High-connection density and bandwidth fiber optic apparatuses and related equipment and methods are disclosed. In certain embodiments, fiber optic apparatuses are provided and comprise a chassis defining one or more U space fiber optic equipment units. At least one of the one or more U space fiber optic equipment units may be configured to support particular fiber optic connection densities and bandwidths in a given 1-U space. The fiber optic connection densities and bandwidths may be supported by one or more fiber optic components, including but not limited to fiber optic adapters and fiber optic connectors, including but not limited to simplex, duplex, and other multi-fiber fiber optic components. The fiber optic components may also be disposed in fiber optic modules, fiber optic patch panels, or other types of fiber optic equipment.

Presented herein is a tray for shipping, handling, and/or processing optomechanical components. The tray has a plurality of pockets arranged in an array, wherein each pocket is configured to hold one optomechanical component, and wherein each pocket includes at least one fiducial hole, at least one vacuum hole, a first cradle element configured to support a clip that attaches to one or more optical fibers of the optomechanical component, and a second cradle element configured to support a head of the optomechanical component. Also presented herein is a clip for an optomechanical component that includes a body having a top face and a bottom face, and a plurality of gripping elements arranged in pairs on the bottom face, each pair of gripping elements configured to support a barrel of an optical connector attached to a corresponding optical fiber of the pair of optical fibers.

A communication system may include a first chassis having first and second side walls and adapted to slidably receive therein a plurality of cassettes. A first cable hanger assembly may have a first side edge hingedly coupled to the first side wall of the first chassis, the first cable hanger assembly including a plurality of first hangers adapted to support cables thereon. An axis of rotation of the first cable hanger assembly may be substantially orthogonal to a direction in which the plurality of cassettes are slideable.
