The NVIDIA MMA4Z00-NS is an 800Gb/s OSFP optical transceiver from the Mellanox product line, built as an SR8 multimode parallel module operating at an 850 nm wavelength over links of up to 50 m. The record lists 15 W power dissipation from a 3.3 V supply and an operating range of 0°C to 70°C, with tray packaging of 50 units. An SR8 module runs eight parallel lanes over multimode fibre, trading reach for low cost per bit on short in-rack and adjacent-rack links.

800G SR8 OSFP transceivers connect switches, network adapters and GPU servers across short multimode runs inside AI training clusters and high-performance computing fabrics, where hundreds of links sit within a single row. The 50 m reach covers top-of-rack to leaf and leaf to spine connections in the same hall at lower cost and power than single-mode optics. Data centre network architects and hyperscale operators buy these in volume when building out Infini Band and Ethernet fabrics for accelerated computing.
