摘要： An optical fiber submarine cable, which is provided with at least one coated optical fiber, a power supplying, pressure resisting layer of a pipe-like configuration, a tension resisting wire layer formed of a conductive material of relatively low conductivity and disposed in close contact with the power supplying, pressure resisting layer of the pipe-like configuration, and an insulator layer disposed around the tension resisting wire layer. The power supplying, pressure resisting layer is formed as at least one inner layer and an outer layer. The inner layer is formed as a single layer or composite layers by forming a tape-like good conductor material into a pipe-like configuration with its joint made a mere butt, or by assembling together a plurality of pressure resisting material segments equally divided in the circumference direction for at least one layer of the inner layer and having housed the above-mentioned at least one coated optical fiber in an optical fiber housing space defined centrally of the inner layer. The outer layer is formed by winding a metal tape on the inner layer.

摘要： An anchor for hooking and cutting a submarine cable comprises an anchor body part, a cable-hooking part and a connecting part, these parts being connected together into a form like a fishing hook. A cable-sensing device is provided on the inner side of the connecting part and spring-biased in the floating-up direction. A cutting device is provided for cutting and holding the submarine cable by being advanced from the anchor body part by hydraulic pressure making use of a force such as sea water pressure or a tugging force for raising the submarine cable externally applied to the anchor body part when the cable-sensing device is caused to sink against the biasing force in the floating-up direction by receiving the tension in the cable hooked on the inner side of the connecting part.

摘要： An optical fiber hermetic fixing structure of a feedthrough for an optical submarine repeater in which at least one optical fiber is introduced into a fluid-tight pressure-resistant housing of an optical marine repeater. Optical fibers are introduced and disposed in a through opening defined between a metal fiber-supporting guide and a metal sealing sleeve circumferentially of the fiber-supporting guide. The guide has a somewhat reduced diameter adjacent an end of the through opening so that the through opening has a greater transverse dimension along this part adjacent a seawater end of the feedthrough. This part of the through opening is filled with a low temperature melting metal about and between the optical fibers extending therethrough. The low melting temperature metal extends out of the through opening with a generally conical cross section configuration. A protective cover cap is disposed coaxial with the sleeve and fiber-supporting guide and through which the optical fibers extend longitudinally. The protective cover cap is filled with a liquid filler.
