This document defines the technical specifications for a 3.2 Tb/s Co-packaged Optical (CPO) transceiver module, including mechanically compatible Copper Cable Attach modules, see
The maturity of 448G SerDes will directly usher in the era of 3.2T optical modules. Doubling Port Density: By utilizing eight 448G lanes, a single module (in a form factor like OSFP) can achieve
CPO pushes interconnect performance to its limits through co-packaged integration, forming a critical foundation for future 1.6T and beyond high-speed interconnects. Each architecture
For example, a CPO design with eight 6.4Tb/s optical modules (using 400GBASE-FR4) would require ELS''s with 32 fibers, with four fibers routed to each optical module.
In traditional architectures, electrical signals require long PCB traces to reach the optical module, leading to insertion loss and crosstalk issues, and
A deep dive into Nvidia''s $4B optical networking strategy and how co‑packaged optics (CPO) will reshape AI factories, data centers, and high‑speed networking.

Co-packaged optics (CPO) is a disruptive approach to increasing the interconnecting bandwidth density and energy efficiency by dramatically
The copper that enables this has been hitting physical limits in different ways: signal integrity collapses, power consumption from copper traces eats a third of the switch''s energy, and
AI and hyperscale environments demand massive bandwidth, lower latency, and improved power efficiency—limits that traditional copper and pluggable optics
A failure in an optical engine might require replacing an entire CPO switch line card or server board rather than just swapping a pluggable module.
