Adtran’s CEO retains focus on service providers that connect data centers and cloud providers
Key Highlights
- Adtran is targeting service providers upgrading optical backbones to meet AI-driven bandwidth demand.
- Hyperscaler revenue grew more than 200% year over year in the third quarter.
- MicroMux Quattro adapts 400GbE ports for multiple 100G or 200G connections, with release planned for the first half of 2027.
- Adtran expects customer trials of its 800G LiteWave800 LPO module to begin in the first half of next year.
- Third-quarter revenue was $281.2 million; fourth-quarter guidance is $272 million to $292 million.
Adtran is focused on continuing to capture optical networking opportunities with service providers upgrading their network capabilities to accommodate data center providers with wholesale dark and lit fiber services.
Whether it is large providers like AT&T or Verizon or emerging operators like Optimum, the service provider community is enhancing their optical network backbones to serve an increasingly growing set of bandwidth demands driven by AI.
“While we are growing with cloud providers, we are deliberately staying focused on the service providers that connect them, where our deep customer relationships and differentiated technology give us a strong position,” Stanton said. “And as some competitors turn their attention elsewhere, we intend to capture the opportunity that they create.”
Beyond connecting AI infrastructure with carriers, Adtran sees continued growth potential in data center interconnection (DCI) in the cloud provider market.
Adtran’s third-quarter revenue from hyperscaler customers grew more than 200% year-over-year.
“We are positioning ADTRAN to participate directly in its build-out with solutions at three critical points in the cloud network architecture,” Stanton said. “Data center interconnect is where we have long served cloud providers, and we are starting to see the benefits of our investments in this area.”
Pluggable interest rises
While providing optical equipment to service providers supporting data center operators remains a priority for Adtran, the vendor is seeing a growing opportunity inside data centers.
Internal data center bandwidth needs are rising as AI creates unprecedented demand, and increasingly large custom GPU clusters must connect to support AI workloads.
Adtran is addressing this need with its MicroMux Quattro. This pluggable aggregation device converts a single high-speed 400GbE QSFP-DD port on a router or switch into four independent 100Gbps or two independent 200Gbps interfaces.
For data center providers and hyperscalers, the MicroMux Quatro offers modern 400G switch/router hardware that supports legacy 100G/200G server or inter-switch links without redesigning or retrofitting the network.
“At the cloud handoff, where cloud providers connect to service providers or other cloud providers, we plan to release our MicroMux Quattro solution in the first half of 2027,” Stanton said. “It is generating significant interest from hyperscalers, content providers and wholesale network providers.”
He added that Adtran said some OEMs as well as hyperscalers are evaluating the MicroMux Quattro solution. “Some of the hyperscalers have pushed OEMs to come our way for both of those products,” Stanton said. “We have some early Quattro that are out in testing.”
LPO opportunities emerge
Along with pluggables, Adtran is seeing growing interest in its linear pluggable optics (LPO) offerings.
In March, Adtran launched LiteWave800, an ultra‑low‑power 800 Gbps DR8 linear pluggable optics (LPO) module to help data centers address the power, latency, thermal and bandwidth demands of AI and machine-learning (ML) workloads.
Operating at just 1pJ/bit and consuming only 0.8W, Adtran’s LPO product is centered on reducing energy consumption.
Stanton emphasized that “we have strong interest in the LPO product” from large data center customers.
“Our Lightwave 800 development remains on track with customer trials expected to begin in the first half of next year and production scaling in the second,” he said.
While he did not provide a specific timeline, he added that Adtran plans to release various versions of its LPO product.
“The product is not singular,” Stanton said. “We have different versions of that product that will be coming out over the next probably three years or so. But we've got very good interest in our very first product.”

Optical leads growth
Adtran’s third-quarter results were dominated by another quarter of growth in its optical division, driven by momentum with hyperscalers and European service providers.
Stanton said these growth drivers are diversifying its customer “reach across service providers, cloud providers, and enterprise markets, helping us build a broader and more diversified customer base.”
“Optical remained a primary growth engine with revenue increasing 11% year-over-year and 4% sequentially, supported by particularly strong performance in the U.S.,” he said. “These results are consistent with our expectations entering the year for growth to build throughout 2026.”
The vendor also saw gains in Access & Aggregation. Led by strength in Europe, revenue grew 5% year over year despite a slowdown with one of its largest customers due to timing adjustments in ongoing projects.
Stanton noted that “we are pleased with where we are with that customer and still expect orders to return to normalized levels in Q1 of next year.”
In Subscriber Solutions, revenue rose 4% sequentially, driven by gains in carrier Ethernet.
“Taken together, these results reflect a solid demand environment across our core markets, even as supply availability continues to influence timing,” Stanton said.
For the quarter, Adtran reported revenue of $281.2 million, up 0.6% year over year.
Despite the gains, Adtran’s third-quarter revenue fell slightly below the midpoint of its guidance range because of a challenging supply environment.
Looking towards the fourth quarter of 2026, Adtran expects revenue to be within a range of $272 million to $292 million.
