FRP Fiber Optic Cable Strength Members
DISLAB Composite — High-performance, non-metallic reinforcement components engineered to enhance tensile strength, durability, and reliability of fiber optic cables.
Crafted from glass fiber reinforced polymer (FRP), these rods provide superior mechanical support while eliminating issues associated with steel strength members: corrosion, electrical interference, and rodent damage. With a high tensile strength of ≥1100 MPa and low water absorption rate (≤0.1%), they ensure stable signal transmission in overhead installations to underground ducting. Available in diameters 0.5mm to 3.5mm with precision tolerance ±0.02mm.

Precision-engineered FRP rods — Each diameter from 0.5mm to 3.5mm is manufactured with tight dimensional control (±0.02mm) guaranteeing seamless integration into modern fiber optic cable production lines. The smooth surface and consistent roundness enhance manufacturing efficiency.
Our FRP strength members meet rigorous telecom standards, providing exceptional mechanical reinforcement without adding excessive weight. Perfect for ADSS, GYFTA53, and other cable architectures that demand stable, durable reinforcement.
Core Product Advantages
⚡ Non-Metallic, Non-Conductive
Eliminates electrical induction and corrosion risks. Ideal for power line environments and lightning-prone areas, preventing electromagnetic interference for stable signals.
💪 High Tensile Strength & Flexibility
Tensile strength ≥1100 MPa, robust support prevents stretching and breakage. Flexibility allows bending without kinking for curved cable routes.
🌊 Superior Environmental Resistance
Resists corrosion, moisture, and extreme temperatures (-40°C to +100°C). Water absorption ≤0.1%, ensuring performance in coastal, mountainous, or humid regions.
🐀 Rodent & Pest Damage Prevention
Hard, smooth FRP surface deters gnawing by rodents/insects, drastically lowering maintenance costs and preventing service interruptions.
➕ Additional advantage: Lightweight & Cost-effective — significantly lighter than steel, reduced cable weight and lower total cost of ownership.
Applications & Real-World Solutions
Our FRP strength members are deployed globally in mission-critical telecom infrastructure, from high-voltage power line communication to 5G backhaul networks.
The image shows a typical installation scenario alongside power transmission towers — non-metallic FRP eliminates induced currents and ensures safe, long-term reliability in high-voltage environments.
📡 Overhead & Underground Cables
ADSS / Armored overhead / underground duct cables — Provides tensile strength to support overhead spans, non-conductive design eliminates electrical interference.
⚡ High-Voltage Power Line Communication
Installed directly alongside power transmission lines; prevents induced currents and corrosion, enabling safe integration on power towers.
🏝️ Harsh Environment Telecom
Coastal networks, mountainous regions, industrial facilities — FRP resists saltwater, extreme temps, and moisture, plus rodent/insect resistance reduces repairs.
📶 5G & Next-Generation Networks
5G base station backhaul, FTTH networks — precise dimensional tolerance ensures compatibility with high-density fiber counts, stable mechanical properties maintain signal integrity.
🌟 Real Customer Case: Bulk Order for a Southeast Asian Telecom Operator
A major telecom operator in Thailand placed a bulk order with DISLAB Precision for 500,000 meters of 1.2mm FRP strength members for their nationwide 5G network expansion project. The project required non-conductive, corrosion-resistant reinforcement rods for ADSS cables installed across overhead power lines in coastal and rural areas.
Our team supplied rods with strict dimensional tolerances and surface quality checks. After 18 months of deployment, cables showed no signs of corrosion, stretching, or rodent damage even in humid coastal zones. The customer was impressed with consistent quality, leading to a follow-up order for FTTH network rollout.
Frequently Asked Questions
❓ How do FRP strength members compare to steel?
FRP is non-conductive, corrosion-resistant, and lighter. Eliminates electrical interference and rust-related failures. While steel may have higher tensile strength, FRP offers sufficient strength with non-conductivity and environmental resistance.
📏 What diameters are available?
We offer FRP strength members from 0.5mm to 3.5mm, common sizes: 1.0mm, 1.2mm, and 2.0mm. Custom sizes available upon request.
🔗 Are they compatible with all fiber optic cables?
Yes, designed for ADSS, armored, non-armored cables and widely used in GYFTA, GYFTA53, and ADSS cable designs.
🐭 How does FRP prevent rodent damage?
The hard, smooth FRP surface deters rodents and insects, unlike softer materials, reducing pest-related cable failures in rural/forested areas.
⚙️ Can rods be customized for specific applications?
Yes, we offer full OEM/ODM services including custom diameters, lengths, surface treatments, packaging, and material test reports tailored to your project.
🚚 What is MOQ & lead time?
MOQ 1000 meters; lead time 3-7 days for standard sizes, 7-15 days for bulk orders.
