What it means
Linear pluggable optics (LPO) is a simpler, lower-power take on the optical transceiver: it strips out the digital signal processor (DSP) that normally cleans up the signal inside a module, relying instead on the switch chip's own electronics to drive the optics directly. Removing that chip cuts power and cost and reduces latency, while keeping the familiar pluggable form factor so it slots into existing systems with far less disruption than co-packaged optics. In the AI supply chain LPO sits at the networking layer as one answer to the optics power problem that worsens with every jump in data rate. It is a less radical alternative path to optics power savings — attractive because it preserves today's serviceable, multi-vendor pluggable model rather than fusing the optics onto the switch itself.
Why it matters to investors
LPO matters as the incremental rival to CPO: if it delivers enough of the power savings without re-architecting systems, it favors established transceiver and component makers over full co-packaged integration. The DSP and analog-component suppliers are the ones whose content shifts most as designs change.
