A fiber optic closure includes a panel assembly having at least two panels hinged to one another. The panel assembly includes a storage bay sandwiched between a pair of fiber management and connection assemblies. Each fiber management and connection assembly includes a sleeve connector panel that supports at least one sleeve connector array for establishing optical fiber connections. The splice panel having splice tube holders is also provided for establishing splices. The splice panel may further have at least one coupler cassette for splitting at least one input optical fiber into two or more output optical fibers. Preferably, the splice panel is positioned adjacent the sleeve connector panel so that a craftsperson can easily form custom sleeve connections within the fiber optic closure utilizing the splice panel to splice connectors onto selected optical fibers and utilizing the sleeve connector panel to interconnecting the connectors with opposing connectors.
