in the cable core and the space between the cable core and the aluminum tape are filled with water- blocking cable paste. After the plastic-coated aluminum tape is longitudinally wrapped, a polyethylene sheath is extruded.

Note: The dimensions and performance values of the product can be customized according to customer-specific requirements.
- The loose tube material itself has good hydrolysis resistance and high strength.
The tube is filled with special grease, which provides key sealing protection for the optical fibers.
The PE sheath has excellent UV radiation resistance.
The single steel wire central strength member helps with the alignment and tensile resistance of the optical cable.
It has excellent mechanical properties and temperature characteristics.
The double-sided corrugated steel tape (PSP) enhances the cable's moisture resistance, and the corrugated part combines better with PE, making the structure more robust.
- High-quality water-blocking materials prevent longitudinal water seepage of the optical cable.
