  • Arkansas' $1B BEAD broadband moment

    Arkansas' $1B BEAD broadband moment
    2025/10/31

    In late August, the Arkansas State Broadband Office released the state’s final proposal for the Broadband Equity, Access, and Deployment (BEAD) Program, officially opening the plan for public review and comment.

    According to the Arkansas State Broadband Office, the state's $1 billion BEAD program represents the largest public broadband investment in Arkansas history. The state's BEAD program garnered a strong response. Arkansas' State Broadband Office received 730 applications by 33 internet service providers (ISPs), and 23 providers selected for preliminary awards.

    During this Broadband Pulse podcast, we talked to Glen Howie, Director of the Arkansas State Broadband Office.

  • Ethernet Alliance on how 200G per lane will support AI and cloud computing innovations

    Ethernet Alliance on how 200G per lane will support AI and cloud computing innovations
    2025/10/24
    In this episode of the Broadband Pulse, we talked to the Ethernet Alliance about the upcoming High-Speed Networking (HSN) Plugfest that will be held from December 8-12, 2025, at Keysight Technologies in Santa Clara, CA. The Plugfest will feature interoperability testing for Ethernet devices ranging from 200GbE to 1.6TbE, covering various interconnects and transceivers. The event supports the transition to 200Gbps per lane, enabling breakthroughs in AI, cloud computing, and high-performance data centers. Besides the Plugfest, the Ethernet Alliance is also hosting the TEF 2025: Ethernet for AI. Taking a page from the TEF 2024: Ethernet in the Age of AI event, held in October 2024, the new event will take a deeper exploration into 400 Gbps electrical and optical signaling in response to the industry’s need to address the growing demands of AI workloads. During the podcast, we talked to two key members of the Ethernet Alliance: John D’Ambrosia, a Distinguished Engineer with the Datacom Standards Research team at Futurewei and Ethernet Alliance TEF Chair And Sam Johnson, HSN Subcommittee Chair for the Ethernet Alliance and manager of the Link Applications Engineering team within Intel’s Networking Solutions Group Here’s a timeline of the episode: Opening 0:03 Host introduces guests Broadband Pulse host Sean Buckley introduced John D’Ambrosia and Sam Johnson 1:08 Ethernet Alliance Plugfest event The details of the Ethernet Alliance’s High-Speed Networking (HSN) plugfest event in December at Keysight Technologies’ headquarters in Santa Clara, California. 5:16 200 Gbps per lane How 200G is the next building block speed in the evolution of Ethernet. 7:34 Seeing the potential in 1.6 Tbps The HSN interoperability tests will look at Ethernet devices ranging from 200GbE to 1.6TbE. 11:15 Coalescing around the Ethernet standard and the IEEE How vendors and the Ethernet industry are trying to find commonality. 12:14 TEF 2025: Ethernet For AI How the TEF 2025 for AI will address how to help the Ethernet industry address increased bandwidth, faster signaling, power delivery challenges, advanced packaging technologies, next-generation test equipment and methodologies, and new approaches to cooling. 15:05 AI networking based on 400Gbps signaling How the next generation of AI networking, based on 400 Gbps signaling, is likely to diverge significantly from today’s architectures. 19:14 Final Thoughts/Closing John D’Ambrosia and Sam Johnson give their final thoughts about the ongoing evolution of Ethernet. About our guests: John D’Ambrosia, a Distinguished Engineer with the Datacom Standards Research team at Futurewei and Ethernet Alliance TEF Chair John D’Ambrosia is a Distinguished Engineer with the Datacom Standards Research team at Futurewei Technologies, a U.S. subsidiary of Huawei. John has over 25 years of experience supporting standards development. John is currently the chair of the IEEE P802.3dj 200 Gbps, 400 Gbps, 800 Gb/s, and 1.6 Tbps Task Force. Previously, John chaired the IEEE 802.3 Task Forces that developed 40 GbE and 100 GbE, 200 and 400 GbE, and 800 GbE. Additionally, he chaired other IEEE 802.3 task forces, as well as the IEEE 802.3 New Ethernet Applications Ad hoc. John is also a member of the IEEE 802 LAN / MAN Standards Committee and is an IEEE Senior Member. In addition to his multiple roles in IEEE 802, John is one of the founders of the Ethernet Alliance and served as Chairman from 2011 to 2019. John served as an advisor to the European Photonics Industry Consortium from 2019 to 2022c. His previous work experience includes Dell, Force10 Networks, and Tyco Electronics. Sam Johnson, HSN Subcommittee Chair for the Ethernet Alliance and manager of the Link Applications Engineering team within Intel’s Networking Solutions Group Sam Johnson is an Engineering Manager with Intel Corporation, leading the Link Applications Engineering team within the Network and Edge Group. Sam started at Intel in 2010 with a focus on 10G Serial Ethernet debug and has built a career based on High Speed Serial Ethernet PHY and pluggable media behavior, configuration, and interoperability. He and his team work to define and develop the Ethernet hardware control infrastructure and to enable and support Intel customers' Ethernet solutions. Sam holds multiple patents related to Ethernet interoperability and is a co-chair of the High Speed Networking subcommittee within the Ethernet Alliance, with a focus on L1 protocol and interoperability testing. Outside of work, Sam enjoys spending time with his family, woodworking, and all forms of outdoor recreation.

