Summary:An optical fiber cable has a highly reduced diameter. The cable has a central strength member; a number of tubes containing loosely arranged optical fibers, each tube having a thickness, and each optical fiber having a coating; and a protective outer jacket, wherein the filling coefficient of optical fibers in at least one loose tube is >=45°/0. The tubes are made of a material having an elasticity modulus >=700 MPa; and the optical fibers are SM-R fibers having a microbending sensitivity <=4.0 DB.KM-1/g.mm-1 at a temperature of about -30° C. to +60° C. at about 1550 nm.
