I guess this is just a POC system. Being a communication engineer, I fully aware the difficulties of photonics communications in unguided or non stationary medium.
This is a big break through.

According to the introduction of Xi'an Institute of Optics and Mechanics, the two satellite laser communication systems developed by it were successfully launched in Jiuquan on May 20 this year, and completed a series of work such as power-on self-checks, waiting for on-orbit testing.
From July 9th to 21st, the research team used a small number of satellite measurement and control arcs to carry out the on-orbit verification of the satellite laser communication system, and successfully achieved the stable construction of a dual-satellite link with a distance of 600km. Since then, the data transmission of the double-satellite communication payload has been carried out smoothly, and the high-speed data communication of the communication rate of 2.5Gbps has been successfully realized, and the system bit error rate is zero.

据西安光机所介绍，其研制的两套卫星激光通信系统于今年 5 月 20 日成功在酒泉发射，并完成开机自检等系列工作，等待在轨测试。
在 7 月 9 日至 21 日期间，研究团队利用少量卫星测控弧段开展了卫星激光通信系统在轨验证工作，成功实现距离 600km 的双星链路稳定建链。此后，双星通信载荷顺利开展数据传输，成功实现通信速率 2．5Gbps 的高速数据通信，并且系统误码率为零。
在 7 月 27 日至 30 日期间，西安光机所激光通信系统实现了通信速率 2．5Gbps、通信距离 600km、通信时间 145 分钟的星间长时间连续稳定通信（零误码），进一步扩展了星间激光链路承载实际数据业务的能力。
