AI CONVICTION THESIS

Zhongji Innolight is the undisputed global leader in high-speed optical transceivers (800G and next-gen 1.6T). As AI clusters scale, optical interconnects are the critical hardware bottleneck enabling high-speed, low-latency communication between GPUs. Zhongji Innolight holds a dominant market share with major US hyperscalers. The transition to advanced packaging and clustered compute creates an insatiable demand for their high-margin optical modules, offering explosive earnings growth at a highly reasonable valuation compared to US peers.

COMPANY DESCRIPTION
