These devices are critical for enabling ultra-high bandwidth communication and supporting the expansion of 800G and 1. A liquid-cooled optical transceiver integrates cooling technologies such as cold plates or microchannels directly into its design. With the rapid development of 400G, 800G, and even 1. 6T optical modules, the power consumption of individual modules continues to rise, making traditional air cooling methods insufficient to meet the heat dissipation demands of high-density data centers and AI clusters. An ultra-compact, palm-sized AI productivity tool designed to handle inference for 200B parameter models and complex AI development right from your desktop. Zhejiang University First Hospital. The next key development is 800G, and the industry is already gearing up to deploy this next generation of client optics in hyperscale data centers. Developments in three distinct areas are needed for 800G deployment: optical modules and direct attach copper (DAC) cables, switch ASICs, and 800GE. ToneCooling provides custom-designed 800G optical module liquid cooling plates, engineered for hyperscale data centers, switch OEMs, and optical module manufacturers seeking stable, scalable, and production-ready thermal solutions. It is used to link the Quantum-X800 QM3x00 switches using Twin-port OSFP 2x800Gb/s transceivers to the dual 800Gb/s ConnectX-8 mezzanine card in liquid cooled system and ConnectX-8 PCIE.
