Filed: 2001-08-06
Abstract: PROBLEM TO BE SOLVED: To stably and efficiently obtain a long-sized optical fiber which is made low in loss by reducing its Rayleigh scattering and has mechanical characteristics uniform in a longitudinal direction. SOLUTION: A glass fiber of a high temperature right after drawing is introduced into a vacuum vessel in the state of >=1,500 deg.C in inlet temperature into the vacuum vessel and while the glass fiber passes the inside of the vacuum vessel, the glass fiber is heat treated. At this time, the vacuum vessel is further preferably kept heated. If the glass fiber is introduced into the vacuum vessel and is kept at the prescribed temperature for the prescribed time or longer in the manner described above, there is no deposition of impurities to the optical fiber and crystallization can be suppressed. Accordingly, the slow cooling treatment of the optical fiber can be implemented without the hindrance of the reduction in the loss and without the formation of mechanically low-strength segments.
