What advantages do CPO switches such as the SN6800 deliver for Neoclouds like Coreweave and Lambda when it comes to large-scale cluster deployments?

Evidence

If we compare the power consumption of one 800G DR4 optical transceiver (16-17W) to the power required by optical engines (OEs) and external light source (ELS) modules to delivery an equivalent 800G of bandwidth in the scale-out network, we see an average ~70% reduction in power used for optical transceivers

② Atomic Claim

把單顆 800G DR4 optical transceiver 的 16–17W 功耗,與在 scale-out network 中用 optical engines(OE)及 external light source(ELS)modules 提供等效 800G bandwidth 的功耗相比,optical transceivers 相關 power 平均可降低約 70%。
