Problems solved by technology

[0002] At present, the end faces of the existing MT ferrules on the market are mostly flat. During the grinding process of the end faces, it is easy to cause warping and curvature on both sides of the plane, resulting in gaps during the use of the ferrule, resulting in increased insertion loss.
[0003] In the end face grinding process of the existing MT ferrule, the entire end face with a planar structure is ground. After grinding, the areas on both sides of the end face are easy to form arc surfaces, such as Figure 22 As shown, the end face of the entire ferrule is not flat, which will cause a gap when the ferrule is connected to the fiber and increase the insertion loss.

Abstract

The invention discloses a MT stub and preparation method thereof. The front end of the MT stub is a joint face which is provided with at least a first lug boss and at least two second lug bosses. The first lug boss is provided with a guide hole. The second lug boss is provided with an optical fiber patch hole. The joint face for MT stub has the first lug boss and the second lug boss, after grinding, because every lug bosses has the same cambered surface, the vertexes of multiple lug bosses are on the same horizontal line, the excessive optical loss due to the influence of the existing art is insured against occurring in using, therefore the insertion loss is reduced.

Description

technical field [0001] The invention relates to a communication device, in particular to an MT ferrule. Background technique [0002] At present, the end faces of the existing MT ferrules on the market are mostly flat. During the grinding process of the end faces, it is easy to cause warping and curvature on both sides of the plane, resulting in gaps during the use of the ferrule, resulting in increased insertion loss. [0003] In the end face grinding process of the existing MT ferrule, the entire end face with a planar structure is ground. After grinding, the areas on both sides of the end face are easy to form arc surfaces, such as Figure 22 As shown, the end face of the entire ferrule is not flat, resulting in a gap between the ferrule and increased insertion loss when the fibers are connected. Contents of the invention [0004] Based on this, the purpose of the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an MT ferru...
