Adapter assembly for optical module and optical module

Abstract

The present invention provides an adapter assembly enabling the optical power to be more stable and the optical module with the adapter assembly, the assembly error among the adapter shell, the optical fiber insertion core and the PIN needle is effectively reduced, the requirement for the machining precision of a shell structural part is reduced, the optical power of the optical module is more stable, and the adapter assembly comprises the adapter shell and the optical fiber insertion core; a slot matched with the optical fiber insertion core is formed in the adapter shell, a plurality of optical fiber insertion holes are formed in the optical fiber insertion core, the optical fiber insertion core comprises a slot part and a limiting part, the slot part can be inserted into the slot, and the limiting part can limit the installation of the optical fiber insertion core in the slot; and clamping hooks are arranged on the adapter shell and located on the two sides of the front portion of the inserting groove respectively, the clamping hooks can be matched with the limiting parts of the optical fiber inserting core to limit the optical fiber inserting core, the optical fiber inserting core is further provided with PIN needle positioning holes, and the PIN needles are installed in the PIN needle positioning holes.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an adapter assembly and an optical module for making optical power more stable. Background technique [0002] Adapters for existing optical modules such as figure 1 As shown, the adapter is composed of three parts: a housing C, an optical fiber ferrule B and a PIN needle assembly A, and positioning is performed by setting a limit groove on the structural member D of the optical module housing. Because there are certain errors when the components of the adapter are matched, they will not be completely assembled to the ideal position, and there will also be errors when assembling the adapter and the shell structure. After these errors accumulate, it will cause the adapter structure to be impossible during the fiber insertion process. It is inevitable that the optical power of the optical module will not be stable. Contents of the invention [0003] In view of the ...

Problems solved by technology

Because there are certain errors when the components of the adapter are matched, they will not be completely assembled to the ideal position, and there will also be errors when assembling the adapter and the shell structure. After these errors accumulate, it will cause the adapter structure to be impossible during the fiber insertion process. Avoid the phenomenon that the optical power of the optical module is unstable
