NVIDIA/Mellanox Compatible 800G 2xSR4/SR8 Optical Transceiver Module for ConnectX-8 C8180 SuperNIC (Twin-port OSFP, 850nm, 100m, Two MPO-12/APC, DOM, for MMF, Flat Top)
NADDOD OSFP-800G-2SR4F is an Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, 2xSR4/SR8 multimode, parallel, 8-channel transceiver using two, 4-channel MPO-12/APC optical connectors at 400Gb/s each. The parallel multimode, short reach 8-channel (2xSR4/SR8) uses 100G-PAM4 modulation and has a maximum fiber reach of 100-meters using 8 multimode fibers. The 800G OSFP switches require finned-top OSFP shells for extra transceiver cooling. A flat-top version offered for ConnectX-8 systems links.
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.
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.
