An optical fiber unit for air blown fiber installation, including an optical fiber wire; an inner coating layer formed on an outer periphery of the optical fiber wire with a modulus of elasticity ranging from 0.98 to 196 MPa; an outer coating layer formed on an outer periphery of the inner coating layer with a modulus of elasticity ranging from 196 to 1960 MPa; and a foamed plastic layer formed on an outer periphery of the outer coating layer.

Metal filaments such as steel wires which has Young's modulus of 10,000 kg/mm,are provided longitudinally on a UV curable resin coated optical fiber. A resin covering layer is then formed on a resultant structure by coating ultraviolet curing resin and then curing the resin, whereby resulting in an extremely small optical fiber cord having a finished diameter of about 250 &mgr;m.
