Abstract
The utility model discloses a sleeve and an asymmetrical fiber interface assembly using the same. The sleeve includes a cylindrical sleeve body. A through groove penetrating through the sleeve body is arranged in the sleeve body in the length direction thereof and a step part protruding out of the sleeve body is arranged on the outer wall at one end of the sleeve body. The utility model also discloses the asymmetrical fiber interface assembly using the sleeve. To cooperate with the focal length of a laser in the module, insert distances of a ceramic inserting core in the fiber interface assembly and ceramic inserting core of a flexible connector in the ceramic sleeve are always designed to be asymmetrical in the design of the fiber interface assembly. Because of the different insert distances, a smaller stress is applied to the end with the smaller insert distance so that the ceramic sleeve moves under the influence of the end with the larger insert distance when the flexible connector is plugged or unplugged or when the cable wiggles, and as a result, the fiber interface assembly is proved to have a bad performance in a Wiggle (wiggle test). The sleeve and the asymmetrical fiber interface assembly using the same help to solve the problem that the fiber interface assembly has a bad performance in the Wiggle (wiggle test) of the asymmetrical design.
