    • PROBLEM TO BE SOLVED: To provide a method for activating an inner surface of a hollow glass substrate tube that never causes an increase in unevenness of the inner surface.SOLUTION: The present invention relates to a method for activating an inner surface of a hollow glass substrate tube for manufacture of an optical fiber preform. The method includes the steps of: i) vapor-depositing many activated glass layers on the inner surface of the hollow substrate tube through a PCVD process, the activated glass layers having a thickness of 10-250 micrometers; and ii) at least partially removing the activated glass layers vapor-deposited in step i) through an etching process, the activated glass layers vapor-deposited in step i) being removed by up to at least 30%. The method implements the etching step not on an initial substrate tube itself but on PCVD vapor-deposited layers so as to reduce or completely remove negative effects of etching, or generation of surface unevenness while maintaining advantages of the etching process such as improved sticking.
