Context Before

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.

Evidence

In fact, the SN6800 switch box consists of four ASICs, which is similar to the X800-Q3400 switch box.

Context After

As the per GPU bandwidth continues to scale to 3.2T, it is not hard to imagine a 4-plane network using SN6800 switches, where each 3.2T GPU is split four ways to connect to four different switch boxes at 800G per link.

② Atomic Claim

SN6800 switch box 由 4 顆 ASIC 組成，架構上與 X800-Q3400 switch box 類似。
