Context Before
Some of Nvidia’s CPO SKUs—such as the SN6800 and Q3450—contain such a fiber shuffle within the switch box, with each optical engine fanning out to different logical ports. They therefore deliver higher aggregate bandwidth—409.6T and

115.2T respectively—than is possible with a switch box based on a single Switch ASIC.
Context After
For the SN6800 CPO switch, even though the bandwidth engine responsible for converting electrical to optical signals scales from 1.6T to 3.2T or 2x compared to the SN6600 switch, each 3.2T OE within the SN6800 switch box is split into four 800G logical ports that fan out within the box itself and exit the front panel through fiber connectors. This allows a single 1.6T GPU to fan out to two independent switch planes.
② Atomic Claim
另一個對應數值為 115.2T；這些 aggregate bandwidth 高於單一 Switch ASIC switch box 所能提供的水準。
