Evidence

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

② Atomic Claim

在 SN6800 CPO switch 中，負責 electrical-to-optical conversion 的 bandwidth engine 相較 SN6600 switch，從 1.6T 提升至 3.2T、增加 2 倍；但 SN6800 switch box 內每個 3.2T OE 都會拆成 4 個 800G logical ports，並由 fiber connectors 從 front panel 輸出。
