PURPOSE: An optical fiber cable for air blowing installation is provided to prevent the optical cables from contracting by applying a plurality of pillars made of polymers between a plurality of strength members on the outside of a tube. CONSTITUTION: An optical fiber cable for air blowing installation includes a plurality of optical fibers(310), a tube(340), a plurality of pillars(330), a plurality of strength member(320), and an output coating(350). The optical fibers transmits an optical signal therein. The tube binds the optical fibers. The plurality of pillars enclose an outer circumference of the tube so that the tubes are spaced with a predetermined spacing. The plurality of strength member enclose the outer circumference of the tube between the pillars so as to improve a strength of the optical fiber cable. The output coating has a recess/concave shape so as to enclose the outer circumference of the pillars and the strength member.
