On October 20, 2026, Tencent released the 102.4T NPO Switch Design Reference Specification, making public its design solutions covering system architecture, chassis structure, fiber management, and software operations and maintenance. According to a report by C114, the switch is equipped with 32 3.2T NPO modules and 32 ELSFP external light source modules, providing 128 800G MPO16 optical interfaces. Tencent said that, compared with conventional pluggable switches, total system power consumption is reduced by about 1000W and end-to-end transmission latency is cut by nearly 100ns. So far there is only this single report, and whether the publication of the specification will drive large-scale deployment remains to be seen.
