In the age of big data, as people's demand for communication system bandwidth continues to increase, the data transmission capacity of communication equipment is also constantly improved. Nevertheless, today's huge data transmission business is still based on optical fiber transmission. In optical fiber transmission, such as next-generation mobile networks, fixed access networks, metropolitan area networks, and data centers, 10G transmission still occupies a mainstream position. Therefore, the 10-Gigabit optical transceiver that realizes photoelectric conversion also occupies a very important position.
