Dell'Oro Group: AI Back-End Network Switch Sales Surpass Front-End Networks
Dell'Oro Group reports that in 2Q 2026, AI back-end network switch sales surpassed front-end sales for the first time. Ethernet led in back-end networks, with Celestica, NVIDIA, Arista, and Cisco as top vendors. 800 Gbps switches dominated shipments, and 1.6 Tbps sampling began. The shift has significant implications for vendor positioning and market share, with supply constraints expected to persist.
