Abstract
A submarine optical fiber cable includes inner and outer dams at suitable intervals for limiting water flow in the cable. The outer dams are formed in a space between inner and outer metal tubes of a pressure resisting sheath of the cable, and the inner dams are formed in the inner tube in which an optical fiber unit is enclosed. Each dam is made of a sticky compound or a jelly of plastics resin which is loaded at the dam position. The cable is also provided with a scale which represents distance from one end of the cable.
