Panel II: Inside the Data Center

Tuesday, 08 June 14:15 – 15:45

Moderator: Hideki Isono, Fujitsu Optical Components, Japan

Panel Description:

Global Datacenter IP traffic, growing rapidly at a 26 percent year over year growth rate, is to become 4.8 Zettabytes in 2022, according to Cisco Visual Networking Index 2019. To meet this huge capacity demand, high speed network systems are being deployed with optics operating at 100Gbit/s and beyond. The IEEE802.3 has completed new Ethernet standards for rates up to 400Gbit/s (802.3bs/cd) in 2018 adopting 25GBaud PAM4 50Gbit/s optical modulation (8x50G). They have also recently introduced the 50GBaud PAM4 100Gbit/s optical modulation format as new Ethernet technology building blocks for 4x100G 400GE optical interfaces. As for electrical interfaces, 50Gbit/s per lane 400GE has already matured (8x50G) and 100Gbit/s per lane 400GE (4x100G) is being discussed. Along with these developments, new pluggable form factor MSAs such as QSFP-DD and OSFP have been commercialized and matured. As a result, maximum system board-level data throughputs have reached as high as 14.4Tbit/s, such as with 400G X 36 Transceivers. The next phase of the datacenter technology roadmap (beyond 400G) remains somewhat unclear. What kind of technologies we should choose and when such migration will occur? In 2019, new MSA such as 800G Pluggable MSA or QSFP-DD800 MSA was organized and solutions for 800G and/or 1.6T can be expected. If industry sticks to pluggable solutions, we will see parallel solutions such as dual- or quad- 400G pluggable modules or will pursue 200G per lane optical solutions. Industry also start considering to adopt the cost effective digital coherent solutions even for intra data center, in order to cover the reach where IM-DD are not able to achieve. Some solutions will require drastic improvements in integration technologies and improvements in CMOS processes below 7nm to restrain increases in power consumption density. An alternative future direction would be on-board optics or co-packaging, which may need new technology breakthroughs and more time to mature. This panel will introduce the views of several industry leaders in this area and evoke discussion among panelists and the floor.

Robert Blum, Intel, USA
Presentation Title: Integrated Silicon Photonics for High-volume Data Center Applications

Abstract: The rapid growth in data center traffic has been the key driver for the increased performance of networking equipment, such as Ethernet switches and optical pluggable transceivers. But bandwidth scalability challenges around density, cost, and power will require much tighter integration of optics and networking silicon in the near future. We will discuss how silicon photonics combined with advanced packaging approaches can enable higher density, reduced power per bit, and ultimately the continued scalability of network bandwidth and performance.

Brad Booth, Microsoft, USA
Presentation Title: Network Diversity

Abstract: Machine learning, artificial intelligence, front end network, backend network, edge, core, DCI, etc. Equipment and transceiver manufacturers look to find commonality to develop products for market volume, but the list is long on what drives differentiation. Is there commonality to be found or will diversity persist?

Jeffery Maki, Juniper Networks, USA
Presentation Title: 800G and the Crossroad to Optic Digitalization: The Path to Scaling and Efficiency

Abstract: Routing and switching system build-out is occurring along two major lines of using a 4-lane or an 8-lane module. Co-packaged optics and near package optics with their own module form factors, yet to be decided, pose additional lines of system build-out. Complexity of the optical transceivers for any of these cases increased significantly from adoption of PAM-4 electrical and optical modulation. This complexity poses challenges for interoperability between the host ASIC and the module. The presenter will review this complexity and how the industry is uniformly managing it by using the Common Management Interface Specification (CMIS).
