WATERPROOF CABLE AND METHOD OF THE PRODUCTION THEREOF

摘要

: The invention provides a waterproof optical fiber cable for use in a communication system. To form the cable, one or more optical fibers are loosely placed in grooves formed along a spacer and a plurality of filled portions are formed in each of said grooves by being filled with dampproof material at predetermined intervals so as to provide a plurality of filled portions and unfilled portions alternately. By this means undesired local bending of the optical fibers can be prevented. Also a method of making the waterproof optical fiber cable having such filled portions and unfilled portions is disclosed.
