Abstract: A fiber organizer tray comprises a generally rectangular or oblong body having a first side and an opposite second side. The first side is configured to route and provide slack storage for a plurality of jacketed cables. The first side includes a winding cable guide that routes multiple jacketed cables a predetermined distance in a manner in which the multiple jacketed cables do not cross over themselves and do not experience a cable bend that violates a minimum bend radius of an optical fiber portion of the jacketed cable. The second side of the organizer tray is configured to route and splice a plurality of the drop cables to a plurality of optical fiber pigtails. The fiber organizer tray can be implemented in a telecommunication enclosure having a distribution management unit and a jacketed cable management unit disposed therein.
