From the MD&A

"We are working with leading industry partners on Optical Engines and other components for 400G transceivers, which is the next generation of transceiver modules that are expected to be introduced into data centers in the coming months and years. We believe that the Optical Interposer platform is very relevant to markets beyond data communications, such as telecommunications, automotive LIDAR, and integration with Application Specific Integrated Circuits (ASICs), including switches and graphics generators.
