Notably, Tengjing Technology, Shijia Photon, and Zhongji Xuchuang all achieved historical highs during the trading session [1] Demand for Bandwidth - In the AI data center sector, there is a growing preference among customers for higher bandwidth network hardware. Increased bandwidth results in lower costs per bit, reduced power consumption, and smaller sizes. The rapid growth of 800G optical modules reflects the urgent demand for bandwidth driven by AI, with small-scale shipments starting at the end of 2022 and significant increases expected in 2023 and 2024. The demand for bandwidth from AI is considered limitless, and the high cost-performance ratio of networks suggests that 1.6T optical modules are likely to accelerate in application [1] Market Transition - According to CITIC Construction Investment Securities, the architecture for AI training networks is shifting from leaf-spine to fat-tree, leading to a substantial increase in the number of switches and optical modules. As communication data volumes rise, the speed requirements for optical modules are also increasing. The 800G optical modules are expected to ramp up production in 2023, with high growth anticipated from 2024 to 2026. The 1.6T optical modules are projected to begin shipments in 2025, with significant volume expected in 2026, indicating a prosperous cycle for the entire optical module industry chain characterized by simultaneous increases in both volume and price [1]
