Korean Corrugated duct fiber optic energy-saving type

The Korean Corrugated Optic Duct (COD) is a flexible, durable, and energy-efficient conduit system designed for fiber optic and low-voltage cable installations, offering built-in multiple inner ducts and rapid, cost-saving deployment.

Overview

The Corrugated Optic Duct (COD), patented and manufactured by Korean companies such as Iteco (Optiroad), is a spiral-shaped corrugated conduit primarily used to protect fiber optic cables and low-voltage power cables . Its design incorporates 2 to 9 inner sub-ducts, allowing easy identification of cable types and reducing friction during cable installation . Both the inner and outer ducts are made of HDPE (High-Density Polyethylene), providing high flexibility and strength .

Key Features

• Built-in Multiple Inner Ducts: Eliminates the need for separate inner duct insertion, reducing installation time and labor .
• Flexibility and Coiling: Can be coiled in lengths up to 500–1,500 meters depending on model, enabling rapid deployment and minimal trench work .
• Durability: Resistant to pressure, impact, earthquakes, and land subsidence, with a working life of 50–100 years .
• Energy and Cost Efficiency: Quick installation reduces trench excavation, labor, and maintenance, contributing to energy savings and lower project costs .
• Environmental Benefits: Shallow and narrow trenches reduce environmental disruption and minimize construction energy consumption .

Standards and Testing

COD products comply with international standards such as ASTM F405, ASTM D2412, ASTM D1505, ASTM D882, ASTM D1693, ASTM D1603, ASTM D2122, and IEC 61386-21/22, ensuring reliability under various environmental conditions . The ducts are air- and water-tight, maintaining cable integrity during storage, transportation, and installation .

Applications

• Telecommunication Networks: Backbone fiber optic installations, high-speed internet infrastructure .
• Electrical Power and Metallic Cable Protection: Low-voltage and wide-diameter power cables .
• Urban and Industrial Projects: Suitable for areas prone to earthquakes or heavy traffic due to its compressive strength and flexibility .

Advantages Over Conventional PVC Ducts

• Faster installation with fewer labor requirements
• Reduced trench size and excavation energy
• Built-in inner ducts eliminate additional insertion steps
• Enhanced protection against mechanical stress and environmental hazards
• Long-term durability reduces maintenance and replacement energy costs In summary, the Korean COD system is a modern, energy-efficient solution for fiber optic and power cable installations, combining flexibility, durability, and rapid deployment to save both time and energy while ensuring long-term infrastructure reliability .
