Cutting method for upper and lower grooving of 2DV groove cover plate

Abstract

The invention discloses a cutting method for upper and lower grooving of a 2DV groove cover plate. The cutting method comprises the following steps: S1, preparation: firstly a glass plate and a cover plate are prepared, then grooves are formed in the glass plate and the cover plate, and it is ensured that the sizes of the grooves in the glass plate and the cover plate are the same; S2, positioning holes are formed, specifically, a positioning hole A is formed in the top face of the glass plate, then a positioning hole B is formed in the bottom face of the cover plate, and it is guaranteed that the positions of the positioning hole A and the positioning hole B are the same; S3, optical fiber grooves are formed, then a plurality of sets of optical fiber grooves are formed in the groove, and the optical fiber grooves are mainly used for containing optical fibers; and S4, vertical positioning is carried out, and then a glass block is installed in a groove between the glass plate and the cover plate for fixation, so that the optical fiber is vertically limited. The V-shaped groove manufactured in the method can meet the positioning requirement for the horizontal positions of small-spacing upper and lower rows of optical fibers, meanwhile, the positioning of the optical fibers in the vertical direction can also be met, the practicability is high, and the progress is remarkable.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a cutting method for cutting up and down grooves on a 2DV groove cover plate. Background technique [0002] Optical fibers are generally used for communication, and when the optical fiber is fixed, it is often necessary to use a glass plate and slot the glass plate to fix the optical fiber. However, the V-groove opening technology for fixing double-row optical fibers is generally on the same piece The upper and lower sides of the glass plate are grooved. This method cannot accurately fix the horizontal position of the upper and lower rows of optical fibers, and it is only applicable to the situation where the distance between optical fibers is large, so it needs to be improved. Contents of the invention [0003] The object of the present invention is to provide a cutting method for cutting up and down grooves on a 2DV groove cover plate, so as to solve the problem...
