Abstract:
    An optical fiber cable provided with a grooved spacer having on its outer circumference at least one SZ-spiral groove formed continuously along its longitudinal direction and at least one optical fiber tape accommodated in the groove of the grooved spacer, wherein the inverting angle, showing the rotational angle in the circumferential direction of the grooved spacer from one inverting portion of the SZ-spiral groove of the grooved spacer to the next inverting portion, is at least 180 DEG and wherein the optical fiber tape is accommodated in the groove in a state where the tape surface faces the bottom of the SZ-spiral groove at the center portions between inverting portions of the SZ-spiral groove and in a state where the tape side edges, which would be positioned at the inside of the bends of the groove of the inverting portions when assuming that the optical fiber tape were accommodated in the groove in a state where the tape surface faced the groove bottom at the inverting portions of the groove, face the groove bottom.
