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, and the gaps in the cable core are filled with water-blocking cable paste. After the double-sided coated steel tape is longitudinally wrapped, a flame-retardant sheath is extruded to form the cable.

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 special sheath has excellent flame retardancy.
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.
