ABSTRACT:
An apparatus for producing an optical fiber preform to perform the deposition process by modified chemical vapor deposition. The Apparatus comprises a main heat source location sensor (800) for detecting the location of a main heat source for heating a substrate tube100, an additional supporting device control part (1000) wiredly or wirelessly connected to the main heat source location sensor (800), and an additional supporting device (1100) wiredly or wirelessly connected to the additional supporting device control part (1000) for supporting the substrate tube (100). The present invention reduces the effective length of the substrate tube (100) by additionally supporting the substrate tube (100), thereby minimizing the deflection of the substrate tube (100). Particularly, it is possible to considerably reduce the deflection of the substrate tube at its initial part and thus to achieve a high deposition efficiency. Accordingly, it is possible to mass-produce an optical fiber preform of high quality.
