Abstract
PURPOSE: To achieve the prevention of the entry of harmful liquid or gas from the sludge, etc. existing in water bottom by filling clean water in the clearance in the corrosion-proof sheath and maintaining the balance of the water pressures of the inside and outside of the sheath in the water bottom or sea bottom.
CONSTITUTION: The twisted aggregate of optical fibers 4 and other intervening wire filaments 6, 7, 9 are provided and housed in one corrosion-proof sheath 10. Clean water 5 which does not give adverse influence upon the surrounding cable members is filled in the clearance 5, by which the water pressures of the inside and outside of the corrosion sheath in the water bottom and sea bottom are mutually balanced.
