PURPOSE:To provide the process for production of the optical fiber base material which obviates the failure of glass particulate layers during production. CONSTITUTION:This process for production of the optical fiber base material consists in depositing the glass particulate 2 for constituting a clad on a glass rod 1 for a core having at least a part to constitute the core by using an oxyhydrogen burner 3 along its axial direction while rotating the glass rod around its axis. The deposition thickness by one time of traversing of the burner 3 is specified to 1.0 to 2.0mm, more preferably to 1.5+ or -0.2mm in the above- mentioned process, the deposition thickness is specified in the prescribed region, by which the failure of the base material at the time of production is obviated. |
