Abstract:
An optical waveguide feedthrough assembly for passing at least one optical waveguide through a feedthrough member, comprising:at least one axially elongated surface defining an axially elongated optical feedthrough cavity, wherein the optical feedthrough cavity is defined by an outer dimension having at least one variation along the axial direction thereof; at least one optical waveguide received through the axially-elongated optical feedthrough cavity, and spaced relative to the axially-elongated surface to thereby define an axially elongated space between the at least one optical waveguide and axially elongated surface and extending from approximately one end of the optical feedthrough cavity to approximately another end thereof; and a sealant received within the cavity and extending between the at least one optical waveguide and the axially-elongated surface, and extending axially within the cavity from approximately one end to approximately another end thereof substantially entirely throughout the axially elongated space between the at least one optical waveguide and axially elongated surface, wherein the sealant exhibits adhesive properties at the interface of the sealant and the at least one optical waveguide, and at the interface of the sealant and the axially-elongated surface, to secure the at least one optical waveguide within the optical feedthrough cavity, and wherein the sealant cooperates with the at least one variation in the outer dimension defining the cavity to substantially prevent axial movement of the sealant relative to the axially-elongated surface.
