Jiu Zhiyang: The company's independently developed space optical fiber amplifier has been applied to China Star Network, but has not yet been used in the Thousand Sails Constellation.

On April 8th, Jiu Zhiyang replied on the interactive platform that the company's self-developed space optical fiber amplifier has been applied to ChinaSat, but has not yet been used in Qianfan Constellation. Currently, the company has entered the white list of suppliers for ChinaSat, but the sales revenue from ChinaSat accounts for a relatively small proportion of the overall operating income, so it has no significant impact on the company's performance.
