A connector for joining a first fiber optic cable end and a second fiber optic end includes first and second connector ends adapted to receive the first and second fiber optic cable ends. Each connector end houses a plurality of termini for terminating the fiber optic cable ends. The connector also includes a first alignment feature and a second alignment feature. The first alignment feature includes a plurality of flanges formed on the first connector end to define a plurality of key openings and a plurality of key protrusions formed on the second connector end adapted to fit into the plurality of key openings to ensure proper alignment of the first and second connector ends. The second alignment includes a plurality of termini keys with each termini key being disposed on each of the termini and fitting into a key termini slot formed in the first and second connector ends for receiving the termini. The first and second alignment features ensure that the first connector end is properly aligned with respect to the second connector end and that each termini disposed in the first connector end is properly aligned with each termini disposed in the second connector end.

Fiber optic cable connectors for downhole applications

In an optical waveguide bulkhead feedthrough assembly, and method of making such an assembly, a housing includes at least one sealing surface and has a tubular member disposed therein that defines an axially elongated, annular surface, and the annular surface forms an axially elongated optical feedthrough cavity. An optical fiber or like waveguide is received through the axially-elongated optical feedthrough cavity, and is spaced radially inwardly relative to the annular surface to thereby define an axially-elongated annular cavity between the fiber and annular surface. An epoxy adhesive is introduced in its liquid phase into one end of the annular cavity, and is allowed to fill the annular cavity by capillary action. Upon filling the annular cavity, the epoxy hardens and cures and, in turn, adhesively secures the optical fiber within the tubular member. The annular surface defines a plurality of constrictions in the annular cavity to further secure the solid epoxy plug within the cavity, and prevent the plug from moving in response to axially-directed forces encountered in high pressure and/or high temperature applications. The optical waveguide bulkhead feedthrough assembly also includes an o-ring and compression seal to seal against mating bulkhead surfaces. The optical waveguide bulkhead feedthrough assembly further includes a compression nut disposed on the shoulder to fixedly mount the assembly within a bulkhead.
