On November 26, Changguang Huaxin (688048.SH) released an announcement addressing the abnormal fluctuations in its stock trading. From November 24 to 26, 2025, the company's stock price exhibited a cumulative increase deviation of 30% over three consecutive trading days.

Lately, amid the escalating demand for computing power, the company has made significant strides in the optical communication sector. It has successfully achieved mass production of its 100G EML chips, initiated sample shipments of its 200G EML chips, and reached mass production and shipping levels for its 100G VCSEL, 100mW CW DFB, and 70mW CWDM4 DFB chips. However, the extent to which these products will contribute to this year's sales revenue and profits is still unclear. There are also inherent risks associated with the progress of product research and development, sample testing, product introduction, and market expansion efforts.
