Frequently Asked Questions

What is HDPE corrugated optical fiber duct (C.O.D)?

HDPE corrugated optical fiber duct (C.O.D) is a compound-extruded dual-layer pipe made of polyethylene. It features a ribbed wall or silicon core inner pipe with an ultra-low friction coefficient and a high-pressure resistant, easy-to-bend corrugated outer pipe, designed specifically for protecting optical fiber cables.

What are the main advantages of C.O.D pipes over traditional optical cable protection pipes?

C.O.D pipes offer superior physical and chemical properties, a perfect dual-layer structural form, lower manufacturing costs, and more convenient construction compared to traditional pipes. Their flexibility and high-pressure resistance make them suitable for a wider range of topographical conditions.

Why is the silicon core inner pipe important in C.O.D design?

The silicon core inner pipe has an extremely low friction coefficient, which significantly reduces resistance when threading optical fiber cables through the duct. This makes cable installation faster, easier, and less likely to cause damage to the fiber during the blowing or pulling process.

In what topographical conditions can C.O.D pipes be used?

C.O.D pipes are designed to perform reliably under various topographical conditions, including straight runs, curved routes, hilly terrains, and areas with complex underground environments. Their flexibility and high-pressure resistance allow them to adapt to different installation scenarios.

Are C.O.D pipes suitable for long-term underground use?

Yes. The HDPE material used in C.O.D pipes offers excellent corrosion resistance, chemical stability, and durability, making them highly suitable for long-term underground deployment in optical fiber communication engineering projects.

Is C.O.D replacing traditional optical cable protection pipes in the industry?

Yes. Due to their comprehensive performance advantages — including better protection, lower cost, easier construction, and adaptability to diverse conditions — C.O.D pipes have become the first choice for optical cable protection and are gradually replacing traditional optical cable protection pipes across the industry.
