NVIDIA/Mellanox MMS4X00-NS-FLT Compatible 800GBASE-DR8 (2xDR4) Twin-port OSFP RHS/Flat Top PAM4 1310nm 100m Dual MPO-12/APC DDM SMF InfiniBand NDR Optical Transceiver Module for Liquid-cooled and DGX H100 Cedar7 Systems

One reason we chose this model was product availability. Other suppliers had much longer lead times, while these modules were ready to ship when we needed them. That helped us avoid delays during a time-sensitive deployment.

I checked the DOM information after installation, and all readings looked healthy. The module performs consistently under heavy traffic. So far, it has met all of our expectations.

This module has performed well in a high-density rack with continuous traffic. Heat has been well managed, and we haven't experienced link drops or compatibility problems. Overall, it's been a dependable choice for our deployment.

We've been running this module continuously for over a month, and the performance has remained consistent throughout. No unexpected alarms, retransmissions, or interruptions have been observed, which is exactly what we expect from production hardware.

Flat-top version works great in our liquid setup. Cheap, reliable, and I'll be back for sure.

We tested this module in a high-utilization environment where traffic levels fluctuate significantly throughout the day. The optical measurements remained consistent, and power consumption stayed within the expected range. The module handled the workload without drawing attention to itself, which is exactly what we wanted.

We selected the RHS version for a high-density deployment where heat management was an important consideration. The module worked smoothly after installation, and the connection remained stable during continuous operation. The design feels suitable for newer data center environments with demanding workloads.

We tested them with several hundred meters of single-mode fiber and achieved stable connectivity immediately. One thing I appreciated was how cool they operated even under sustained traffic loads. Would purchase again for future projects.

The packaging was good; the modules were securely fixed, and there were no cosmetic issues caused during shipping. Installation was also smooth, with insertion and removal going very easily. They have been working perfectly ever since.

We are particularly satisfied with the delivery speed; the order was shipped quickly after confirmation, without affecting the planned launch. The module passed testing on the first attempt upon arrival at the site, without any compatibility or quality issues.
