Problems solved by technology

[0002] In existing optical communication systems, it is very common for optical devices to be packaged in airtight housings. The signal transmission of optical devices is usually conducted by flexible circuit boards. With the continuous improvement of optical communication systems, the transmission rate is 25Gbps and above. In rate transmission applications, the impact of high-frequency signal loss between the flexible circuit board and the airtight housing is becoming more and more obvious, which leads to the deterioration of the indicators of the transmitting end or receiving end and affects the overall transmission performance of optical devices

Abstract

The invention provides an optical device and a packaging method thereof. The optical device comprises a flexible circuit board, a tube shell and a conductive connecting piece. The flexible circuit board comprises a first reference ground bonding pad, a first signal bonding pad and a dielectric layer. The first reference ground bonding pad and the first signal bonding pad are positioned on the samesurface of the dielectric layer. The tube shell comprises a second reference ground bonding pad, a second signal bonding pad and a substrate. A first step surface and a second step surface adjacent to the first step surface are formed on the surface of one side of the substrate. On the height direction of the substrate, the second step surface is higher than the first step surface. the second signal bonding pad is located on the second step surface, the second reference ground bonding pad is located on the first step surface, the first signal bonding pad is connected with the second signal bonding pad, an accommodating space is formed between the first reference ground bonding pad and the second reference ground bonding pad, and the conductive connecting piece fills the accommodating space to connect the first reference ground bonding pad and the second reference ground bonding pad.

Description

technical field [0001] The present application relates to the technical field of optical communication, and in particular to an optical device and a packaging method thereof. Background technique [0002] In existing optical communication systems, it is very common for optical devices to be packaged in airtight housings. The signal transmission of optical devices is usually conducted by flexible circuit boards. With the continuous improvement of optical communication systems, the transmission rate is 25Gbps and above. In speed transmission applications, the impact of high-frequency signal loss between the flexible circuit board and the airtight housing is becoming more and more obvious, which leads to the deterioration of the indicators of the transmitting end or receiving end and affects the overall transmission performance of the optical device. Contents of the invention [0003] In view of this, the embodiments of the present application hope to provide an optical devic...
