Abstract
A system (90) for routing a stack of fiber optic ribbons (100) includes a fiber optic cable (50) and a fiber guide tube (300). The fiber optic cable (50) includes a jacket (54) and a ribbon stack (110). The jacket (54) extends from a first end (56) to a second end (58). The ribbon stack (110) extends from a first end (112) to a second end (114). A jacketed portion (60) of the ribbon stack (110) is surrounded by the jacket (54) from the first end (56) of the jacket (54) to the second end (58) of the jacket (54). The fiber guide tube (300) extends from a first end (302) to a second end (304) along a central longitudinal axis (A1). The fiber guide tube (300) is positioned between the first end (56) of the jacket (54) and the first end (112) of the ribbon stack (110). The fiber guide tube (300) includes a round exterior (308) and an interior (310) with a rectangular cross-section (318). The rectangular cross-section (318) twists about the central longitudinal axis (A1) as the interior (310) extends from the first end (302) to the second end (304) of the fiber guide tube (300). A tubed portion (120) of the ribbon stack (110) is surrounded and twisted by the interior (310) of the fiber g…
