Both ducted fiber optic cables and direct burial cables are used for fiber optic communications, but they are installed differently and used in different environments.
Ducted fiber optic cables are installed by placing the fiber optic cable in a duct. The conduit can be buried underground or overhead. The advantage of ducted fiber optic cable is that it protects the fiber optic cable from external physical damage and environmental influences, thus increasing the reliability and life of the cable. In addition, ducted fiber optic cables can also provide a viable solution for situations where obstacles such as buildings, rivers or roads need to be crossed.
Direct-buried cables, on the other hand, are fiber optic cables that are buried directly in the ground, usually requiring a trench to be dug underneath the pavement or soil, where the cable is placed and then covered. The advantages of direct buried fiber optic cables are that they are easy and quick to install, cost less, and do not require other ancillary facilities such as pipelines, so they are suitable for the construction of some long-distance communication lines.
Overall, ducted fiber optic cables are suitable for situations where the cables need to be protected from external physical damage and environmental influences, while direct buried fiber optic cables are suitable for situations where installation is easy and less costly. The decision on which type of fiber optic cable to choose should be based on actual needs.
