OYI: Redefining Fiber Optic Infrastructure
Established in 2006 and headquartered in Shenzhen’s technology hub, Oyi international., Ltd. has emerged as a global leader in mission-critical fiber optic solutions. With ISO 9001-certified manufacturing facilities and a 20-member R&D team specializing in material science and network architecture, the company delivers precision-engineered systems to 268 clients across 143 countries. Our portfolio addresses the evolving demands of telecommunications operators, power utilities, and smart city developers. The ASU Self-Supporting Optical Cable Solution, a cornerstone of our innovation, exemplifies OYI’s ability to merge technical sophistication with operational practicality.
ASU Cable System: Technical Specifications and Industry Applications
The ASU Self-Supporting Optical Cable redefines aerial fiber deployment through its hybrid dielectric construction and load-optimized design. Unlike conventional cables requiring separate messenger wires, this all-in-one solution integrates tensile reinforcement within its structure, enabling direct aerial installation across spans up to 1,500 meters. Below, we analyze its engineering principles and field performance.
1. Structural Innovation and Material Science
Core Design: Incorporates FRP (Fiber-Reinforced Plastic) central members with E-glass dielectric yarns, achieving a tensile strength of 100 kN.
Sheathing System: Triple-layer HDPE (High-Density Polyethylene) coating provides UV resistance (tested to 3,000+ hours of QUV exposure) and anti-corrosion properties.
Temperature Tolerance: Operates reliably in -40°C to +70°C environments, validated through IEC 60794-1-2 testing.
2. Operational Advantages in Critical Scenarios
Power Line Parallel Deployments: Compatible with OPGW Earth Wire Systems, maintaining a 20 kV/m electrical field safety margin when installed near high-voltage transmission lines.
Urban-Rural Connectivity: Integrates with FTTH Fiber Splitters and Fiber Demarcation Boxes to extend gigabit-capable networks across challenging terrains.
Disaster Resilience: Survives wind speeds up to 150 km/h (IEC 61395 certified), minimizing service disruptions in typhoon-prone regions.
3. Streamlined Deployment Methodology
Phase 1 – Route Planning: Utilize GIS mapping tools to identify optimal pole attachment points, minimizing mid-span splices.
Phase 2 – Hardware Installation: Secure cable ends using ADSS Cable Fittings (e.g., suspension clamps, vibration dampers) compliant with IEEE 1138 standards.
Phase 3 – Network Integration: Terminate fibers via ODF Fiber Patch Panels or Optical Splice Closures, achieving ≤0.2 dB insertion loss through APC connectors.
Performance Metrics and Cost-Benefit Analysis
Independent field trials demonstrate the ASU system’s transformative impact:
Labor Efficiency: Reduces crew deployment by 40% compared to separate messenger wire installations.
Lifetime Cost: 35% lower TCO (Total Cost of Ownership) over 25 years, factoring in reduced maintenance and outage expenses.
Signal Integrity: Maintains ≤0.36 dB/km attenuation at 1550 nm, outperforming EIA/TIA-455-51A benchmarks.
When choosing an ASU cable, several crucial factors need to be taken into consideration.
First, determine the fiber count required for your project. ASU cables typically have a single loose tube and can accommodate a maximum of 12 optical fibers. If your application demands more than 12 fibers, you may need to explore other cable options. For instance, if you are setting up a small - scale local network with a limited number of endpoints, an ASU cable with an appropriate fiber count can be a cost - effective solution.
Secondly, consider the span distance. ASU cables are commonly used in spans of up to 80m, 120m, or 200m, such as ASU 80, ASU 120, and ASU 200 cables respectively. If the distance between poles is within 80m, an ASU 80 cable would be suitable, often used in urban areas where poles are relatively close.
Another aspect is the installation environment. Since ASU cables are totally dielectric, they can be used in ducts with electrical cables, making them ideal for installations where electrical interference needs to be avoided.
Finally, evaluate the cost - effectiveness. Weigh the price against the performance and durability requirements of your project. Sometimes, a slightly more expensive but higher - quality ASU cable can save costs in the long run by reducing maintenance and replacement needs.

Challenge: Rapid rural 5G rollout requiring cost-effective aerial pathways through mountainous terrain.
Solution: Pre-terminated ASU cables with Preconnectorized Terminal Boxes enabled plug-and-play installation.
Outcome: 68% faster deployment versus traditional OPGW systems, achieving 99.982% network availability post-commissioning.
