What property of fiber-optic cable allows for fast pulling or blowing into flexible conduits?

The property of fiber-optic cable that allows for fast pulling or blowing into flexible conduits is the low coefficient of friction. This characteristic minimizes resistance between the cable and the conduit, enabling smoother and quicker installation processes when deploying fiber-optic lines. A low coefficient of friction reduces the amount of force needed to maneuver the cable through conduits, making it easier to handle, particularly over longer distances or when there are bends in the conduit.

In contrast, while high tensile strength is important for the durability and physical integrity of the fiber, it does not directly influence the ease of installation in conduits. Similarly, weather resistance and impact resistance are vital properties for the overall lifespan and resilience of the fiber optic cable in various environments, but they do not facilitate the installation process in the same way that a low coefficient of friction does.
