Next Generation Optical Interfaces – An IEEE and Industry Update

Wednesday, 09 June 13:30 – 14:30

Session Description:

The IEEE panel on next gen optical interfaces will cover new developments happening in the industry and IEEE which include new low-cost 100 Gbps coherent spec, “400ZR+” spec, and new work that covers 800 GbE or co-packaging. This panel will show the latest results, drivers, customer needs, etc. on these topics with a high level / applications focus.

Moderator:

Mark Nowell, Cisco, Canada

Mark Nowell is a Cisco Fellow in Cisco’s Data Center Business Unit. His focus is on next generation interconnect technology innovation to meet Cisco's needs. Mark is also active within the industry standards and forums and has chaired multiple IEEE 802.3 Ethernet projects. He represents Cisco on various industry alliances and Consortium. Mark also chairs a number of industry MSA (Multi-source Agreement) groups focusing on next generation optical module form factors (QSFP-DD, QSFP-DD800) and optical interface signaling technology (100G Lambda MSA, 400G BiDi).

Presentation Title: Transceiver Implementation Perspective on Next-gen Client Optics

Abstract: More than two decades of evolution of client-side optical transceivers have given them some core characteristics – standardized interfaces, interoperability, high volume, and continuous improvements in cost efficiency and power efficiency. As the market prepares to move to “beyond 400G”, these transceivers will see yet another round of transformation in lane speed and bandwidth density. We will examine components, device technologies and link level considerations that will ensure the success of such transceivers in the market.

He has been an active contributor to optical standards development in IEEE. He holds a Master’s Degree in Electrical Engineering from Columbia University, New York.
 

Radha Nagarajan, Marvell, USA
Presentation Title: Next Generation Data Center Interconnects at 800G and Beyond 

Abstract: 400G data rates are well into deployment for both inter (16QAM, 400ZR) and intra (PAM4, DR4/FR4) data center applications. We explore the options for the next data rate at 800G and beyond. We focus on the technology, transmission format and relative merits of the various options that are being proposed in the industry. We explore the tradeoffs between the PAM4 and 16QAM transmission formats for these applications.

Dr. Radha Nagarajan is the CTO and SVP, Connectivity Business Unit at Marvell. Dr. Nagarajan brings more than 20 years of experience in the area of high-speed optical interconnects and design, development and commercialization of large-scale photonic integrated circuits. Dr. Nagarajan is a Fellow of the IEEE, OSA and IET (UK). In 2006, he shared the IEEE/LEOS Aron Kressel Award for his work on commercializing large-scale photonic integrated circuits. He has been awarded more than 195 US patents. He received his B.Eng. from the National University of Singapore, M.Eng. from the University of Tokyo, and Ph.D. from the UC, Santa Barbara.
 

Scott Schube, Intel, USA
Presentation Title: Next-Generation Bandwidth Scaling with Integrated Optics

Abstract: This talk will cover emerging technology and market trends and challenges as optical transceivers evolve to support the massive I/O bandwidths needed for scaling next-generation high-volume data center applications.  We will discuss different paths to scale optical link bandwidth to 800G, 1.6T, and beyond; industry standardization options; and new optics device and packaging technologies, focused particularly on integrated optics technologies such as silicon photonics.

Scott has worked in the optical communications component industry for 20 years in both technical and marketing roles.  As an engineer he developed Gigabit Ethernet transceivers for AMP Lytel and then at Tyco Subcom he designed high-performance receiver line cards for ultra-longhaul undersea communication.  Scott went on to a variety of marketing and management roles, from technical marketing to product management and strategic marketing, at Intel OPD and NeoPhotonics, as well as senior analyst at optics industry research firm LightCounting.  Currently Scott is senior director of strategic marketing and business development in Intel’s silicon photonics group, where he has helped grow the business from zero to one of the leading global optical transceiver suppliers.
 

Tom Williams, Acacia (now part of Cisco Systems)​, USA
Presentation Title: The Launch of 400G Coherent Pluggables and What Comes Next

Abstract: The industry has made a major investment in standardized 400G pluggable solutions over the last several years. These modules are shipping in multiple configurations and expected to ramp significantly over the second half of 2021. Network operators plan to use a mix of deployment models to leverage the power, performance, and operational benefits offered by these solutions. Topics to be explored include where these interoperable interfaces will be deployed, how will they impact the rest of the coherent market and where do we go from here?

Tom is responsible for global marketing and communications activities for Acacia, which is now part of Cisco Systems. Prior to Acacia, Tom spent 14 years at Optium and Finisar Corporations, where he held various management roles, including Director of Product Line Management for high speed (>100G) transmission products. Tom has also held positions at Lucent Technologies and Northrop Grumman Corporation. He has an MS in Electrical Engineering from Johns Hopkins University and BS degrees in Electrical Engineering and Physics from Widener University.
