Optical interconnect is moving closer to the compute engine

The path from LPO to CPO is a power-efficiency story about shortening electrical paths as 1.6T links make DSP overhead untenable

Optical interconnect is moving closer to the compute engine. From FRO and TRO to LPO, LPO with CPC, and ultimately CPO, the direction is clear: reduce electrical signal distance, remove unnecessary DSP overhead, and improve power efficienc
