Terry Little Sr. Development Engineering Manager Foxconn Interconnect Technology XPO (eXtra Dense Pluggable Optics): Fast-forward to 448 Gbps

p13

XPO (eXtra-dense Pluggable Optics) Introduction Today, we are proud to introduce our XPO (eXtra-dense Pluggable Optics) platform—a fully integrated, high-density “pluggable” connectivity architecture. We will discuss a scalable path forward from today’s 224 Gbps solutions, to the next-generation 448 Gbps AI and high- performance computing systems. I would like to acknowledge the leadership and vision of Andy Bechtolsheim, Co-founder and Chief Architect of Arista Networks, and the contributions of the XPO MSA member companies in advancing the next generation of high-density optical interconnect technology. Key highlights include: • High-density “Card-edge” connector for next-generation AI infrastructure, thus keeping the same existing XPO connector form factor. • Builds upon the proven 224 Gbps architecture to provide a scalable path to 448 Gbs.

Fast-forward to 448 Gbps XPO

p15

XPO “Fast-forward” to 448 Gbps Traditional 224G “Cantilever Beam” Contact Geometry The New 448G XPO system connector Objectives: The mechanical objective is to maintain the same XPO “Card-Edge” Form Factor. (0.56mm pitch) The electrical objective is to minimize undesirable stub effects at high frequencies. High-speed interfaces are sensitive to: •Stub length •Impedance discontinuities •Reflection-induced insertion loss • Traditional “Cantilever Beam Contact Geometry produces un-desirable IL “roll-off” at high frequency.

Assuming 448 Gb/s per electrical lane and ignoring FEC/encoding overhead: For a practical PAM6 implementation using 5 bits encoded across 2 PAM6 symbols—2.5 bits/symbol: • Symbol rate: 448 ÷ 2.5 = 179.2 GBd • Nyquist frequency: 179.2 ÷ 2 = 89.6 GHz So, the anticipated targets are approximately: • 448G PAM4: 112 GHz • 448G PAM6: 87–90 GHz • Actual baud rate and Nyquist frequency will be slightly higher when line-coding or FEC overhead is included.
