Shanghai Xihe Technology has released the registration version of its IPO prospectus for the STAR Market, describing itself as one of the world's leading suppliers of silicon photonic integrated chips. Its customers include leading optical module makers and cloud service providers, and its products are already shipping at scale into AI clusters and hyperscale data centers. According to estimates by optical module makers, silicon photonics solutions can reduce total cost by nearly 20% and the volume of components within the module by nearly 30% at the same data rate and distance.
