Product questions & answers
Is this one 800G optical port?
It contains two 400G optical ports in one twin-port OSFP, each using an MPO-12/APC connection. It is not the single-port 4x200G XDR design.
Which fiber and reach are specified?
Single-mode, 1310 nm-class 2xDR4 links up to 500 m are specified. The published reach assumes the documented optical path including two patch panels.
Why select the -FLT version?
NVIDIA identifies -NM-FLT for DGX H100. Its finned-top sibling is documented for Quantum-2 and Spectrum-4 switch cages; the cooling variants must remain distinct.
Which protocols are documented?
The exact -FLT OPN is listed with NDR and aggregate 800GE in the current CX7/CX8/CX9 matrices; its two optical ports remain 400G each.
Is it safe to look into a connected optical port?
No. Never look directly into an energized optical port or connected fiber; its infrared light can be invisible.
Can DR4 and FR4 be directly linked?
No. DR4 uses parallel optical channels; FR4 multiplexes wavelengths onto a fiber pair. Match the optical format at both ends.
