A fiber management system for managing fiber optic cables within an enclosure. The fiber management system includes a trough having a plurality of slots for receiving and detachably retaining connectors of the fiber optic cables. A spool is coupled to the trough for coiling the excess length of the fiber optic cables. The trough is fixedly mounted to the inside of the enclosure to allow access to the interior of the enclosure without movement of trough without the fiber optic cables becoming entangled.
