ABSTRACT:
An optical fiber submarine cable, in which a high viscosity material of good wettability containing air gaps is filled in a space between an optical fiber cord having housed therein at least one coated optical fiber and a pressure resisting material layer having housed therein the optical fiber cord for protecting it from seawater pressure. The air gaps and the high viscosity material are arranged alternately with each other in the space at suitable intervals in the lengthwise direction of the cable. Alternatively, the air gaps are contained in the form of bubbles in the high viscosity material.
