Abstract: A fiber optic splice organizer secures a plurality of optical fiber splices between first and second optical fiber groups and secures slack associated therewith. The organizer includes a generally longitudinally extending lower base member that has lengthwise extending first and second opposing sides and widthwise extending first and second opposing ends. Slack optical fibers can be stored in looped configuration on the lower base member. A hinge is connected at one end and is adapted to pivotally mount the lower base member to a housing of a fiber optic splice closure. A member is positioned at the pivotally connected end of the base member for receiving groups of optical fibers. An upper splicing tray is positioned on the lower base member and at least one splice holder is positioned on the upper splicing tray for securing a plurality of fiber optic splices in side-by-side relation.
