What are smaller, flexible pathways usually used inside a conduit called?

In the context of conduit systems, the term "inner duct" refers to the smaller, flexible pathways that are utilized within a conduit. Inner ducts are specifically designed to accommodate smaller fiber optic cables or other types of wiring, allowing for efficient organization and protection within the larger conduit. This is beneficial because it enables multiple cables to be housed within a single conduit run, maximizing space and reducing the potential for damage to the cables.

Inner ducts facilitate easier installation, maintenance, and upgrades of the cabling infrastructure since they allow for the routing of multiple cables without the need for larger conduit systems. This modular approach can help in optimizing equipment layout and enhancing the overall performance of the communication system.

The other terms such as "microduct" and "subduct" refer to specific types of inner duct systems as well, but in this context, "inner duct" is the more encompassing term that is commonly used in the industry. The term "pipe conduit" does not accurately reflect the smaller pathways used within a conduit, as it typically refers to the outer structure that encases these smaller ducts.
