Broadcom unveils next‑gen CPO
Broadcom revealed its third‑generation co‑packaged optics (CPO) platform for 200G/400G connectivity — a clear signal that data‑center interconnect is accelerating to support AI workloads. Higher bandwidth, lower latency fabrics like this will reshape server and interconnect choices for AI clusters and service providers. (ico-optics.org)
Broadcom announced its third‑generation 200G‑per‑lane co‑packaged optics (CPO) product line in a company press release dated May 15, 2025. (broadcom.com) The firm said its second‑generation Tomahawk‑5 “Bailly” CPO reached volume production and credited validated improvements in OSAT processes, thermal designs, handling procedures, fiber routing and overall yield during scale‑up. (broadcom.com) The CPO roadmap is embodied in the Tomahawk‑6 “Davisson” CPO switch, which Broadcom and reporting outlets describe as a 102.4 Tb/s part operating at 200 Gbps per channel and doubling bandwidth versus the prior generation. (storagereview.com) Broadcom and independent coverage attribute the Davisson power gains to heterogeneous integration with TSMC’s Compact Universal Photonic Engine (COUPE) and advanced substrate‑level multi‑chip packaging, claiming roughly a 70% reduction in optical interconnect power compared with traditional pluggables. (storagereview.com) The company highlighted partner validation, pointing to a reported one‑million cumulative 400G‑equivalent port device hours test at Meta that Broadcom says ran without a single link flap as production‑readiness evidence. (sdxcentral.com) Broadcom reiterated active development of a fourth‑generation 400G‑per‑lane CPO while pushing interoperability and an expanding partner list to enable scale‑out and scale‑up AI fabrics across hyperscalers and system vendors.
