Optical fiber submarine cable |
摘要 |
An optical fiber submarine cable comprising at least one optical fiber. A pipe-like pressure resisting layer is produced by forming a tape-like pressure resisting material into a pipe-like configuration with the optical fiber inserted therein. The pressure resisting layer has butt ends in its cross section, and a waterproof insulator layer is disposed closely around the pipe-like pressure resisting layer for maintaining the pipe-like configuration of the pipe-like pressure resisting layer and for preventing seawater from entering into a gap between the butt ends.