  • Semtech’s Kimber on advancing Linear Pluggable Optics (LPO) standards

    Semtech’s Kimber on advancing Linear Pluggable Optics (LPO) standards
    2025/10/17

    As bandwidth demand accelerates and power consumption issues become more acute, the emergence of Linear Pluggable Optics (LPO) has become a welcome technology. LPO is a technology that creates low-power optical modules for ultra-short-reach data center connections by removing the complex DSP (Digital Signal Processor) chip from the module. This design reduces power consumption, cost, and latency, making it ideal for AI clusters and hyperscale data centers. Industry standards groups have focused on two main developments: electrical interface standards and testing and optical link performance and deployment. The Optical Internetworking Forum (OIF) is moving forward with electrical interface standards while the LPO Multi-Source Agreement (LPO MSA) is addressing optical link performance and deployment challenges. In this podcast, we talked with Mark Kimber, the senior principal product definition specialist for Semtech. Here’s a timeline of the episode:

    Opening

    0:05 Host introduces guests Broadband Pulse host Sean Buckley introduced Kimber to the program.

    0:38 LPO’s emergence Mark Kimber addresses emergence of LPO and Semtech’s role.

    1:54 The LPO Multi-Source Agreement (MSA) How the new LPO MSA is establishing a specification and a methodology to make LPO work.

    3:40 LPO standards efforts How the LPO MSA and the Optical Internetworking Forum (OIF) call for creating optical and electrical standards.

    4:56 Semtech’s direct edge portfolio Semtech’s LPO platforms can help data center providers accommodate AI’s new power, latency and size requirements.

    6:31 LPO plug and play operations Plug-and-play is key to help simplify large data center operations and management.

    11:04 OIF’s Common Management Interface Specification (CMIS) role CMIS manages the LPO module's diagnostic capabilities, including monitoring the optical and electrical interfaces. 11:35 200G per lane technology How LPO can save power at higher speeds like 200G per lane. 14:10 Final Thoughts/Closing Mark Kimber offers his final thoughts on LPO.

    About our guest Mark Kimber is the Principal Product Definition Specialist at Semtech Corporation. Mark received the BE (Elect) degree from the University of Queensland in 1984. Since then, he has worked on research and product development at GEC Hirst Research Centre, STC Laboratories, Bell Northern Research, Nortel, Bookham, Gennum and Semtech. Mark currently works on product definition for Semtech products and is a contributor to various standards groups.
