As demand for AI continues to grow, large-scale machine learning requires a vast network of GPU interconnections, driving a sharp increase in the optical fiber infrastructure needed for AI cluster back-end connectivity. However, traditional single-core optical fibers face limitations in both scalability and space efficiency.

Multi-core fiber (MCF), by integrating multiple cores within a single cladding, helps address the limitations of single core fibers- for example, a four-core MCF can replace four individual single-core fibers with a single fiber, effectively reducing the overall fiber volume in data centers and significantly improving space utilization. Traditional optical transceivers require an external fan-in/fan-out (FIFO) assembly device to connect to MCF fibers.

Hyper Photonix has developed an MCF compatible transceiver by integrating its proprietary Hyper Silicon^™ technology and successfully embedding the FIFO micro assembly directly into the optical transceiver module. This innovation eliminates the need for external FIFO devices, enabling direct MCF connectivity while enhancing network simplicity, space efficiency, and operational performance.

Looking ahead, Hyper Photonix is accelerating the development of next-generation 1.6T and 3.2T MCF optical transceivers, with plans for market release in 2025. These advancements will meet the growing optical connectivity demands of next-generation AI clusters while delivering cutting-edge optical communication solutions that enhance data center efficiency.
