Abstract: PROBLEM TO BE SOLVED: To minimize the load transmitted to a fiber and the displacement forced to the fiber by providing a compliant core unit sealed in a support outer sheath. SOLUTION: This optical fiber cable 10 comprises three compliant core units 20 retained within an outer sheath 30. The core unit 20 comprises six bundled ribbons 24, each ribbon 24 is formed of a bundle of parallel optical glass fibers 22, in which six optical fibers are arranged in a row aligned in the lateral direction of each ribbon 24. Each layer of the ribbons 24 is sealed and supported in a compliant connecting structure consisting of a highly foamable polymer foaming body 26. The foaming body constituting the connecting structure is extruded molded around the layers of the ribbons 24. The core unit 20 is retained in the compressed state by the outer sheath 30, and the core units 20 are freely movable to the sheath 30 and to each other.
