The passage around this formula
…sources, the photonic-PIC yield loss, the switch die itself — divided across a single module looks catastrophic; divided across sixteen thousand modules in a hyperscale fleet looks close to free. That is precisely why belongs in the model as a scale-dependent term rather than a single constant: the same fabric can fail the copper baseline at pilot volumes and clear it easily at fleet volumes, and a headline efficiency number has every incentive to quote whichever scale flatters it without ever…
