产品问答
How is the 1.6T link presented optically?
The exact ordering row specifies twin-port 2xFR4 with two duplex-LC single-mode interfaces, nominal 1310 nm-class wavelengths and reach up to 2 km.
How should IHS and RHS be chosen?
NVIDIA describes IHS for air-cooled Quantum-3 / Spectrum-6 switches and RHS for liquid-cooled variants. Confirm the actual switch configuration.
What power should be used for planning?
The current product specification lists 28 W maximum. An older deprecated parts-list snippet is not the governing source.
Is the per-port optical lane statement ready to publish?
No. The page contains conflicting channel/rate wording. This package keeps the confirmed 2xFR4 identity and electrical lane data while holding the inconsistent optical lane statement.
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.
