China Pioneers High-Speed Laser Links in Orbit between satellites

Amazing stuff! The news is dated! Google search can not find this Chinese company's website (i.e. Laser Starcom).

"A commercial Chinese firm has demonstrated ultrafast data laser transmission between two satellites, marking a step forward for the country’s communications megaconstellation plans.

Laser Starcom, a commercial aerospace firm established in Beijing in 2020, announced in March that it had achieved a 400-gigabit-per-second communications link between satellites. Its two satellites, Guangchuan 01 and 02, launched into low Earth orbit (LEO) in November last year on a commercial Zhuque-2 rocket developed by the Beijing-based Landspace company. The pair of Guangchuan spacecraft completed their optical transmission test on 18 March, according to a Laser Starcom statement, across a separation between satellites of 640 kilometers.

The company said the test established an enhanced intersatellite, or crosslink, communication system, supporting future high-bandwidth space networks. In addition to showcasing the growth of the nation’s satellite Internet development, the news further highlights the role of commercial companies in China’s growing space ambitions. ..."
