Abstract: The optical fiber interconnection closure includes a housing defining an internal cavity and a fiber management frame disposed within the internal cavity. The fiber management frame includes a plurality of partitions for dividing the internal cavity into at least one and, more commonly, a plurality of slack storage compartments and a fiber interconnection compartment. The slack storage compartments are adapted to store slack lengths of optical fiber, while the fiber interconnection compartment is adapted to receive end portions of the optical fibers from the slack storage compartment such that the optical fibers can be interconnected therein. More particularly, one slack storage compartment can store slack lengths of unspliced express optical fibers, while another slack storage compartment can store slack lengths of the optical fibers that are spliced within the closure.
