Abstract

High-density fiber optic modules and fiber optic module housings and related equipment are disclosed. In certain embodiments, a front opening of a fiber optic module and/or fiber optic module housing is configured to receive fiber optic components. The width and/or height of the front opening can be provided according to a designed relationship to a width and/or height, respectively, of a front side of a main body of the fiber optic module and/or fiber optic module housing. In this manner, a high density of fiber optic components and/or connections for a given space of the front side of the fiber optic module can be supported by the fiber optic module and/or fiber optic module housing. The fiber optic modules and fiber optic module housings disclosed herein can be disposed in fiber optic equipment including but not limited to a fiber optic chassis and a fiber optic equipment drawer.
