The Transponder Is Dead. Long Live the Transponder.
800ZR pluggables have won the router port, but the money in optical transport is sliding to the line system and the fiber underneath it.
The Fiber Supply Chain Is Coming Home, and the Glass Is the Bottleneck
Tariffs, Buy America rules and hyperscaler checkbooks are pulling fiber manufacturing back to the Carolinas, but through 2028 the pinch will be preforms, germanium and draw towers, not cable plants.
The Gigawatt Campus Is a Fiber Problem Before It Is a Power Problem
Stargate, Colossus, Hyperion and Fairwater will each consume millions of fiber terminations, and the cable, connector and installer base is being rebuilt through 2028 to feed them.
Kill the DSP, Keep the Cage: Why Linear Optics Will Outsell CPO Through 2028
Co-packaged optics is finally shipping from Broadcom and Nvidia, but DSP-less pluggables capture most of the power saving with none of the serviceability risk, and that is where hyperscaler volume is going for the next three years.
The AI Fabric Is Going Back to the Switchboard
Optical circuit switches that move mirrors instead of packets are leaving Google's TPU pods and heading for Nvidia's racks, and the fiber plant will have to be rebuilt around them.
The Power Company Is Your Next Fiber Provider
By 2029, a third or more of rural America's fiber passings will sit on networks owned or carried by electric utilities, and the grid-modernization budget is what's paying for it.
The Fiber Famine: Why NVIDIA and Corning Just Rewrote the Rules of AI Infrastructure
AI data centers need 36x more fiber than standard servers. Lead times are already a year out. NVIDIA just secured its own supply chain — and the rest of the industry is about to feel the squeeze.

The Invisible Network: How Existing Fiber Will Become the World's Largest Sensor
Distributed fiber sensing could turn millions of kilometers of installed cable into earthquake detectors, security systems, and environmental monitors
1.6T Is Shipping. Here's What the Transceiver Roadmap Looks Like Through 2029.
The industry just crossed the 1.6 terabit threshold. What comes next — 3.2T, co-packaged optics, and the end of the pluggable era — is already in the labs.
The 6G Fiber Foundation: What the Industry Has to Build Before 2030
6G standards are still being written, but the fiber infrastructure required to support them isn't waiting. The densification wave is already underway.
The AI Inference Edge: Why Fiber Is Moving Closer to the User Than It Ever Has
Training AI models requires massive centralized compute. Running them in real time doesn't — and the infrastructure requirements for inference are reshaping where fiber goes and why.
BEAD Round Two and What Comes After: The $65B Rural Fiber Story Still Being Written
BEAD's first round created the largest rural broadband deployment in American history. The second round will determine whether that deployment produces connected communities or stranded assets.
Co-Packaged Optics Goes to Volume: The Supply Chain That Has to Be Built by 2028
CPO is no longer a research project. It's a production ramp. The component supply chain required to build a trillion dollars of AI infrastructure is being invented right now.
Hollow-Core Fiber Hits the Field: The First Commercial Deployments Are Live
After two decades of laboratory promise, hollow-core fiber is being pulled through real conduit in real cities. Here's what the first deployments reveal about where this goes next.
Multi-Core Fiber Is Moving Out of the Lab. The Network Isn't Ready.
Spatial division multiplexing promised to multiply fiber capacity without multiplying fiber. The technology works. What doesn't work yet is everything else.
Post-Quantum Networks: The Fiber Industry's $40B Upgrade Cycle Starts Now
Quantum computers capable of breaking current encryption aren't here yet. But the network upgrades required to be ready for them take a decade to complete. The clock is running.
Silicon Photonics Hits Volume: The $22B Market Rewriting the Fiber Component Industry
Silicon photonics promised to bring semiconductor economics to optical components. In 2026, it's delivering — and the implications for the traditional fiber component supply chain are severe.
Subsea Cable Boom, Act Two: The Routes That Will Define the Next Decade
The first subsea cable boom was about connecting continents. The second is about redundancy, sovereignty, and the hyperscalers' decision to own their ocean infrastructure outright.
