An organizer (100) for fiber cable management comprises a generally planar base (105) having a splitter holding section (110), a slack and unterminated fiber storage section (120), and a splice and splice tray holding section (150). The splitter holding section (110) is configured to optionally hold one or more fiber splitters. The slack and unterminated fiber storage section includes a slack storage region (130) having a plurality of fiber routing structures (146a, 146b) to support and retain slack fiber and an unterminated fiber storage region having one or more spool type structures (142) to support and retain unterminated fiber separate from the slack fiber. The splice and splice tray holding section is configured to optionally hold one of a first fiber splice insert (160) and a splice tray holder (170) configured to engage one or more splice trays. A distribution box (200) for distributing optical fibers for communications includes a base, a cover, and the organizer described above.
