Abstract: PURPOSE: A method of producing optical fiber preform using deposition burners is provided to suppress J ratio variation in a longitudinal direction and to allow J ratio variation to achieve but not to be achieved from a conventional method by setting a reciprocating speed v(mm/minute), an axis rotating speed r(rpm), and a burner interval L(mm) so that a value A expressed by the expression A = (r/v) x L is in a range 40>= A>= 8. CONSTITUTION: An apparatus structure in a soot deposition process includes a vessel(4), a starting rod(1), a plurality of glass particles synthesizing burners(2) arranged in the vessel(4) in such a manner that the burners(2) are arranged with a predetermined burner interval opposite to the starting rod(1). The starting rod(1) and the row of the burner(2) is relatively reciprocally moved. The starting rod(1) is also rotating. A turning back position of the reciprocal movement is moved in a predetermined direction by each one integral-th of the burner interval. When the turning back position is moved by the burner interval, the turning back position is moved in a reversal direction. By successively repeating this operation, the glass particles are deposited on the surface of the starting rod(1) in layer form, and the glass particle deposit(3) is produced.
