    Product Details

    HDPE corrugated optical fiber duct (C.O.D) is made of polyethylene, which is compound extruded with a ribbed wall pipe or silicon core pipe with an extremely low friction coefficient as the inner pipe and a high-pressure resistant, easy-to-bend corrugated pipe as the outer pipe. Its comprehensive performance is incomparable to any previous optical cable protection pipes. With excellent physical and chemical properties, a perfect structural form, low manufacturing cost and convenient construction, C.O.D pipes have become the first choice for optical cable protection pipes under various topographical conditions, and have a trend of gradually replacing the traditional optical cable protection pipes, providing a reliable protection solution for optical fiber communication engineering.

    C.O.D pipes combine a low-friction silicon core inner pipe with a high-pressure resistant corrugated outer pipe — delivering superior protection, flexibility, and cost efficiency for optical fiber communication infrastructure across all terrain types.

    Frequently Asked Questions
    Q
    What is HDPE corrugated optical fiber duct (C.O.D)?
    HDPE corrugated optical fiber duct (C.O.D) is a compound-extruded pipe made of polyethylene. It features a low-friction silicon core inner pipe and a high-pressure resistant corrugated outer pipe, designed specifically to protect optical fiber cables in various installation environments.
    Q
    What materials are used to manufacture C.O.D pipes?
    C.O.D pipes are made from high-density polyethylene (HDPE). The inner pipe is either a ribbed wall pipe or a silicon core pipe with an extremely low friction coefficient, while the outer pipe is a corrugated structure engineered for high-pressure resistance and flexibility.
    Q
    Why is the silicon core inner pipe important in C.O.D ducts?
    The silicon core inner pipe provides an extremely low friction coefficient, which allows optical fiber cables to be blown or pulled through the duct with minimal resistance. This significantly reduces installation time and effort, especially over long distances or complex routes.
    Q
    In what conditions can HDPE corrugated optical fiber ducts be used?
    C.O.D pipes are suitable for a wide range of topographical conditions, including direct burial in flat terrain, hilly areas, and other complex environments. Their flexibility and high-pressure resistance make them adaptable to virtually any optical fiber communication project.
    Q
    How do C.O.D pipes compare to traditional optical cable protection pipes?
    C.O.D pipes outperform traditional optical cable protection pipes in almost every aspect — including physical strength, chemical resistance, installation convenience, and cost-effectiveness. As a result, they are gradually replacing conventional pipe solutions and have become the preferred choice in modern optical fiber communication engineering.
    Q
    Are HDPE corrugated optical fiber ducts cost-effective?
    Yes. C.O.D pipes offer a low manufacturing cost combined with easy and efficient on-site construction. Their durability and long service life further reduce maintenance expenses, making them a highly cost-effective solution for optical fiber infrastructure projects of all scales.
