Integrated steel strand can lower total installation cost by ~30% vs. non‑self‑supporting designs, and workers can fix 3‑4 km per day. | Same integrated messenger design provides similar installation savings, especially on medium to long spans. However, heavier construction (stranded design) may need slightly more labor for splicing and routing. | No built‑in messenger means mandatory separate steel strand or ADSS‑style installation. Adds extra materials, labor, and slower progress. Generally 20‑40% higher installation cost vs. figure‑8 types. |

A: Usually it is 15-20 days from the date of order placement, but it also depends on the quantity of the order. You need to confirm the specific delivery time with the sales manager.
1. What is GYXTC8S fiber optic cable used for?
GYXTC8S is a figure-8 self-supporting aerial fiber optic cable designed for outdoor overhead installations. It is widely used in long-haul communications, metropolitan area networks (MAN), access networks, CATV systems, FTTx deployments, and rural telecom networks.Its integrated messenger wire design allows direct pole-to-pole installation without separate support strands, making it ideal for areas where underground duct infrastructure is unavailable.
2. What is the difference between GYXTC8S and GYTC8S?
Both are figure-8 self-supporting aerial cables, but they differ in structure and fiber capacity. GYXTC8S uses a central loose tube design where all fibers are housed in a single tube, supporting 2 to 24 cores. GYTC8S uses a stranded loose tube design with multiple tubes stranded around a central strength member, supporting up to 144 cores. For small to medium core count projects (up to 24 cores), GYXTC8S is more compact and cost-effective; for high core count trunk lines, GYTC8S is the better choice.
3. How much does GYXTC8S cost?
GYXTC8S pricing typically ranges from US$0.09 to US$0.65 per meter, depending on fiber count and order quantity.In bulk orders, prices can drop significantly. For example, a 12-core single-mode GYXTC8S is priced around US$0.65/m at retail, while high-volume orders (2000m+) can bring prices down to approximately US$0.05–0.10/m.[reference:6] Compared to non-self-supporting cables requiring separate messenger lines, GYXTC8S can reduce total installed cost by eliminating additional hardware and labor.
4. How is GYXTC8S installed?
Installation is straightforward due to its self-supporting design. The steel messenger wire integrated into the figure-8 profile is pulled and clamped to poles, while the fiber cable section hangs below. Key requirements: short-term tensile strength ≤1500N (long-term ≤600N), dynamic bending radius ≥20× cable diameter, static ≥10× cable diameter, and span lengths up to 150 meters.Always pull the steel messenger only, not the fiber section, and use proper suspension clamps (load rating ≥6kN).
5. Is GYXTC8S waterproof and rodent-resistant?
Yes. GYXTC8S features a full cross-section water-blocking structure with water-blocking gel inside the loose tube and water-blocking tape between layers, which passes 1m water column tests for 8 hours without leakage.Additionally, the corrugated steel tape armor (PSP) provides protection against crushing, impact, and rodent attacks, making it suitable for harsh outdoor environments.
6. What is the lifespan of GYXTC8S cable?
The designed service life of GYXTC8S is 25 to 30 years when properly installed.The UV-resistant PE outer sheath ensures good weather resistance and anti-aging properties, while the precision-controlled fiber excess length guarantees stable mechanical and thermal performance throughout its operational life in outdoor aerial conditions.
