Outside plant (OSP) fiber optic cable installations are typically point-to-point links with terminations inside buildings housing the communications equipment and intermediate connections in sealed closures. OSP cables may be installed by direct burial underground, pulled in underground ducts or conduit and mounted on poles in aerial installations.
