FCC Shadow Raises Stakes for China’s Optical-Chip Supply Chain
An analysis republished by 36Kr, TMTPost and Cyzone examines how potential FCC restrictions on optical interconnect could affect China’s efforts to domesticate optical chips for AI infrastructure. It says China has made progress in 70mW and 100mW CW lasers, but remains less than one to two generations behind overseas leaders in high-end EML and high-power CW products, with yield and customer-certification hurdles. The article also warns that duplicated investment could create overcapacity in lower-end products, though those warnings are analytical rather than independently verified.
The report frames optical chips as a key link between AI-cluster expansion and China’s semiconductor-substitution strategy, highlighting the regulatory, manufacturing-yield and certification constraints facing domestic suppliers.
当AI 算力基建狂潮把光推上风暴眼，其中作为“光电转换的心脏”光芯片，自然被视作下一个千亿级蓝海市场。从 10G到 800G，再到 1.6T、3.2T，速率每迭代一次，光芯片的价值量与市场空间都在被推高。
坐穿多年的冷板凳，国内光芯片产业界也摩拳擦掌，将其视作继半导体之后又一个国产替代的核心战场。
在一二级融资潮达到最高的时候，迎面泼来一盆冷水：一方面FCC对光互联产业链的限制阴影挥散不去，从终端模块向上游芯片延伸的管制风险持续发酵；另一方面，光芯片自身的制造壁垒、产能瓶颈、良率爬坡难度，明显低于市场此前的乐观预期。

一、光芯片前景一片光明
光是AI基建中通胀属性最明显、确定性最高的板块，没有之一。
