Description
Technical Field
The invention relates to the field of optical fiber equipment, in particular to off-line continuous optical fiber grating carving coating curing equipment. The novel fiber bragg grating production mode is provided, and particularly the problems of repairing and reinforcing a coating after grating etching of an optical fiber and production continuity and efficiency are solved.
Background
At present, the traditional optical fiber grating is mainly etched in two modes, namely the grating is etched on an optical fiber drawing tower, and the grating is etched after off-line sectional stripping coating.
The first involved grating and coating curing processes all need to be done on a vertical tower. Because the optical fiber is formed by drawing after the optical fiber preform is heated by a high-temperature wire drawing furnace and melted, the temperature of the optical fiber is relatively high when the optical fiber is etched into a grating, and the optical fiber needs to be cooled or the production speed is reduced. Moreover, the optical fiber is not subjected to the test of optical physical properties, so that the optical fiber grating engraved on the drawing tower is easy to be unqualified, and waste is caused.
The second type of off-line grating is that the grating effect is ensured by the grating etching after the coating is stripped off in a segmented way, and the length of the fiber grating produced by the method is very limited, and the fiber cladding and the structural defect caused by grating etching are easily scratched when the coating is stripped off, so that the strength is rapidly reduced. Meanwhile, the optical fiber cannot be directly applied in engineering, secondary cladding is needed, and the production efficiency is extremely low. In short, the optical fiber is difficult to obtain timely and effective protection, repair and enhancement, and is a core problem for restricting the continuous production of the optical fiber grating under the line.
