POTs and PANs Explores Conduit

As the article notes, while installers can lay fiber optic cables without using conduit, carrier-class conduits often use conduit for two primary reasons: (1) to protect fiber optic cables and (2) to make the cables easily accessible for future needs. The post explains the three methods installers user to feed the cables through the conduit. One method, the simplest of all, involves pushing the cables through conduit; it is commonly used for home and office installations.  For longer routes, installers can potentially use either of more complex pulling and blowing methods. Dawson discusses the advantages and limitations of each method along with unique characteristics of short and long installations that dictate which method is the best for a given job.  

For example, the most basic pushing method is practical for short runs inside of offices and homes because it can’t overcome snags and bends in conduit the way the pulling method can. On the other hand, while the pulling method is the most viable method for long outdoor installations, it is also more likely to cause damage to the cables during the install process. While installers can use the blowing method for longer routes in some circumstances, it requires installers to use a lighter than normal set of fiber cables, specialized conduit with a low-friction lining, and more care avoid physical obstructions in the conduit.
