Assemblies and methods are provided for facilitating fiber optic patching. More particularly, the assemblies and methods generally involve mounting fiber optic patch ports arranged along a horizontal plane with respect to a tray. The tray is movably positioned within a cabinet enclosure, e.g., in a pivotal or translational (sliding) relationship, thereby providing easy access to the ports. The horizontal configuration advantageously increases fiber optic patching density within a cabinet structure while maintaining port accessibility.
