Problems solved by technology

This not only requires strict requirements on the accuracy of the V-shaped groove itself, but also has strict requirements on the installation reference plane between the V-shaped groove and the movable workbench. Tolerance and shape tolerance, which increases the processing difficulty of V-shaped groove and movable table, and the processing cost is higher

Abstract

The invention discloses an optical fiber collimating device and an assembling method thereof and especially relates to the optical fiber collimating technology field. In existing optical fiber welding operation, a ''V''-shaped groove used for fixing an optical fiber is movably connected to a movable workbench, and an installation reference surface of the ''V''-shaped groove and the movable workbench is difficult to realize accurate collimation connection. By using the device and the method of the invention, the above problems are solved. The optical fiber collimating device comprises a substrate and a substrate support bench. The substrate is made of a silicon wafer or a ceramic material. The substrate is arranged on the substrate support bench. The substrate comprises a first optical fiber carrying portion, a middle interconnection portion and a second optical fiber carrying portion. Central axes of the first optical fiber carrying portion, the middle interconnection portion and the second optical fiber carrying portion are provided with V-shaped grooves which pass through each other and have V-shaped cross sections. The substrate support bench comprises a first workbench and a second workbench. Shapes of the first workbench and the second workbench are similar and the first workbench and the second workbench are parallel to each other.

Description

technical field [0001] The invention belongs to the technical field of optical fiber alignment, and in particular relates to an optical fiber alignment device and an assembly method thereof. Background technique [0002] At present, in the case of optical fiber fusion, in order to achieve low-loss splicing, it is necessary to achieve precise alignment of the optical fibers to be spliced ​​on both sides, that is, to achieve accurate alignment of the V-shaped grooves of the optical fibers on both sides of the fiber. Generally, the V-shaped grooves on both sides are made separately, and then installed in the movable workbench on both sides. This not only requires strict requirements on the accuracy of the V-shaped groove itself, but also has strict requirements on the installation reference plane between the V-shaped groove and the movable workbench. Tolerance and shape tolerance, which increases the processing difficulty of V-shaped groove and movable worktable, and the proce...
