Corning and Broadcom Team on Co-Packaged Optical Infrastructure
Corning Inc. has collaborated with Broadcom Inc. on a co-packaged optics (CPO) infrastructure that will significantly increase processing capacity within data centers, according to Corning. Per the partnership, Corning will supply optical components for Broadcom’s Bailly, a CPO-based 51.2 Tbps ethernet switch.
Broadcom’s Bailly CPO system incorporates eight silicon photonics-based, 6.4 TBps optical engines that are co-packaged with Broadcom’s StrataXGS Tomahawk5 ethernet switch chip. Corning is now a qualified supplier of the optical infrastructure necessary to bring fibers to these optical engines. The fiber harnesses that make up this optical infrastructure include connectors for the front-plate and external laser modules, single mode and polarization maintaining fibers, and fiber array units that connect the fibers to the optical engines with a high degree of precision and reliability.
CPO technology is expected to address the growing demands from AI workloads on networking and processing bandwidth, density, and power efficiency by placing optics and electronics closer together in a processing system. The technology enables higher speeds and densities while improving overall power efficiency in data centers.
