Central tube also known as which term?

In loose-tube fiber optic cables, the fibers are housed inside tubes that run along the length of the cable, with one tube located at the very center. That central channel is commonly called the core tube because it forms the core housing for the fiber bundles, literally the tube around which the cable’s fiber path is organized. The other terms describe different concepts: a single loose tube refers to a design with just one tube containing all fibers, which is a different configuration; unitube isn’t a standard designation in this context. So the central tube is best known as the core tube.
