NVIDIA/Mellanox MMA4Z00-NS-FLT Compatible Broadcom DSP & Broadcom VCSEL 800G 2xVR4/VR8 Optical Transceiver Module for ConnectX-8 C8180 SuperNIC (Twin-port OSFP, 850nm, 50m, Two MPO-12/APC, DOM, for MMF, Flat Top)
NADDOD NVIDIA/Mellanox MMA4Z00-NS-FLT compatible OSFP-800G-2VR4F optical transceiver is designed for 800Gb/s Ethernet interconnects, using a twin-port OSFP architecture to support 2×400Gb/s VR4/VR8 multimode transmission over an 8-channel parallel optical interface. The module operates via two MPO-12/APC connectors, with each connector carrying four optical lanes, and uses 100G-PAM4 modulation to enable short-reach transmission of up to 50 meters over multimode fiber. Built-in Broadcom DSP & Broadcom VCSEL, it is compatible with NVIDIA ConnectX-8 C8180 SuperNIC, ensuring reliable, high-speed data transmission in demanding deployments.
By adopting a parallel multimode VR4/VR8 design, the OSFP-800G-2VR4F enables high port density and efficient short-reach connectivity within 800G switching systems. Finned-top OSFP shells are supported to meet the additional cooling requirements of 800G OSFP switches, while a flat-top variant is available for ConnectX-8 system links, providing deployment flexibility across different platform designs.
The OSFP-800G-2VR4F 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-2VR4F reduces optical module count by 20% compared with the C8240 using Q112-400G-VR4 solution. This delivers the following three key advantages.
