1. Technical Field
The present disclosure generally relates to optical transceivers, and more particularly to a packaging method of an optical transceiver.
2. Description of Related Art
Optical communications has become increasingly popular and is widely used in information transmission. Generally, optical transceivers are used in optical communicating device to perform a conversion between electrical signals and optical signals. An optical transceiver comprises a plurality of laser components and a plurality of lenses. Definition of position between the laser components and the lenses effects performance of transmitting information of the optical transceiver. Therefore, how to make an exact definition of position between the laser components and the lenses is an important problem in study.
Therefore, a need exists in the industry to overcome the described limitations and reduce the size of the electronic device.
Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

In this embodiment, the side walls 62 are affixed onto the substrate 20 to secure the bracket 60 to the substrate 20. The driving chip 50 and the positioning seat 30 are located between the pair of side walls 62.
In this embodiment, the pair of positioning posts 32 snugly engage with the pair of positioning holes 610, and the plurality of laser components 40 snugly engage with the plurality of receiving holes 310. The laser components 40 can be exactly positioned on the substrate 20 due to the engagement between the laser components 40 and the receiving holes 310 of the positioning seat 30. The bracket 60 can be positioned on the substrate 20 due to the engagement between the positioning posts 32 of the positioning seat 30 and the positioning holes 310. The positioning seat 30 acts as a common reference for positioning the laser components 40 and the bracket 60 to make a definition of position between the laser components 40 and the lenses 70.
