1. An apparatus for fabricating a holey optical fiber, comprising:
a preform cover configured to seal one end of a holey optical fiber preform having a plurality of air holes disposed in a
substantially vertical orientation;
a gas supplier configured to supply gas into the air holes via the preform cover to prevent the air holes from being distorted;
a pressure regulator configured to control the amount of gas supplied from the gas supplier to be constant; and,
a heating means installed at the other end of the holey optical fiber preform configured to heat the other end of the preform
to draw an optical fiber.
