Abstract
A design for an underwater splice closure is disclosed that protects splices essentially independent of operating depth, while allowing for ease of use and low-cost manufacture. The primary splice housing consists of an upper and a lower half-cast of beryllium copper. The splices are made and then organized along a series of interior trays mounted from risers attached to the lower half of the housing. The two halves bolt together. An end-seal assembly contained on the lower half of the closure, and consisting of a series of O-ring applications, receives the sheathed cable and directs it to a mounting means which secures the sheath to the lower half of the splice closure. The invention is particularly adapted to optical fiber splice closures which require protective fill.
