“While the surge in Ethernet switch sales was primarily fueled by accelerated adoption in AI back-end networks, front-end network sales were also strong, driven by the additional capacity needed to support the expanding back-end,” said Sameh Boujelbene, Vice President at Dell'Oro Group. “Vendors with a higher percentage of sales share of sales driven by back-end networks outperformed the overall market and gained significant share during the quarter,” added Boujelbene.
Additional highlights from the 3Q 2025 Data Center Switch Front-end and Back-end Reports:
— Front-end networks continue to drive well in excess of half of overall Ethernet data center switch sales.
— 100/200/400 Gbps comprised more than two thirds of the data center switch sales in front-end networks, while most 800 Gbps shipments are still destined predominantly for back-end networks.
— Sales momentum during quarter was broad-based across Cloud Service Providers and Large Enterprises.
