Abstract:
A fabrication apparatus for fabricating a porous glass base material for optical fiber includes a core forming burner configured to form a core-corresponding portion corresponding to a core of optical fiber by depositing glass fine particles onto a hanging seed rod, a first clad forming burner configured to form a portion of a clad-corresponding portion corresponding to a clad of the optical fiber by depositing glass fine particles onto the core-corresponding portion, and a second clad forming burner configured to form a different portion of the clad-corresponding portion by depositing glass fine particles to form an outermost surface of the clad-corresponding portion. Here, a central axis of a flame ejected from the second clad forming burner has such a gradient that the central axis of the flame ejected from the second clad forming burner faces upward relative to a horizontal plane.

Claim (Index 4):
A fabrication method for fabricating a porous glass base material for optical fiber, comprising:\n forming a core-corresponding portion corresponding to a core of optical fiber by depositing glass fine particles onto a hanging seed rod; forming a portion of a clad-corresponding portion corresponding to a clad of the optical fiber by depositing glass fine particles onto the core-corresponding portion; and forming a different portion of the clad-corresponding portion by depositing glass fine particles to form an outermost surface of the clad-corresponding portion, wherein when a portion of the porous glass base material that has a target outer diameter is formed, a burner used to form the different portion of the clad-corresponding portion is tilted such that a central axis of a flame ejected from the burner faces upward relative to a horizontal plane.
