Certain aspects of the disclosure relate to fiber optic cable systems, packaging configurations and methods that facilitate the effective use and installation of pre-terminated fiber optic cable. A fiber optic cable breakout arrangement can include a main cable, a branch cable that separates from the main cable, and an elongate protective sheath. Fibers of the branch cable can be packaged in the sheath to secure the fibers to the exterior of the main cable. In certain embodiments, the sheath can have a profile height extending generally radially outwardly from the main cable and a width that is greater than the profile height.
