摘要： PROBLEM TO BE SOLVED: To provide a method and a manufacturing apparatus for a low-loss optical fiber, whose structure is simpler and whose working efficiency is higher than those with a conventional technology. SOLUTION: An optical fiber is accepted as a product when disappearance of the peak of absorption of the wavelength of 630 nm band by non-cross linked oxygen defect (NBOHC) appearing before a deuterium processing is confirmed on the deuterium processing. The confirmation is performed by measuring a transmission loss in the range of wavelengths from 600 nm to 1,100 nm at every prescribed time interval or at arbitrary times during the deuterium processing, or by continuously measuring the transmission loss during the deuterium processing by making light incident from a single light source having 630 nm. By performing the above confirmation, a conventional hydrogen processing is unnecessary and a step of manufacturing the low-loss optical fiber is made remarkably efficient.
