Corning Incorporated announced on May 13, 2025, a collaboration with Broadcom Inc. on a co-packaged optics (CPO) infrastructure designed to significantly increase processing capacity within data centers. Corning will supply cutting-edge optical components for Broadcom’s Bailly CPO system.
The Bailly CPO system is recognized as the industry’s first CPO-based 51.2 terabit per second (TBps) Ethernet switch. This combination is expected to deliver substantial improvements in optical interconnection density and power savings, making it ideal for large-scale artificial intelligence (AI) clusters.
Broadcom’s Bailly CPO system integrates eight silicon photonics-based, 6.4 TBps optical engines, which are co-packaged with Broadcom’s StrataXGS® Tomahawk®5 Ethernet switch chip. Corning is a qualified supplier of the necessary optical infrastructure, including fiber harnesses, connectors for front-plate and external laser modules, and fiber array units, ensuring high precision and reliability for these advanced AI deployments.
