    摘要: A cable junction is provided for connecting two optical cables (110) submerged underwater, having a casing (130), an anchorage (120), a casing loading ring (150), an anchorage loading ring (145) and a seal ring (140). The casing (130) has a casing sealing surface (153). The anchorage (120) is arranged in the casing (130), and has an anchorage sealing surface (157). Circular ridges (260, 263) are provided in the casing sealing surface (153) and the anchorage sealing surface (157), respectively, for embedding into the seal ring (140). The anchorage (120) is rotatably coupled to the casing (130) by an anchorage/casing threaded joint (133). The casing loading ring (150) has a casing loading ring sealing surface (150a). The anchorage loading ring (145) has an anchorage loading ring sealing surface (145a). The seal ring (140) is arranged between the casing sealing surface (153) and the casing loading ring sealing surface (150a), and also arranged between the anchorage sealing surface (157) and the anchorage loading ring sealing surface (145a) for preventing hydrogen from entering the cable junction. The seal ring (140) is preferably made from a metal material such as copper, however, the scope of the invention is not intended to be limited to any particular material.
