Fiber optic cable assembly

The present disclosure relates to a fiber optic cable arrangement including a plurality of fiber optic cables. At a central section of the fiber optic cable arrangement, the fiber optic cables are arranged in a core and are protected by an outer split sleeve. At end sections of the fiber optic cable arrangement, the fiber optic cables form connectorized pigtails. Transitions form demarcation locations (e.g., fan-out or break-out locations) between the central section and the end sections. The transitions include one or more tape layers and/or one or more heat shrink layers.
