ABSTRACT:
An expansion joint with one or more communication medium bypass paths is described herein. At least some illustrative embodiments include a first axially flexible cylinder, one or more additional axially flexible cylinders positioned within the first cylinder, and first and second annular members each positioned at a opposite ends of, and each coupled to, the first cylinder and the one or more additional cylinders (the first and second annular members each including one or more apertures through each member). All cylinders concurrently extend and contract in axial length when the first and second annular members are respectively moved away from and towards each other. Annular spaces formed by each of the one or more additional cylinders and an externally adjacent cylinder, together with corresponding apertures of each of the first and second annular members, each provides at least one path for at least one communication medium.
