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

As discussed in our recent deep dive article on co-packaged optics, the first reason is that a significant amount of power can be saved by eliminating most of the transceiver content. 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. Taking a step back, this would translate to 10% in savings for the total networking equipment power consumption in a 3-Layer HGX Rubin NVL8 cluster. This reduction in networking equipment power consumption is however relatively insignificant and amounts to only ~1% of total cluster power consumption because the server’s power budget dominates the equation.
