| 主权项 | 1. A process for producing an optical fiber comprising a processing process where an optical fiber work made of a glass is held by a processing apparatus for an optical fiber work to be heated and processed, wherein in the processing process, vibration caused by crack or breakage of the optical fiber work in the heated state or vibration caused by crack or breakage of a glass body which is a portion of the processing apparatus for an optical fiber work and is in the state where the glass body portion is heated due to the heating of the optical fiber work is detected by using an acoustic emission sensor. | ||
