Abstract

PURPOSE: To lower the breaking rate of an optical cable by placing a stringlike buffer material between two adjacent optical fiber bundles and covering them.
CONSTITUTION: Stringlike buffer material 5 is placed between every two optical fiber bundles 2, and bundles 2 and material 5 are preferably covered with low friction layer 4 and buffer layer 3 as outer layers. By this construction tension applied to the whole of the resulting optical cable and local tension to the optical fibers due to bending are relieved when the cable is laid, and the breaking rate of the cable is made very low.
