Marketplace All-in-One · Raising the “speed limit” on AI’s “information highway” · 26 Jan 2026 podcast

It's literally humming in this lab.

What's going on in here?

All right, let's go.

There were wires everywhere.

Workers in jeans and T-shirts hovered over screens filled with code.

Satish pulled out a rack of little yellow plugs.

Kind of like the Ethernet cables you might stick into your home computer.

AWS has built about 9 million kilometers of fiber cable to link computers around the world.

It's enough to stretch to the moon and back 11 times.

And it's all connected with fiddly little plugs like these.

So the ergonomics of actually plugging those individually.

Those little innovations, like a cable that's easier to plug in, might seem small, but that's the infrastructure required to make almost $2 trillion of AI investment pay off.

We'll be right back.

This is Marketplace Tech.

I'm Megan McCarty Carino.

Inside, a research and development lab of Amazon Web Services that is working on new technology for the AI infrastructure build-out.

Satish Vangala, Director of Network Product Development, showed me these devices, they're called transponders, that convert electric signals, aka data, into light waves.

They look a little bit like nail clippers.

I mean, when we were looking at, you know, just the little sockets and how you're engineering all of this stuff, it just really calls to mind how the infrastructure build-out, it's all these little pieces that have to come together to make it work.

What are the challenges on your side, on the networking side, to meeting that demand?
