NVIDIA/Mellanox Compatible 800G 2xDR4/DR8 Optical Transceiver Module for ConnectX-8 C8180 SuperNIC (Twin-port OSFP, 1310nm, 500m, Two MPO-12/APC, DOM, for SMF, Flat Top)
NADDOD OSFP-800G-2xDR4F Optical Transceiver Module is an Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, 2xDR4/DR8 single mode, parallel, 8-channel transceiver using two, 4-channel MPO-12/APC optical connectors at 400Gb /s each. The parallel single mode, data center reach 8-channel (2xDR4/DR8) design uses 100G-PAM4 modulation and has a maximum fiber reach of 500-meters using 8 single mode 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-2DR4F 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-2DR4F reduces optical module count by 20% compared with the C8240 using Q112-400G-DR4 solution. This delivers the following three key advantages.
