The invention describes a fiber optic module package which uses a metal-to-metal contact seal between a lid and a module housing. The metal-to-metal contact seal provides a sealing mechanism between the lid and the module housing. The module housing has a knife-shaped edge that can bite into a bottom surface of the lid when pressure is exerted on the lid. In a first embodiment, the module housing has a side slot in which an outer wall of the lid can enter which serves as a holding mechanism between the lid and the module housing. In a second embodiment, the module housing has an interior wall which can be pressed into a curved surface of the lid that serves as a holding mechanism between the lid and the module housing. In a third embodiment, multiple screws are inserted through multiple holes on the lid and into the module housing which serve as a holding mechanism between the lid and the module housing.

A fiber routing tray to hold, organize, and route fiber cables from external sources to other optical modules and optical components. The fiber routing tray mechanical device comprises a fiber entry block, fiber channel slot, retention bar with fiber clamps, fiber clamping slots, curved fiber routing fence, and a fiber exit opening. A retention bar with a contoured fiber retention clamps is used to hold fiber cables in place, provide a strain relief to a fiber cable, and distribute uniform clamping force on the fiber cable preventing insertion and return losses. Curved fiber channel slots with a preferable width help route fiber cables and prevent them from overbending. In addition, these fiber channel slots control the extension and retraction distance of the fiber cables during external fiber cable assembly. A curved fiber routing fence help route fiber cables and help prevent them from over-bending and tangling inside of the fiber reel tray. An exit opening allows fiber cables to drop below the fiber tray before the fiber cables are attached to the optical devices and optical modules.
