Is On-Board Optics the Right Solution to Reduce Power Consumption of Data Center Networking Hardware?

Despite improved efficiencies, the power consumed by data center networking hardware is growing rapidly in proportion to increasing network capacity.  Networking is expected to contribute a significant fraction of the overall power budget when data center networks transition to 400G interfaces. New approaches are needed to further improve efficiency and reduce energy per bit. This workshop will explore the potential benefits of moving optics closer to the switch ASIC to eliminate power hungry SerDes, and thus reduce overall power consumption. The workshop will try to answer the questions: Can on-board optics provide a solution in the near term or do we need co-packaged optics to gain a significant benefit? What are the engineering and techno-economic tradeoffs? Is fully integrated optics still a dream or reality?

High Speed ≥ 100 Gb/s/lane Optical and Electrical Interconnect Workshop: Tuesday, 6 June at 3:45pm-5:45pm in the Mesa Ballroom

IEEE P802.3 standard and OIF are currently defining chip-to-module, chip-to-chip, and backplane signaling based on 50Gb/s/lane PAM4 signaling. IEEE P802.3 standards currently are defining single lamda 100 Gb/s optical links based on PAM4 signaling. The 50 Gb/s electrical IO allows doubling the BW of a 128 lane switch from 3.2 Tb to 6.4 TB and allow doubling the BW of a 256 lane switch from 6.4 Tb to 12.8 Tb. The switch IO bitrate has been doubling approximately every 3 years. Assuming the current trend continues, we will have switches based on 100 Gb/s/lane in 2019. Switches with native 100 Gb/s IO expect to offer seamless interface to pluggable optical modules or an OBO (on board optics), but supporting conventional backplane at 100 Gb/s may not be feasible and instead eco-system may need to convert to copper cable or optical backplanes. What are the key challenges to transition to 100 Gb/s electrical and optical ecosystems and is the industry investing enough for such a major transition that is expected to occur in next 3 years? What are the practical solutions beyond 100 Gb/s? Is the right solution 200 Gb/s with higher Baudrate, stronger FEC, and/or higher order modulation, or a co-packaged PIC with WDM to increase the IO BW?
