A patch panel includes a cabinet and a cassette. A pair of cassette guides is positioned within the cabinet. The pair of cassette guides are spaced along a lateral direction such that the cassette is receivable between the pair of cassette guides. The cassette is slidable along a transverse direction on the pair of cassette guides. At least one of the pair of cassette guides includes a first rail and a second rail that are spaced apart along a vertical direction. The cassette is slidable along the transverse direction between the first and second rails. Each end of the first rail is cantilevered such that each end of the first rail is moveable along the vertical direction.
