Stocks in the optical communications sector are moving against the broader market trend.
At the time of writing, Hai Guang Xin Zheng (HKEX: 01191) has surged 18.24% to HK$195.1. Changfei Optical Fiber & Cable (HKEX: 06869) is up 3.51% at HK$247.8, while Lens Technology (HKEX: 06613) has gained 2.81% to HK$27.1.

Catalyst for the Move
The positive sentiment follows a recent announcement from Corning (NYSE: GLW). At an AI data center optical communications and interconnect technology conference held in Seoul, the company officially launched its Glass Bridge glass optical interconnect component.
This product is a glass optical connector designed to directly link photonic integrated circuits (PICs) with optical fibers, primarily targeting the co-packaged optics (CPO) and glass substrate semiconductor packaging markets.
In addition to the Glass Bridge, Corning showcased a next-generation CPO architecture that integrates glass substrates with optical interconnects.
Concurrently, the company introduced the GlassWorks AI platform, positioned as a comprehensive optical communications solution for AI data centers.
Further Index-Driven Momentum
Separately, it is noted that Corning has reportedly been removed from several value stock benchmark indices and added to key growth stock indices, including the Russell 3000 Growth Index, the Russell 1000 Growth Index, and the Russell Top 200 Growth Index.
Influenced by this development, Corning's shares closed up over 15% as of June 29th.
