Coractive, a specialty optical fiber manufacturer based in Québec City, Canada, is accelerating R&D and production-capacity expansion for high-performance optical fibers targeting AI infrastructure and next-generation optical networks. The company will focus on industrializing hollow-core fiber (HCF) and polarization-maintaining (PM) fiber technologies as data center and telecom networks transition toward 800G and 1.6T optical transmission.
The expansion builds on investments by Coractive parent Han’s Laser across the optical fiber supply chain. According to Coractive, Han’s Laser recently committed nearly US$400 million across two initiatives: establishing a production platform for optical preforms and fibers and acquiring a 51% stake in LinFiber Technology, a developer of high-performance hollow-core fibers. Coractive said it will use resources from its parent company’s broader photonics supply chain while continuing to operate independently in Canada.
Coractive plans to expand its Québec City production site, install additional manufacturing equipment, and draw on Han’s Laser investments in synthetic quartz, optical preforms, and supply-chain capacity. The company positions HCF as a technology for optical communications, data center interconnect, cloud computing, high-performance computing, and high-power laser applications. Coractive also plans to supply specialty fibers to customers across North America, Europe, and other international markets.

“For 27 years, Coractive has been firmly established in Québec as a Canadian company specializing in optical fibers. We will continue to rigorously comply with the laws, regulatory requirements, compliance standards, and export controls applicable in Canada and internationally, while helping to strengthen the global competitiveness of the St. Lawrence River’s ‘Optics-Photonics Valley,’” said Lixian Wang, Vice-President of Research, Development, and Production at Coractive.
🌐 Analysis: Coractive’s expansion reflects growing industry investment in optical transmission technologies that could address latency, loss, power consumption, and scaling constraints as AI clusters and data center interconnect networks move toward higher capacities. Hollow-core fiber remains an emerging technology relative to conventional solid-core fiber, but Microsoft’s acquisition of Lumenisity and continuing HCF development programs elsewhere in the optical ecosystem show increasing strategic interest in moving the technology from research and specialized deployments toward commercial-scale manufacturing.
