Fiber optic equipment assemblies employing non-U-width-sized housings supporting U-sized fiber optic modules, and related methods are disclosed. In one embodiment, the assembly may include the non-U-width-sized housing, at least one fiber optic equipment support member, and at least one U-sized fiber optic module. The non-U-width-sized housing may include an enclosure forming an internal cavity. The at least one fiber optic equipment support member may be disposed within the internal cavity and configured to support at least one U-sized fiber optic module. The at least one U-sized fiber optic module may be disposed within the at least one fiber optic equipment support member which may be disposed within the internal cavity. The at least one U-sized fiber optic module may have a height dimension wherein at least three of the at least one U-sized fiber optic module may be disposed within a U-unit height of unity.
