| Model | Optics | Capacity | Height |
|---|---|---|---|
| SN6600-LD | 64x OSFP pluggable | 102.4 Tb/s | 2U |
| SN6810-LD | 128x MMC-12 CPO | 102.4 Tb/s | 2U |
| SN6800-LD | 512x MMC-12 CPO | 409.6 Tb/s | 5U |
Use Case
SN6600-LD is the pragmatic Spectrum-6 deployment: same 102.4 Tb/s capacity and same Spectrum-X congestion control as the co-packaged SN6810-LD, but with 64 conventional OSFP cages so optics can be sourced, swapped and re-rates on the normal pluggable cycle. That matters in clusters where the fibre plant is already built around OSFP and where field replacement of a single transceiver is preferred over a chassis-level optical repair.
