Optical transceiver and manufacturing method thereof

Abstract

The invention discloses an optical transceiver. The optical transceiver comprises a substrate, a positioning seat, a plurality of laser elements, a bracket and a plurality of lenses, wherein the positioning seat is arranged on the substrate and is provided with a pedestal and a pair of positioning columns; the positioning columns are arranged close to the two ends of the pedestal; the pedestal isprovided with a plurality of mounting holes which are formed between the positioning columns; the number of the laser elements is the same as that of the mounting holes; the laser elements are arranged on the substrate through the mounting holes respectively for receiving and transmitting photoelectric signals; the bracket is provided with a main body and a pair of side walls; the main body is provided with a pair of positioning holes which are matched with the positioning columns of the positioning seat for fixing the positioning seat and the bracket; and the lenses are arranged between the pair of positioning holes of the main body of the bracket and are arranged corresponding to the laser elements for receiving the signals transmitted by the laser elements. The invention also provides a manufacturing method for the optical transceiver. In the invention, the positioning seat with the positioning columns is matched with the bracket with the positioning holes for use, so that the laser elements which are arranged in reference to the positioning holes and the positioning columns can be accurately aligned with the lenses without any adjustment, and the manufacturing process is simple.

Description

technical field [0001] The invention relates to an optical transceiver and a manufacturing method thereof, in particular to an optical transceiver with precise alignment of an optical element and a lens and a manufacturing method thereof. Background technique [0002] Optical fiber communication has gradually become an emerging technology with development potential and is being widely used by people. It mainly transmits data through light, which can achieve faster and large enough communication bandwidth while maintaining the quality of transmission. Usually, optical fiber communication mainly uses optical transceivers to convert optical signals in optical fiber lines and electrical signals in electronic devices to each other, so as to complete fast data transmission. It can be seen that the performance of the optical transceiver directly determines the quality of data transmission. However, the alignment accuracy of the laser element and the lens in the optical transceiver...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that in the existing optical transceiver 100, the laser element 102 and the lens 105 not only have accumulated errors that are difficult to eliminate, but also the alignment process between the two is relatively complicated, which is not conducive to mass production of products
