The GYDTA optical fiber cable is constructed by sheathing 4, 6, 8, or 12-fiber ribbons within loose tubes fabricated from high-modulus material. These loose tubes are filled with a water-blocking compound. A metallic central strength member forms the core of the cable. The structure of GYDTA optical cable involves placing fiber ribbons in a loose tube with filling gel (the fiber ribbon can be 4, 6, 8, or 12 cores); the central core of the cable is a steel wire (may be added with PE cushioning layer), surrounded by a loose tube and filled with filling rope; the. Loose-layer twisted fiber optical cable GYDTA (72-576 core) is a type of fiber optic cable that is commonly used in communication networks due to its high capacity and long-distance transmission capabilities. It is designed with multiple layers of strength members, loose tubes, and an outer. According to their design, ribbon optical cables are intended to have a large number of optical fibers transferred in a small volume, organized, and most efficiently. Utilizing a stranded loose tube ribbon configuration, these cables integrate multiple fiber ribbons inside durable PBT. features: Non- metallic (FRP)/ Metallic (phosphate steel wire) central strength member, double plastic-coated corrugated steel tape- PE laminated outer sheath.
