Everyone's Laying Fiber. Who's Powering It?

Walk into any industry conference, open any trade publication, and you'll hear the same word over and over: fiber. And for good reason. 2025 was a record year for fiber-to-the-home, with millions of new residences passed and roughly six in ten U.S. households now within reach of a fiber connection.¹ The $42.45 billion BEAD program is set to push glass into places private capital never could, with the first funded connections coming online late this year.² Stadiums are re-cabling for large-scale events like the World Cup, the Super Bowl, and the Olympics. Cities are threading fronthaul to thousands of new small cells.

It's a fiber story. Everyone agrees on that.

But fiber doesn't light itself. It doesn't amplify a signal, run a radio, or keep a network on air during a thunderstorm or a sold-out event. Behind every strand of glass is a piece of equipment that needs power — reliable, correctly specified, code-compliant DC power. And that power is almost always the part of the project that gets planned last and noticed first when something goes wrong.

So, while the industry races to answer who's laying the fiber, there's a quieter question that decides whether any of it actually works: who's powering it?

The part of the network nobody photographs

Fiber gets the ribbon-cutting. Power gets the outage report.

Look closely at any of the environments driving today's build-out and the pattern is the same. The connectivity layer gets the headlines. The power layer keeps it alive.

In stadiums and venues, the fan experience everyone markets — in-seat ordering, mobile ticketing, live streaming from a packed bowl — rides on distributed antenna systems and private 5G. Those remote nodes, radios, and headend racks all run on DC power, and on event day there is no margin for error. The network has to perform the first time, every time, in front of seventy thousand people and a broadcast audience. When it does, nobody thinks about the power feeding it. When it doesn't, nothing else matters.

On towers, the industry talks about fiber to the antenna. Fair enough — but power goes up that tower too, to the radio heads at the top and the equipment in the shelter at the base. Battery plants, rectifiers, –48V distribution, and proper grounding against lightning are what keep a site on air between truck rolls. Every radio added in the name of densification is another power run that has to be done right.

In residential and FTTH builds, the glory is in homes passed. But the active network between the central office and the living room — the powered cabinets, nodes, and remote terminals, the equipment serving multi-dwelling units — all draws power. It's the line item that rarely makes the press release and always has to be in the ground and energized before a single customer gets service.

Across cities and municipalities, small cells and smart-city nodes are multiplying on poles and in rights-of-way. Each one needs fiber fronthaul, yes — and each one needs power. Public-safety networks that a city is legally obligated to keep running need power that stays up when the grid doesn't.

Four very different environments. One thing in common: the fiber is the story, but the power is the dependency.

Why the power layer decides the outcome

Here's what a decade of field experience teaches: the power side is where good projects quietly go sideways.

It's not usually a dramatic failure. It's an underspecified cable that overheats months after the crew has moved on. It's an AC-rated component pressed into DC service. It's low-smoke, non-halogen ratings skipped to save a few dollars in a space where code — and life safety — demanded them. It's a battery plant that was never quite sized for the load the site actually grew into.

And just as often, it's not an engineering problem at all. It's a timing problem: the power cable that was 12 weeks out when the cutover was scheduled for next Tuesday. A network can be perfectly designed and perfectly funded and still sit dark because the unglamorous material that energizes it didn't show up.

That's the uncomfortable truth behind the fiber headlines. You can win the race to lay glass and still lose the project on power.

The lesson every build-out eventually teaches

That's a lesson the industry relearns on every cycle of investment: reliability isn't a feature added at the end, it's a discipline built in from the first spec. Cable rated for the environment it's actually entering, not the one that's convenient to assume. Testing and certification that hold up under an inspector's scrutiny, not just a data sheet. Lead times are treated as part of the project schedule, not an afterthought to it.

None of that is glamorous, and it was never going to be. GR-347-Core audits, UL and CSA listings, low-smoke non-halogen ratings — these are the unglamorous disciplines sitting behind every stadium headend, tower shelter, and municipal node that stays lit when it counts. Three decades of distributing Southwire® TelcoFlex® have taught Electro Wire the same lesson from the supply side: the projects that go smoothly are the ones where power was planned, sourced, and staged with the same rigor as the fiber itself.

Fiber will keep making the headlines, and it should — connectivity is the point of all this build-out. But the industry's next hard lesson will look a lot like its last one: the builds that land on time and on budget are the ones where somebody treated the power layer as seriously as the glass, from the first drawing to the last truck roll.

Everyone's laying fiber. The question worth asking earlier in the project — not after the outage — is still the one we started with: who's powering it?
