Arista Networks announced a multi-source agreement for XPO, a new liquid-cooled pluggable optics module designed for AI data center networking.
The XPO module delivers 12.8 Tbps capacity per unit and supports rack densities of up to 204.8 Tbps per open compute rack unit, about four times higher than current 1600G-OSFP optics. The design includes an integrated cold plate capable of cooling up to 400 watts per module, enabling higher performance in AI workloads that require liquid-cooled infrastructure.
The module supports multiple optical standards including DR, FR, LR, SR and ZR/ZR+, along with next-generation interface architectures such as linear, half-retimed and fully-retimed designs. It is intended for AI networking environments including scale-up, scale-out and metro-reach data center fabrics.
Arista said the XPO specification will be demonstrated at the Optical Fiber Communication Conference (OFC) 2026 in Los Angeles with support from multiple optical module suppliers. Industry participants including Microsoft and market research firm Dell’Oro Group said the technology could help support the growing bandwidth demands of large AI clusters.
