Colored optical fibers are placed into loose tubes made of high-modulus, hydrolysis-resistant material, and the loose tubes are filled with thixotropic water-blocking paste. At the center of the cable core is a metal strength member, around which the loose tubes (and filler ropes) are stranded to form a compact and circular cable core. The cable core is longitudinally wrapped with a layer of plastic-coated aluminum tape, and then integrated with steel wire strands into an 8-shaped polyethylene sheath.

It has excellent mechanical properties and temperature characteristics.
Steel strands used as self-supporting elements meet the tensile strength required for aerial optical cables, facilitating self-supporting aerial installation and reducing installation costs.
The loose tube material has good hydrolysis resistance and excellent lateral pressure resistance.
The tube is filled with special grease, providing critical protection for the optical fibers.
The double-sided coated steel tape enhances the cable's moisture resistance.
