Spectrum-6 SN6000 switch models
| Model | Ports | Capacity | Form factor |
|---|---|---|---|
| SN6810-LD | 128x MMC-12 CPO | 102.4 Tb/s | 2U, single ASIC |
| SN6800-LD | 512x MMC-12 CPO | 409.6 Tb/s (4x 102.4) | 5U, 4-ASIC |
| SN6600-LD | 64x OSFP 2x800G | 102.4 Tb/s | 2U, pluggable optics |
Use Case
SN6810-LD is specified for AI scale-out racks that have outgrown pluggable optics on power and reliability grounds: co-packaged silicon photonics removes the DSP-consuming pluggable modules from the front panel, cutting per-port power and creating a single-mode fibre fabric at 800 Gb/s per MMC-12 port. The 48 VDC busbar and UQD8 liquid loop let it drop straight into a high-density OCP rack alongside GPU nodes.
