Optical fiber cable and laying method thereof

A laying method of optical fiber cable comprising:

• push-inserting an optical fiber cable into an electric conduit,
• wherein the optical fiber cable includes an elongated optical element portion, the elongated optical element portion includes:
• an optical fiber including one or more plastic coated optical fibers, tight-buffered optical fibers or optical ribbon fibers;
• at least a pair of tensile strength members arranged in parallel at both sides of the optical fiber in a width direction of the optical fiber;
• and
• an outer jacket covering outer circumferences of the optical fiber and the pair of tensile strength members, and having a rectangular cross-sectional surface in which a long side is arranged in the width direction of the optical fiber and a short side is arranged in a thickness direction perpendicular to the width direction of the optical fiber,
• a frictional coefficient of the outer jacket is equal to or less than 0.20, and
• Shore D hardness of the outer jacket is equal to or more than 60, and
• a bending rigidity in the short side direction of the outer jacket of the optical fiber cable is within a range of 1.5×10−3N·m2 to 5.0×10−3N·m2.
