Summary :

A few ppm of sodium and potassium contained in natural silica tube has been found to be removed during the deposition process in MCVD fiber, while remaining such alkalies in over-jacketed natural silica tube was pointed out to migrate into the germania doped core part during drawing process and to deteriorate resistivity against hydrogen.
