ABSTRACT:
A fluidblock/waterblock assembly for an undersea optical fiber cable includes a socket with a cavity. A rubber plug, shaped to fit into the cavity, is pierced with one or more holes for inserting an optical fiber or fibers. The rubber plug holding the fibers in the cavity is preloaded with an internal compressive stress which assures no leakage of fluid around or through the rubber plug throughout a range of external pressures ranging from zero to ocean bottom pressure and applied to the rubber plug.
