Abstract
An optical fiber cable in which optical fiber ribbon stack can be accommodated in a cylindrical space efficiently and which has excellent loss characteristic. A plurality of optical fiber ribbons,are stacked. Cushioning fillers,are disposed around the optical fiber ribbon stack,The optical fiber ribbon stack,and the cushioning fillers,are accommodated in a cylindrical member,The space factor of the cushioning fillers in the inner space of the cylindrical member as a remainder after removal of the optical fiber ribbon stack from the inner space is from 10 to 60%. Consequently, the optical fiber cable becomes excellent both in initial transmission loss and in loss increasing characteristic at a low temperature.
