The Ethernet Alliance: Twenty Years of Community, Collaboration, and Innovation Part II: Beyond the Horizon

Looking back is one of the pleasures of celebrating an anniversary, and that holds true for the Ethernet Alliance’s 20th. But Ethernet has always been just as much about the road ahead as the road behind. That’s because every milestone in Ethernet’s history has really been the starting point for the next one. 

Charting the Future 

Throughout the Ethernet Alliance’s first twenty years, one thing has remained constant: Ethernet never stands still. Every time the industry solves one challenge, another lies just beyond the horizon. Supporting Ethernet has always meant doing more than celebrating where it has been; it means helping the industry prepare for where it’s going next. 

By the middle of the last decade, Ethernet was dealing with a good problem to have – it was everywhere, seemingly all at once. Every new speed opened the door to new applications, new markets, and new possibilities. What looked like Ethernet branching in a dozen different directions was really just a sign of its adaptability. But how do you navigate all those twists and turns? As it turns out, you need a roadmap. 

The Ethernet Roadmap was the Ethernet Alliance’s answer to that challenge. Introduced in 2015, it gave the industry something it had been missing: a way to see the bigger picture. Rather than focusing on a single speed,

market, or technology, it showed how they all fit together. And in doing so, the Roadmap made it clear that Ethernet’s future wasn’t one destination, but many. 

One of the things that I love about the Roadmap is that it reminds us to stop looking at Ethernet one speed or one market at a time – the enterprise, the data center, the service provider, the home, and now, AI. These aren’t competing paths; they’re all part of the same journey. Every new rate, application, deployment, and advance adds another chapter to Ethernet’s story. 

Like both Ethernet and the Ethernet Alliance, the Roadmap has never been content to stand still. Looking back through its earlier editions is a little like opening a time capsule. Technologies that once felt like tomorrow are now woven into our everyday lives. Yet somehow, tomorrow keeps finding new ways to surprise us. The 2026 Ethernet Roadmap is a reminder that Ethernet’s story is far from finished. And that’s exactly the way Ethernet likes it. 

Chasing the Impossible 

Of course, seeing the future is only half the fun. Someone still has to actually build it. And if there’s any one thing engineers have never been able to resist, it’s being told something can’t be done.  

That instinct to say, “Challenge accepted!” inspired one of the Ethernet Alliance’s most memorable traditions: Ethernet’s Holy Cup and Holy Grail. The Cup and Grail weren’t detours in Ethernet’s journey; they were fuel for it. Instead of waiting for the Next Big Thing to arrive, the Ethernet Alliance challenged the industry to go make it happen. 

The beauty of Ethernet’s Holy Cup and Holy Grail wasn’t simply that they set ambitious goals. It was that they dared engineers to see just how far they could push the technology. It wasn’t about building a slightly better version of yesterday’s Ethernet. It was about asking the industry, “What’s next?” and then seeing who was bold enough to answer

This is where the Ethernet Alliance does its best work. It wasn’t giving the industry a finish line; it was inviting everyone to help decide where that line should be. The Holy Cup asked engineers to find a way to achieve a single-lambda 100GbE QSFP28 optical solution within an equally demanding power envelope. The Holy Grail sought the first public demonstration of 100GbE SFP+ operating below 1.5 watts. These weren’t mere technical milestones. They were invitations to rethink what Ethernet could do. 

As any Monty Python fan knows, every quest eventually comes to an end. Ethernet, on the other hand, has always had a way of turning one quest into the next. And maybe that’s the real lesson of the Holy Cup and Holy Grail. The trophies were never the destination – they were reminders that there’s always another challenge worth chasing. 

Power to the People 

Power over Ethernet (PoE) is one of those technologies that quietly makes life easier. It’s elegant in its simplicity: one cable carrying both power and data. Today it feels so natural that it’s easy to forget there was a time when it wasn’t. Somewhere along the way, it stopped feeling revolutionary and became just how things are done.

Ideas this simple only become everyday reality when people trust them. As PoE found its way into more applications, from wireless access points and security cameras to lighting, industrial systems, and smart buildings, the Ethernet community came to realize that great power really does come with great responsibility. People needed reassurance that products from different manufacturers would work together without a second thought, exactly as Ethernet always promised they would. And that’s what the Ethernet Alliance set out to deliver.

Trust isn’t something you claim. It’s something you earn. Through its PoE Certification Program and its publicly searchable Product Registry, the Ethernet Alliance gave the industry an independent way to confirm that certified products met IEEE 802.3 PoE standards and would work together as intended. It wasn’t about putting another logo on a box. It was about giving people confidence that Ethernet would do what it has always done best: bring everything together.

One of the things I admire most is that the Ethernet Alliance never assumed it already knew the answers. It asked. Through its State of the PoE Market surveys, it listened to installers, integrators, designers, end users, and others working with PoE every day. The responses painted an encouraging picture of a technology that had quietly become part of everyday life, while also reminding us that interoperability and confidence still matter. Even technologies we take for granted depend on trust. And trust is built one reliable connection at a time.

 

The Journey Continues 

Looking back, it’s tempting to measure the Ethernet Alliance’s last twenty years by the Roadmaps, the demonstrations, Technology Exploration Forums, the Holy Cup and Grail, PoE certification program, or the countless technical breakthroughs along the way. But I don’t think that’s what I’ll remember most. I’ll remember the conversations. The ideas scribbled on whiteboards. The late-night debates that somehow turned into tomorrow’s innovations. Most of all, I’ll remember the people who never stopped believing that Ethernet’s best days were still ahead. 

After fifty years, Ethernet has become so woven into the tapestry of our everyday lives that it’s easy to forget just how extraordinary that really is. It’s Ethernet’s world and we all live in it. 

Here’s hoping we never stop asking, “What’s next?”
