Abstract
A re-enterable end-to-end hydrophone assembly which is at least partially transparent, so that the routing of the hydrophone fibers is visible during all phases of assembly and operation. The inventive hydrophone assembly includes a cylindrical sensing mandrel with at least one optical fiber wrapped around its outer wall, and an at least partially transparent oil-filled reference housing attached to the sensing mandrel. The reference housing contains an internal support for holding at least one end of the optical fiber, as well as other hydrophone components such as input couplers, output couplers, and the like. The inventive hydrophone assemblies can be easily disassembled, repaired, and reassembled, facilitating recovery and reuse of expensive optical components.
