Technical detail

Construction and application notes for OSFP-800G-2SR4F

Review connector, construction, routing and handling details that apply to the selected family and exact SKU.

Interface and construction

The OSFP-800G-2SR4F module is tightly integrated with the C8180 SuperNIC’s multi-plane architecture, delivering key advantages in large-scale computing clusters. By distributing traffic across multiple planes, it maximizes bandwidth, enables smoother load balancing, and ensures consistently low latency. Each plane is isolated and inherently redundant, so a single path failure does not impact service continuity, enhancing overall reliability. With higher resource utilization and fewer congestion points, the ConnectX-8 architecture enables faster scaling and a more efficient, stable, and resilient network experience.

Application and routing

In ConnectX-8 NIC and Spectrum-4 switch AI cluster architectures, the C8180 paired with OSFP-800G-2SR4F reduces optical module count by 20% compared with the C8240 using Q112-400G-SR4 solution. This delivers the following three key advantages.
