Fiber optic cables are typically buried underground to shield them from moisture, temperature fluctuations, and physical damage. This method provides protection and ensures the longevity of the cables. We can see from the perspective of layout aesthetic, direct burial is a better choice, for all fiber cables are buried underground and no need for poles. So buried laying is suitable for fiber optic cable installation in cities and places with this need. Each method comes with its own benefits and limitations, and your decision can impact not. For longer distances, fiber-optic cables are typically installed by hanging them between poles (aerial), laying them on the seabed (submarine), or burying them in the ground (underground).
