Figure 8 self-supporting 24 cores GYTC8S cable is a cutting-edge solution designed for reliable and efficient fiber optic communication, especially in aerial installations. This cable combines robust mechanical properties with excellent fiber protection, ensuring superior performance even in harsh outdoor environments.
The figure 8 aerial cable is engineered to support fiber optic networks in outdoor environments without the need for additional supporting infrastructure like poles or ducts. This self-supporting design is particularly beneficial for reducing installation costs and complexity, especially in locations where conventional underground cabling is difficult or expensive to implement.
The 24-core GYTC8S figure 8 cable consists of both singlemode and multimode fibers, which are arranged in loose tubes. These tubes are then stranded together around a metallic central strength member, creating a compact, circular core that offers high strength and protection. The water-blocking material is carefully integrated into the core to prevent moisture ingress, ensuring long-term durability and performance. The core is then wrapped in a PE sheath, and stranded wires are added as the supporting element, giving the cable its characteristic figure 8 shape.
Key Characteristics:
Excellent Mechanical and Temperature Performance: The cable is designed to withstand harsh environmental conditions, offering reliable performance even in extreme temperatures.
Critical Fiber Protection: The design ensures that the optical fibers are protected from mechanical damage, moisture, and other external factors.
Water Blocking Technology: The cable features advanced water-blocking measures, including a special filling compound in the loose tubes and a steel wire central strength member.
Fiber Optical Specifications:
The GYTC8S figure 8 fiber optic cable uses high-quality G.652D optical fibers, which are widely recognized for their low attenuation and high-performance characteristics, particularly in long-distance transmission.

The GYTC8S figure 8 self-supporting cable is primarily used in aerial installations, where its self-supporting design eliminates the need for additional support structures such as poles or ducts. This makes it ideal for outdoor fiber optic networks, including:
Telecommunication Networks: The cable provides reliable data transmission for telecommunications providers, offering a cost-effective solution for rural and hard-to-reach areas.
Broadband Internet Connections: It is commonly used for delivering high-speed internet to residential and commercial areas, especially in regions where underground cabling is not feasible.
Smart City Infrastructure: The self-supporting feature is especially useful for smart city projects, where fiber optics are essential for connecting various sensors, cameras, and data systems across urban areas.
In addition to its outdoor use, the cable can be applied in any scenario where high-performance, durable fiber optic solutions are required.
To ensure the safe and efficient transport of the GYTC8S, it is carefully packed and coiled on Bakelite and wooden drums. Each reel contains a length of 4000 meters ±2%, and the following precautions are taken during transportation:
The cables must be handled with the right tools to avoid damage.
Protection against moisture, excessive heat, fire sparks, and mechanical stress is essential.
Careful handling is required to avoid overbending or crushing the cable.
Proper packaging and handling ensure that the cable reaches its destination in optimal condition for installation.
