David Piehler

Distinguished Engineer, Dell Technologies

Abstract：The development Ethernet optical standards and extensions (such as co-packaged optics) has focused on (high radix switch)-to-(high radix switch) connectivity. An Ethernet adapter card (also called a network interface controller/card [NIC]) facilitates the connection from a top-of-rack switch to compute (server), storage or accelerator resources. The NIC physical environment is distinct from the switch environment with a different spectrum of benefits and opportunities for the use of lower-power dissipation, lower-cost and lower-latency linear pluggable optics.

Speaker Bio：David Piehler is a Distinguished Engineer at Dell Technologies' Infrastructure Systems Group where he focuses on high-speed optical fiber transmission between and within datacenters, and increasingly as part of AI/HPC cluster fabrics. Previous positions include Chief Scientist at NeoPhotonics (NPTN, acquired by Lumentum in 2022); Vice President, Broadband Access Networks R+D at Harmonic, Inc. (HLIT) and Entrepreneur-in-Residence at the Mayfield Fund, a venture capital firm. He received his Ph.D. in Physics from the University of California, Berkeley for experimental research in nonlinear optics.

Ryan Latchman

Vice President, High Performance Connectivity Product Marketing , MACOM

Abstract：With climbing PAM bit rates, optical links have been increasing the number of transistors (and therefore power consumption) used for interconnections between network elements. With Linear Drive, the optical industry has an opportunity to take a “Less Is More” approach to achieve a high performance optical link which enables lower power, lower cost, and minimum latency.  This presentation reviews how Linear Drive achieves “Less Is More” with supporting results along with industry progress.

Speaker Bio：Ryan Latchman holds a & Mgmt from McMaster University, an from the University of Toronto, and an MBA from the Rotman School of Management.  Mr. Latchman is currently VP, High-Performance Connectivity Product Marketing at MACOM Technology Solutions Inc. with a focus on physical layer components used in Datacom and Telecom applications.  Mr. Latchman has also contributed to industry standardization efforts in the IEEE, OIF, and Fibre Channel.

Jeff Hutchins

Director of Optical Technologies, CTO Office, RANOVUS

Abstract：There has been a lot of interest in non-retimed links sometimes referred to as “direct drive” or “linear drive” links.  This presentation discusses non-retimed links, their use cases, considerations for standardization, and suggests an approach to evaluate their performance and suitability for an application.

Speaker Bio：Jeff Hutchins works for RANOVUS as Director of Optical Technologies in the CTO’s office and has been active in multiple industry-based standards development activities spanning decades.  Most recently, he has been active in standardization of co-packaging.  He has previously worked for HP, iolon, Intel, CoreOptics , and Cisco.

Frank Chang

Chief Engineer and CTO, Source Photonics

Speaker Bio：Frank Chang is an expert in photonic IC technologies, optics transceivers, and optical networking. He is currently Source Photonics’ Chief Engineer for advanced and next-generation transceiver design. Previously he served as a senior Principal Engineer for Optics Interconnect within the CTO Optics Office at Inphi Corporation for over 5 years after over 12 years of service at Vitesse Semiconductors. In addition, he also held various project and management positions with Cisco/Pirelli, and JDS Uniphase, working on the design, development, and commercialization of fiber optics components. Frank recently published the industry first DCI book entitled “Datacenter Connectivity Technologies: Principles and Practice”. He is a frequent conference speaker, co-authored 100 plus regular journal and conference papers, and has served in ECOC and OFC technical committees for several years in a row. Frank was the president and now among the board and advisors at Photonic Society of Chinese-Americans (PSC-SC). He is the Industry Forum & Exhibition (IF&E) Chair for Globecom 2015 in San Diego, Globecom 2019 in Hawaii and now ICC 2024 in Denver with IEEE Communication Society. Frank is the Chair of Advanced Technology Working Group of IPEC (The International Photonics & Electronics Committee). Frank obtained his Ph.D degree in Optoelectronics from the Ecole Polytechnique, University of Montreal, Canada for his research thesis on ultrafast optical generation of 1550nm tunable solid-state lasers. Besides Frank is senior member of IEEE and OSA Fellow. 

Man Jiangwei

Director of Advanced Opto-Electronics Laboratory, HiSilicon

Abstract：The linear technology shows much benefit in power consumption, cost and latency. However, due to the lack of DSP/CDR, much work needs to be done to achieve optical interconnect in between transceivers from different vendors. In this presentation, we will have a discussion on the design, test and system adaptation for linear technology.

Speaker Bio：Dr. Man Jiangwei, director of Huawei's Advanced Opto-Electronics Laboratory, is responsible for researching advanced technologies of optical systems, optical modules, and chips, as well as optoelectronic standards and patents. Dr. Man has led his opto-electronics R&D team to make outstanding contributions to 25 Gbit/s, 50 Gbit/s, 100 Gbit/s, and 400 Gbit/s optical modules/chips, optical transmission system research, and standards research, and is committed to technical research and innovation in various optoelectronic services. Dr. Man obtained a bachelor degree from the School of Physical Sciences of Nankai University and a doctoral degree from the Institute of Semiconductors (IOS) of the Chinese Academy of Sciences (CAS).

Hacene Chaouch

Distinguished engineer, Arista

Abstract：In this presentation we will review the latest performance results of LPO technology using a 51T ages and potential improvements will be discussed for different use cases.
