Technical detail
Review connector, construction, routing and handling details that apply to the selected family and exact SKU.
As XDR networks scale in port density and bandwidth, power consumption, cooling performance, and link stability become critical challenges. Compared with common 5nm DSP-based solutions, 3nm DSP-based 1.6T transceiver delivers lower power consumption, more stable links, and better heat dissipation in high-density scenarios—enabling long-term full-load operation of large-scale GPU clusters, while cutting port failure rates and reducing operational costs.

In large-scale AI clusters, XDR networking based on this 1.6T transceiver delivers measurable gains over NDR architectures. By reducing rack count, simplifying cabling, and improving space utilization, this solution increases compute density while enabling flexible future cluster expansion.

When paired with server-side 800G transceivers, they enable stable, high-speed interconnects between switches and NVIDIA DGX B300, GB300, and OEM HGX B200 servers.
