GYXTC8Y Self-supporting Fig.8 Unitube Fiber Optic Cable

Mini Figure 8 Self-Supporting Fiber Optic Cable – GYXTC8Y (4–24 Core) for Aerial and Underground Deployments

This compact yet robust fiber optic cable is engineered for high-performance outdoor communication networks. The GYXTC8Y figure-8 design combines a central loose tube structure with a galvanized steel messenger strand, enabling reliable aerial installations without additional support wires. Ideal for both urban and rural deployments, this self-supporting solution delivers consistent signal integrity across extreme weather conditions and challenging terrains.

Key features include a gel-filled buffer tube that protects individual optical fibers from moisture, mechanical stress, and temperature fluctuations. Each fiber is encased in a viscoelastic jelly compound, minimizing microbending losses and ensuring long-term durability. Aramid yarn reinforcement adds tensile strength while maintaining flexibility—critical for safe handling during installation and maintenance. The outer polyethylene (PE) jacket offers superior UV resistance, waterproofing, and abrasion protection, making it suitable for direct burial or overhead stringing in harsh environments.

Available in core counts ranging from 4 to 24, the GYXTC8Y cable supports single-mode YOFC fiber types optimized for low attenuation and high bandwidth transmission. Its standardized dimensions—7.0 mm outer diameter, 1.5 mm sheath thickness, and 3 mm steel strand diameter—ensure compatibility with existing infrastructure and splicing tools. Designed for operation between -40°C and +60°C, this cable performs reliably in arctic climates, tropical humidity, and everything in between.

Common applications include FTTH (Fiber to the Home), telecom backhaul links, metropolitan area networks (MANs), and industrial communication systems. Whether installed as a self-supporting Aerial Cable or buried directly in ducts or trenches, the GYXTC8Y provides dependable performance for long-haul and local network segments alike. It’s particularly favored by network engineers seeking a cost-effective, low-maintenance alternative to traditional armored cables.

Users appreciate its ease of termination, minimal bending radius, and excellent crush resistance. Field technicians report reduced downtime due to fewer splice points and improved fault tolerance. Many international clients have adopted this product for smart city projects, rural broadband expansion, and hybrid fiber-coaxial (HFC) upgrades where resilience and scalability are paramount.

Q: Is this cable suitable for underground use? A: Yes, the PE jacket and gel-filled tubes make it ideal for direct burial in soil, concrete conduits, or ducts. Q: What makes the figure-8 design advantageous? A: It allows independent tension distribution between the fiber core and the steel messenger, reducing strain on the optical fibers during installation and thermal expansion. Q: Can I install this cable in high-wind areas? A: Absolutely—the galvanized steel component enhances structural stability, and the lightweight profile minimizes wind load compared to heavier alternatives. Q: Does it meet international standards? A: Yes, it complies with ITU-T G.652.D, IEC 60794-1, and other global telecom specifications for outdoor fiber deployment.
