Abstract

PURPOSE:To prevent jerry from flowing out at cable connection part, and to improve airtightness, by packing an inclusion, impregnated with the jerry, in a gap among optical cables each having a unit sheath. CONSTITUTION:Optical fiber cable units 2 are stranded into one layer around the external circumference of a tension member 1. Each optical fiber cable 2 has optical fiber wires 4 in a metallic plastic laminate unit sheath 3. An inclusion 5 impregnated with jerry 8 is packed in a gap among the optical fiber cable units 2, a pressure winding layer 7 of nylon, etc., is provided around the external circumference of the optical cable core 6, and a metallic plastic laminate cable sheath 9 is provided around its external circumference. Therefore, the outflow of the jerry at a connection part is prevented and airtightness is improved.
