Hello: I have read previous questions from investors. Your company can produce all kinds of high-speed optical chips. How much is the company's current revenue from optical chips?

XD Sanan Optoelectronics: The company's optical technology business continues to deepen its access network, data communication, telecommunications transmission, intelligent AI, and consumer (optical sensing, medical beauty, power, etc.) fields. It actively expands the automotive lidar chip market and deploys 905nm EEL/VCSEL and 1550nm narrow linewidth laser chips. Among them, the 1550nm narrow linewidth laser chip technology is at the leading level in China. By the end of 2022, the company's PD chip domestic market share exceeded 50%, and 10GDFB chips have been delivered in batches to mainstream customers in the market. Multi-wavelength VCSEL products mainly used in data centers have been developed and delivered in batches, becoming the exclusive chip supplier in China, filling the gap in this field in China, and the overall optical technology business is developing steadily.
