Do outdoor fiber optic cables still need to be run through conduits
New fiber lines can be installed to pass through empty conduits if the bandwidth is needed in the future, thus no new path needs to be trenched. Underground fiber cables are generally pulled within a conduit that is buried underground, usually 1 to 2 meters deep, to reduce the possibility of being dug up. Lubricants are added to the outdoor cable design to reduce friction on high-pulling tension. The guide points out that improper selection is the primary cause of premature fiber optic network failures.
