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.

The present invention discloses an apparatus and method for a fiber optic housing and aligning device. A fiber optic housing and aligning device in accordance with the present invention comprises a housing, a directionally adjustable tubular casing that is mechanically coupled to a wall of the housing, and a collimator disposed within the directionally adjustable tubular casing, wherein the adjustable tubular casing comprises a convex spherical cap surface that mates with a concave seating surface of an opening within the wall and wherein the spherical cap surface may be attached to the housing by laser welding or by epoxy.

A latchable and pluggable module includes a top portion and a bottom portion coupled to the top portion, both the top portion and the bottom portion having side walls, the side walls of the top portion having narrowed portions at their front ends and the side walls of the bottom portions having recessed regions at their front ends such at a gap exists at the front end of each side of the module. The module further comprises a bail that rotates about or around two first pins inserted through the sides of the bail and the side walls of the bottom portion and two slider strips positioned and constrained to move between each recessed region and each corresponding narrowed portion, the slider strips coupled to the bail by two second pins passing through each bail side and a corresponding slider strip, each slider strip having an outwardly flared tab portion that may engage with an inwardly bent tab portion of a housing, cage or container.

An optical module box made of aluminum that has a reworkable glass-sealed fiber feedthru is disclosed. A fiber is inserted through a glass seal and a C-seal for hermetically sealing an opening in the optical module box. In a first embodiment, a module box employing a single-fiber fiber feedthru is described. In a second embodiment, a module box employing a 2-fiber feedthru is described. In a third embodiment, a module box employing a ribbon fiber feedthru is described. A module box having an opening with a single-fiber feedthru, comprising a C-seal; a glass sealed feedthru having a front tube and a back tube, the back tube of the glass sealed feedthru extending through the C-seal; and a fiber passing through the glass sealed feedthru and the C-seal, thereby hermetically sealed into the opening of the module box.

Optical modules employing glass-sealed fiber feedthru with C-seal

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.
