Abstract

The invention is applied to the technical filed of optical communication, and provides a pluggable type adapter assembly for coupling of a collimating optical path. The pluggable type adapter assembly comprises an adapter 501, a lens assembly 502 and a protective sleeve 503. The lens assembly 502 is disposed inside the pipe-type protective sleeve 503, and one end of the adapter 501 is respectively connected with the lens assembly 502 and the protective sleeve; the end, which is connected with the protective sleeve 503, of an adapter metal piece 104 is a force fit end, the for fit end of the adapter metal piece 104 is in the form of a cylinder, and the diameter of the cylinder matches the internal diameter of the protective sleeve 503 to enable the adapter metal piece 104 to be inserted into the pipe-type protective sleeve 503; a ceramic insertion core 102 and a fiber 103 extend to the outside of the adapter metal piece 104 in terms of length and are connected with the lens assembly 502 inside the protective sleeve 503; and the lens assembly 502 comprises a third collimating lens 701 and a lens sleeve 702 which have the same in axial direction. According to the invention, when the pluggable type adapter assembly is coupled to a device shell assembly, parallel coupling of collimating light is realized, the efficiency during the parallel coupling of the collimating light is high, the coupling difficulty is low, and the coupling tolerance is large.

Description

technical field [0001] The invention belongs to the technical field of an optical transceiver module and a device in the field of optical communication, and in particular relates to a pluggable adapter assembly for collimating optical path coupling. Background technique [0002] In the field of optical communication, the collimated optical path is usually realized by using C-LENS (spherical lens) or G-LENS (gradient index lens) collimator structure. figure 1 It is a schematic cross-sectional view of a typical C-LENS collimator in the prior art, consisting of figure 1 It can be seen that the C-LENS collimator optical fiber 302 passes through the glass capillary 301, and is ground into a certain angle, and then coupled with the C-LENS 303 to convert the divergent light emitted in the optical fiber 302 into parallel light, and the glass sleeve 304 sets Outside the C-LENS 303 and the glass capillary 301, glue everything together. This kind of collimator structure is very matur...
