Abstract : According to the patent, a fitting including a bushing extending through a high-pressure hull provides a multichannel data capability while possessing resistance to an extreme pressure differential. A cylindrical or tapered plug of glass having a graded refractive index or a cylindrical or tapered bundle of fiber optics is bonded within an accommodatingly shaped bore coaxially disposed in the bushing. Having such a configuration and manner of construction allows the fitting to be of reduced size with respect to contemporary electrical hull-penetrators, yet a much greater data transfer capability is provided and this fitting will stand up under the crushing pressures encountered at extreme ocean depths.
