Cisco Optics Podcast Ep65: The Tradeoffs Shaping the Race to 3.2T - John Calvin, Part 2 of 8

In the pluggable optics industry every next generation is led by countless presentations and proposals at standards bodies meetings along with lots of lab development and testing behind the scenes. Right now the industry has its sights set on 3.2 terabit transceivers with 400 Gb per electrical lane. All those meetings and all that testing are happening as we speak. Today I am joined by John Calvin, Strategic Planner and Datacom Technology Lead at Keysight. John has been bridging the measurement science gaps of emerging telecom and datacom development efforts for 20 years. He has chaired multiple physical layer interoperability working groups and is currently serving as a contributing member to IEEE 802.3, OIF-CEI, InfiniBand, and PCIe development efforts. John holds a BSEE from Washington State University, and his graduate level studies are in signal processing from Stanford University. In Episode 65 we continue our conversation with John. We get into the tradeoffs between IEEE standards, MSAs, interoperability, and the race toward 3.2-terabit Ethernet. John has very generously made himself available for your follow-up questions. You can find him at IEEE 802.3 technical forums or you can email him at [email protected]. Please follow the Cisco Podcast Network on Spotify or Apple Podcasts!

In this episode Robin Olds interviews Tom Footitt, Cisco Senior Director of Product Management for Crosswork Assurance, about how AI — especially agentic systems and faster LLMs — is changing network traffic patterns and why observability and assurance are critical. They discuss new KPIs like time-to-first-token and inter-token latency, passive behavioral analysis of encrypted traffic, predictive AIOps, and the importance of security, sovereignty, and performance for service providers offering AI services.

Our best friend (and career coach) Sammy Brenner is back with a new role, a new language to learn, and approximately six months before she’s ready to teach any of it to us (her words). Sammy and Kat share what it’s really like to start over in a new part of the business: drinking from the fire hose, rebuilding trust, and reminding yourself that you were hired for a reason, even when doubts creep in. They also get into how to know when it’s time for a change, why networking should start long before you need a new job, and how to advocate for yourself without feeling like a professional kiss-up. Sammy shares her best advice for building genuine relationships, creating an “About Me” deck, and approaching your first few months with equal parts curiosity and blind optimism. Meanwhile, Ian bravely attempts to lighten the mood with a story about his Chrome tabs and learns no one cares.

This episode explores how AI agents, network sensors, and cloud-managed Meraki solutions are transforming workplaces across industries—from stadiums and events to critical infrastructure. Leaders share real-world use cases on security, hybrid work, real-time visibility, and practical deployments that balance automation with human oversight.

Across Cisco's partner ecosystem, AI adoption isn't new — it's already happening at scale. So how do partners turn that momentum into trusted, real-world outcomes for their customers?  In this episode of Scaling AI in the Enterprise, we bring together an all-star partner panel featuring Trace3, Worldwide Technology (WWT), and Presidio to tackle the real challenges of scaling AI: the shift from dashboards to semantic layers, the discipline of clean data and governance, the balance between automation and human judgment, and why adoption is as much about culture and trust as it is about technology.   Host: Emma Carpenter, SVP Recurring Revenue Acceleration, Cisco Customer Experience    Guests:   Josh Lindstrom, Sr. Director, Data and Analytics, Trace3   Surbhi Kaul, VP CX Product Management, Cisco Customer Experience     Kevin Corace, SVP Software and Services Lifecycle, Presidio    Laura Kuehner, VP Customer Experience, WWT    Learn more about Cisco Customer Experience; read our blogs and visit Cisco.com. 

Deal registration isn’t paperwork. It’s partnership—and a powerful lever for growth. In this episode of Shift Happens, Jeff Edwards is joined by Tim Coogan, Gary DePreta, and Raminder Mann, CEO of ANM, Cisco’s 2025 Security Partner of the Year, for a candid look at what happens when Cisco and partners stop competing with each other and start competing together. From a $10M+ opportunity closed in under two weeks to $25M in competitive takeouts, hear how registering early creates the trust, investment and shared focus needed to win—and unlock what comes next: adoption, expansion and renewal. Why listen? 🎯 See deal reg differently: It’s not about protecting a deal—it’s about creating a foundation for mutual investment and customer value. 💰 Hear the real-world impact: Get inside the deals where partnership helped turn stalled opportunities into wins and competitive takeouts into future growth. 🚀 Think beyond the PO: Discover why the biggest value may come after the deal, when Cisco and partners have the resources and trust to drive adoption, expansion and long-term success. Because when you sell together, you don’t just win the deal—you build what comes next. 🎧 Tune in to the latest episode and let’s make shift happen. #CiscoShiftHappensPodcast

This week is a true charcuterie board of an episode: a little career news, a little AI, and a surprisingly serious debate about crackers. Kat recaps her trip to San Francisco, shares some news about her new role, and explains why a tea leaf salad earned “best bite of the weekend.” Meanwhile, Ian reveals that he has very specific charcuterie standards and is now using Haiku almost exclusively because, apparently, he’s saving the world one AI prompt at a time. They also catch up on what they learned from Annie Hardy, get excited about Cisco’s new AI agents, and try to make sense of ChatGPT’s new iMessage integration. Is it genuinely helpful, or does letting AI write your texts feel like one step too far? No conclusions are reached, but everyone agrees that “it all stays on your device” sounds exactly like something we’ll revisit when the apology statement drops.
