Ciena to acquire Nubis Communications for high performance optical and electrical interconnects to support AI workloads
New Ciena Acquisition:
Today, Ciena announced it will acquire electronics startup Nubis Communications, a privately-held company headquartered in New Providence, New Jersey for $270 million. Nubis specializes in high-performance, ultra-compact, low-power optical and electrical interconnects tailored to support AI workloads. The Nubis acquisition will give Ciena access to technology that supports a wider range of data center use cases. It is is expected to close during Ciena’s fiscal 4th quarter.
Nubis’ solutions complement Ciena’s existing high-speed interconnects portfolio and will enable new capabilities to support growing AI workloads by significantly increasing scale up and scale out capacity and density inside the data center. The Nubis portfolio includes two key technologies:
- Co-Packaged Optics (CPO) / Near Packaged Optics (NPO): Nubis’ compact, high-density optical modules deliver ultra-fast data transfer using light instead of traditional electrical signals. Supporting up to 6.4 Tb/s full-duplex bandwidth, these modules are optimized for low-latency, low-power operation – making them ideal for scaling AI systems. Combined with Ciena’s high-speed SerDes, Nubis’ optical engines enable differentiated CPO solutions to address high-performance connectivity needs inside and between racks.
- Electrical ACC: Nubis’ advanced analog electronics enable Active Copper Cables (ACC) to support high-speed data transmission, allowing data to travel up to 4 meters at speeds of 200 Gb/s per lane. This low-power, low-latency solution helps customers connect more AI accelerators across racks without the limitations of traditional copper or DSP-based solutions
Nubis has developed two products to increase bandwidth and reduce latency within and between data center racks:
- XT Optical Engines is a series of optical modules that support up to 6.4 Tbps of full-duplex bandwidth while using light instead of traditional electrical signals.
- Nitro Linear Redriver aims to improve the performance of all the copper cables that are wired into the data center. Bloomberg has predicted copper usage in North American data centers could increase by 1.1-2.4 million tons by 2030 as “AI demands mount.”
“The acquisition of Nubis represents a significant step forward in Ciena’s strategy to address the rapidly growing demand for scalable, high-performance connectivity inside the data center, driven by the explosive growth of AI-related traffic,” said David Rothenstein, Chief Strategy Officer at Ciena. “With ownership of these key technologies for a wider range of use cases inside the data center, we are expanding our competitive advantage by advancing development of differentiated solutions, reducing development costs, and driving long-term efficiency and profitability. Nitro also supports up to 4m of reach for 200G per lane active copper cables, far beyond the limits of passive copper and legacy analog solutions. This is a game-changer for AI infrastructure, where short-reach, high-bandwidth copper is preferred for cost and latency reasons,” Rothenstein added.
“The Nubis team is thrilled to join Ciena and enhance its industry-leading portfolio with our breakthrough interconnect technologies,” said Dan Harding, CEO of Nubis. “Together, we will advance Ciena’s data center strategy by delivering reliable, high-quality, and high-performance interconnect solutions to support the next generation of AI workloads.”
Dell’Oro VP Jimmy Yu said Nubis is probably “one of [Ciena’s] most forward-looking” acquisitions, since the company is assembling the pieces it thinks are necessary to support future data center networking. “This acquisition aligns well with Ciena’s overall strategy to expand into the data center market, and it likely played a role in their decision to exit future investments in broadband PON,” Yu said.

Ciena Cutting Back on Residential Broadband Access investments to focus on AI and Coherent Optics:
The Nubis takeover comes shortly after Ciena announced it will reduce investment in residential broadband access (e.g. 25G PON) to focus more on AI applications and its coherent optics business. Ciena CEO Gary Smith said on the company’s Q3 2025 earnings call:
“Folks are more concentrated on 10-gig and driving that out, and there’s a good market for that. As we looked at our overall portfolio and our investments in [25-gig], we see so much opportunity in these different AI workloads that we want to continue to really make sure we’re heavily invested in that….To be clear, we will continue to sell and support our existing broadband access products. However, we will be limiting our forward investments only to strategic areas such as DCOM [1.].”
Note 1. DCOM refers to Ciena’s data center out-of-band management solution, which involves replacing bulky legacy hardware like copper cabling and console servers with passive optical network (PON) technology.
Dell’Oro Group’s Jimmy Yu thinks Ciena’s move to re-allocate R&D dollars makes sense so that the company is not spread too thin and [misses] out the biggest opportunity sitting in front of them. “My guess is that to address the future of AI workloads and AI data center interconnect, Ciena will need to not only maintain their cadence on launching new high performance coherent optics like the WaveLogic 6e for long distance 1.6 Tbps connections, but also optical devices for shorter distances like 800 ZR/ZR+ plugs and even shorter distances that take them inside the data center,” Yu explained.
Ciena considers the WaveLogic series its bread-and-butter for coherent optics. The company in Q3 gained 11 new customers for its WaveLogic 6 Extreme product, bringing its total customer tally to 60. Companies deploying WaveLogic 6 include operators such as Arelion, Lumen and Telstra, which are upgrading their networks to support demand from cloud customers.

