400G DAC is a direct high-speed cable used within data centers that supports a data transfer rate of 400GB per second.

400G DAC is currently the mainstream and widely deployed high-speed interconnection solution within ultra large scale data centers and AI computing clusters.

400G DAC is a cost-effective physical cable used for very short-reach connections (typically ≤3 meters). It directly links equipment such as servers and switches, serving as the backbone for internal data center interconnectivity.

400G DACTechnical Core
It features a passive design requiring no external power and utilizes PAM4 signal modulation. Employing common form factors like QSFP-DD and OSFP, it achieves a 400Gbps data rate through 8 channels.

400G DAC Core Advantages
Its primary benefits are extremely low cost and minimal power consumption (<0.1w), coupled="" with="" ultra-low="" latency.="">

400G DAC Application Scenarios

It is primarily used for interconnecting servers and switches or between switches within data center racks. In AI clusters, it is also extensively deployed for connections between GPUs and switches.
