A fiber optic telecommunications system comprising: a plurality of fiber optic connectors terminating a plurality of cables; a cable slack management module including a base configured for managing the cables that have been terminated to the fiber optic connectors, wherein the fiber optic connectors are positioned such that the fiber optic connectors can move relative to the base, the base further defining a first cable management spool an outer face of which is configured to contact the cables when the cables are pulled away from the base; a second cable management spool, within which the first cable management spool is located, wherein an inner face of the second cable management spool is configured to contact the cables when the cables are in a relaxed, non-pulled state, wherein the fiber optic cable slack management module defines a cable exit adjacent the first cable management spool and defined at least partially by the second cable management spool, the cable exit defined by a channel positioned between the first and second cable management spools (32, 62); and a plurality of removable trays mounted to the base in a stacked configuration, each of the trays configured for managing cables, wherein an inner face of an outer peripheral wall of each tray defines the second cable management spool, wherein the cables terminated by the fiber optic connectors are provided within the cable slack management module such that the cables transition from a common plane when entering the base of the cable slack management module to a plurality of different levels provided by the stacked trays, wherein the cables terminated by the fiber optic connectors are provided within the cable slack management module such that the cables are looped once around within the trays, wherein the cable exit is defined both adjacent the first cable management spool and at least partially by the inner face of the outer peripheral wall of each tray, wherein the cable slack management module defines a cable input at a rear of the base and wherein the cable exit is defined at a front of the base, wherein the cable input and the cable exit are generally aligned when viewed in a front-to-back direction, wherein each of the trays defines a ramp for transitioning the cables within the cable slack management module from the common plane when entering the base to the different levels provided by the stacked trays, the ramps of the trays being adjacent the first cable management spool and the cable exit of the cable slack management module. a plurality of fiber optic connectors terminating a plurality of cables;
