Abstract: A system for protecting optical components is disclosed. The system includes an optical tray with at least one optical component and a cover that can be mounted on the optical tray. The optical tray includes a base with an aperture and a door assembly mounted on the base. The aperture has an area that is sufficiently large for access to components on the optical tray. The door assembly has at least one door having a surface area sufficient to cover at least a portion of the aperture. The cover protects the components and contents of the optical tray against external shock, including mechanical, electrical and electromagnetic impulses, yet allows easy access to these components and contents when desired.
