LPO · Linear Pluggable Optics
Pluggable optics with the DSP removed so the host ASIC's SerDes drives the optic directly; it cuts module power sharply but makes you the owner of the entire electrical path and its interop risk.
Current numbers
14-17 W → 7-8.5 W800G optics power: DSP pluggable vs LPO; CPO under ~6 W
14–17 W → <6 Wper-800G optics power: DSP pluggable vs CPO (~5.4 W Bailly class); LPO ~7–8.5 W
