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.
