Abstract: A fiber optic cable can comprise a jacket enclosing an internal space. A member extending lengthwise within the space can provide two or more compartments. Each compartment can house a respective bundle of optical fibers that are color coded for distinguishing the fibers of an individual bundle from one another. Different compartments can house different number of optical fibers. The compartments can comprise indicia for distinguishing the compartments and/or the bundles from one another. The member can be formed by extrusion and can have removable or detachable fins. With the extruded member in a relaxed state, the compartments can be closed. A series of dies can insert the bundles of optical fibers in the compartments. The dies can manipulate the member to open the compartments for bundle insertion. Once the bundles are inserted in the respective compartments, the dies can release the member so the compartments close on the bundles.
