Zonghui Xinguang's breakthroughs and developments in the field of optical communications

In the field of optical communications, Zonghui Xingguang has achieved sales of 50G PAM4 VCSEL chips in 2023. At present, the 100G PAM4 VCSEL sample indicators are aligned with those of international leading manufacturers, and are superior to international leading manufacturers in terms of spectrum width indicators, which is conducive to longer-distance signal transmission. It is expected that product verification will be completed by the end of this year and mass production will begin in 2025 to meet the needs of the AI ​​market, which is in short supply.
