NVIDIA's New 400G QSFP112 Optic Reaches 500m on Single-Mode Fiber
ServeTheHome's quick look details NVIDIA's MMS1X00-N5400, a 1310nm QSFP112 module built for 400Gbps links up to 500 meters.
ServeTheHome has published a quick look at NVIDIA's MMS1X00-N5400, a QSFP112 optical module that carries 400Gbps over a single 1310nm wavelength. The module is built for reach of up to 500 meters, positioning it for short-reach interconnects between switches, servers, or storage systems within a data center or campus environment.
The write-up focuses on the physical and optical characteristics rather than performance testing. Because it is a quick look, ServeTheHome does not compare the module against competing optics or provide power consumption figures. The key takeaway is that NVIDIA is shipping a 1310nm QSFP112 option for 400Gbps links at the 500m distance class, which is a common range for breakout and spine-leaf connections.
No other sources were provided, so there is no independent verification or contrasting viewpoint. The information is limited to what ServeTheHome observed in its hands-on preview.
