Beschreibung
Zusammenfassung:	Disclosed is a vapor axial deposition apparatus. The vapor axial deposition apparatus includes a first torch, a second torch, a temperature measuring unit and a controller unit. The first torch deposits soot on a distal end of a soot preform aligned with a vertical axis to thereby grow a core. The second torch deposits soot on an outer circumferential surface of the core to thereby grow a clad. The temperature measuring unit detects the temperature distribution of an end portion of the soot preform along the vertical axis. The controller unit determines first and second relative maximum temperatures T 1 and T 3, and relative minimum temperature T 2 between T 1 and T 3 in the detected temperature distribution, and controls T 1 to be within a predetermined range and the greater one of the difference (T 1 -T 2 ) and (T 3 -T 2 ) to not exceed a predetermined temperature.
