Background and context from public sources — not the original article. 9 sources cited.

•JCET announced a major breakthrough in CPO technology on January 21, 2026, positioning it as an early leader alongside UMC's 22nm process for silicon photonics[1].
•NVIDIA plans to launch a CPO-based optical interconnect platform in 2026 supporting Ethernet and InfiniBand, reducing power from 30W to 9W per 1.6T module[4].
•Avicena is developing massively parallel LED-based optical interconnects as a low-power alternative for short-reach connections beyond copper limits[3].

•CPO integrates optical engines directly adjacent to ASICs, shortening electrical traces to millimeters, eliminating DSPs, and using shorter-reach SerDes for sub-pJ/bit efficiency[2][5].
•Reference designs feature ethernet switch ASICs with 16 light engine tiles, 1,152 fibers (128 laser, 1,024 data), and external laser modules at faceplate for cooling[2].
•Mikros Technologies’ MikroMatrix™ cold plate uses microchannel arrays for superior heat dissipation in high-density CPO racks[2].
•µLEDs enable robust photonic interconnects, operating at high currents and temperatures >100°C, suitable for AI data center servers[9].

CPO deployments will exceed 10 million 3.2T ports by 2029

Industry analyses project exponential growth driven by maturing platforms and AI bandwidth demands[5].

Full CPO transition cuts transceiver power by 84% versus DSP optics

CPO eliminates DSPs and long SerDes while adding optical engines, netting major savings in AI server power budgets[6].
