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

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.

These have been running continuously in our lab for months without a single issue. Reliability has been better than expected.

Byggekvaliteten på disse optikkene er virkelig knallbra, og de funker like godt som OEM-greiene til en brøkdel av prisen. Eneste lille minuset var at jeg fikk noen betalingsfeil. Men ærlig talt, når jeg ser hvor bra de er og pengene vi sparte, så er det fortsatt en kjempeseier. Blir nok å handle igjen!
