Abstract
An improved pressure vessel comprises a tubular casing having an internal cavity and a first and second opening at each end. The internal cavity is divided into a first and second cylindrical plug region extending inward from the first and second opening and a hollow interior region. An optical component in the hollow interior has at least a plurality of optical fiber pigtails extending therefrom. A first and second cylindrical plug is force fit into the plug regions. At least one plug has a through-hole for receiving optical fiber pigtails. At least one plug has a ceramic adhesive plug formed by inserting adhesive into the through-hole and preferably filing the void space therein. The adhesive encapsulates the optical fibers passing through the through-hole. The plug has a channel machined into its outer circumference to receive an O-ring. A cap covers over and beyond the outer surface of the plug.
