Abstract

PURPOSE: To sharply improve water pressure resistance characteristics and achieve reduction in weight by using the sheath of sandwich structure to the cable.
CONSTITUTION: The sheath 10 of the sandwich structure comprising by using plastics 12 as a central blank and disposing thin-walled pipes of iron of higher rigidity than said center blank on both sides thereof is applied on the outside of the aggregate 2 of optical fiber cores. Lamination techniques are employed for the thin- walled pipes 11 of iron and plastics 12 to increase adhesion power. The use of the sandwich structure integrated with the respective layers through bonding in this way enables the water pressure resistance characteristics to be sharply improved and enables the weight to be reduced.
