Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] In the prior art, there are many assembly difficulties in the application process of the APC ferrule in the module. The reason is that there is a hard connection between the optical component and the PCB board, such as figure 1 and figure 2 As shown, the transceiver integrated optical component includes TOSA component and ROSA component. The 5 pins of ROSA are directly soldered to the PCB board, and the 4 pins of TOSA are directly ...

Abstract

The invention discloses an optical module comprising an optical insertion core, an insertion core holder, and a round tube body wherein the insertion core holder is fixedly arranged on the external surface of the optical insertion core. The optical end face of the optical insertion core extends out from one end of the insertion core holder; the optical end face of the optical insertion core is an inclined face; one end of the optical insertion holder away from the optical end face and the round tube body are fixed; the optical module also comprises a circuit board, a flexible connector, a support, and a housing. The round tube body is connected with the circuit board through the flexible connector; the outer surface of the insertion core holder is further provided with a fixing component. The fixing component cooperates with the support and the housing respectively for fixations. When the optical insertion core of the optical module is docked with the insertion core of the optical connector, the position movement of the insertion core holder is restricted as the fixing component on the insertion core holder, the support and the housing of the optical module are fixed. Therefore, angle deviation generated from the docking of optical end faces can be avoided, so are the insertion loss and damage.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module. Background technique [0002] Among the optical module products, there are many types of optical interfaces of the optical transceiver integrated module, including FC interface, SC interface, LC interface, MU interface, MT interface, MPO / MPX interface, etc. These optical interfaces can be connected to optical fiber connectors. The optical fiber ferrule in the optical module is connected with the optical fiber ferrule of the optical fiber connector through the optical interface of the module. Common optical fiber ferrules include PC, UPC, and APC. When the optical fiber ferrule of the optical fiber connector is used in conjunction with the optical fiber ferrule of the module, the most commonly used is the PC optical fiber ferrule or the UPC optical fiber ferrule, because the optical end surface of the PC ferrule or the UPC ferrule is a plane or a s...
