High-precision fiber optic tapered equipment

Abstract

The invention provides a high-precision fiber taper equipment, which belongs to the field of precision equipment manufacturing; the invention comprises: an electrode heater, an optical fiber, a suspension frame and a base; the upper end of the optical fiber is mounted on the suspension frame, and the optical fiber is connected to the suspension frame. The horizontal plane is vertical; the suspension frame is also provided with an electrode heater that can be rotated horizontally and can be moved up and down; the base is provided with a telescopic rod that can move in the vertical direction, A pulling head in contact with the fused optical fiber; the pulling head is located below the optical fiber and corresponds to the optical fiber. The invention rotates and heats the end of the optical fiber through the electrode heater, and can insert the end of the optical fiber through the pulling head; and then pulls the end of the optical fiber through the pulling head, thereby realizing the simplified operation of tapering the optical fiber.

Description

technical field [0001] The invention relates to the manufacturing technology of precision machining equipment, in particular to a high-precision optical fiber tapering equipment, which belongs to the technical field of precision machining. Background technique [0002] In the manufacturing process of optical fiber preform, in order to effectively draw the optical fiber preform into optical fiber, reduce the glass loss at the beginning of the optical fiber, and shorten the forming time of the drawing preform fusion cone, it is usually necessary to draw the lower end of the preform into a streamline cone head, The shape of the cone head will also affect the drawing pass rate of the optical fiber preform. During the process of drawing the optical fiber preform, the change of the drawing tension and the drawing speed will cause the fluctuation of the fiber diameter, the cut-off wavelength of the fiber, and the mode field diameter. , the phenomenon that the zero dispersion wavele...