T-Mobile’s new CEO Srini Gopalan faces fierce competition from AT&T, Verizon and MVNOs
Today, T-Mobile US promoted Srini Gopalan, from chief operating officer (COO) to CEO. Gopalan is a veteran of parent company Deutsche Telekom as the head of its German home market. He has also held executive roles at Indian telecom company Bharti Airtel, Capital One and Vodafone.
Current CEO Mike Sievert will move into a newly created vice-chairman position. He said in a WSJ interview that he would continue to influence the company’s strategy. “I recruited Srini starting about a year ago with the idea that this day would come,” Sievert said.
T-Mobile has often been recognized for its high-speed 5G network and standalone 5G network capabilities. The “un-carrier” capitalized on the Sprint merger (announced in April 19, 2018; finalized April 1, 2020) to grow its customer base, winning share in both postpaid and prepaid markets and positioning itself as the industry’s fastest-growing carrier. Under Sievert’s tenure, T-Mobile drew millions of broadband customers from cable industry-dominated markets by using its 5G network to beam internet service into homes and businesses. The company is also exploring the wired-broadband business, including through a roughly $5 billion investment in a joint venture with investment company KKR.
Wireless carriers have been grappling with slowing subscriber growth, rising competition and increasingly cautious consumers unwilling to pay for premium plans. T-Mobile’s strongest competitors have been the other two major nationwide mobile carriers Verizon and AT&T. However, the growing market for Mobile Virtual Network Operators (MVNOs), especially from cablecos like Comcast and Charter, has also introduced a new, significant competitive challenge.
Yet both Gopalan and Sievert said the business can keep up the pace as the mobile-phone market matures. “We really like wireless as a neighborhood in the U.S., and we have clearly outperformed everyone else,” Gopalan said in an interview, adding that T-Mobile’s home broadband business has more room to grow. “We’ve shown our hand in fiber. We like pure-play fiber, we like the idea of scaling that business, got two acquisitions already and we’re looking at what other value-creator deals are there.”
Gopalan “brings a wealth of experience a
nd is a very impressive leader, and they’ve handled this transition exceptionally well. I don’t expect there to be any fall-off at all in T-Mobile’s performance,” MoffettNathanson analyst Craig Moffett said.
Craig wrote in a research note that a new wholesale deals with Comcast and Charter could give those cable operators an even stronger price edge in business wireless — a market where T-Mobile has been clawing share. “Cable wins. And T-Mobile wins as well,” Moffett wrote, while raising questions about whether the tie-up could lead to deeper partnerships that would reshape the sector. He added that, while T-Mobile is well-positioned in consumer wireless, cable’s entry into enterprise could spark new price wars, making execution under new leadership even more critical.C
T-Mobile has made several acquisitions since it acquired Sprint in 2020. It spent $1.35 billion to acquire Ryan Reynolds’s Mint Mobile in May 2024, giving the company access to more value-conscious phone plan shoppers.
The company has also closed deals for fiber-optic plays Metronet ($4.9 billion), US Cellular ($4.4 billion), and Lumos ($950 million).

AI Data Center Boom Carries Huge Default and Demand Risks
“How does the digital economy exist?” asked John Medina, a senior vice president at Moody’s, who specializes in assessing infrastructure investments. “It exists on data centers.”
New investments in data centers to power Artificial Intelligence (AI) are projected to reach $3 trillion to $4 trillion by 2030, according to Nvidia. Other estimates suggest the investment needed to keep pace with AI demand could be as high as $7 trillion by 2030, according to McKinsey. This massive spending is already having a significant economic impact, with some analysis indicating that AI data center expenditure has surpassed the total impact from US consumer spending on GDP growth in 2025.
U.S. data center demand, driven largely by A.I., could triple by 2030, according to McKinsey. That would require data centers to make nearly $7 trillion in investment to keep up. OpenAI, SoftBank and Oracle recently announced a pact to invest $500 billion in A.I. infrastructure through 2029. Meta and Alphabet are also investing billions. Merely saying “please” and “thank you” to a chatbot eats up tens of millions of dollars in processing power, according to OpenAI’s chief executive, Sam Altman.
- OpenAI, SoftBank, and Oracle pledging to invest $500 billion in AI infrastructure through 2029.
- Nvidia and Intel collaborating to develop AI infrastructure, with Nvidia investing $5 billion in Intel stock.
- Microsoft spending $4 billion on a second data center in Wisconsin.
- Amazon planning to invest $20 billion in Pennsylvania for AI infrastructure.

The spending frenzy comes with a big default risk. According to Moody’s, structured finance has become a popular way to pay for new data center projects, with more than $9 billion of issuance in the commercial mortgage-backed security and asset-backed security markets during the first four months of 2025. Meta, for example, tapped the bond manager Pimco to issue $26 billion in bonds to finance its data center expansion plans.
As more debt enters these data center build-out transactions, analysts and lenders are putting more emphasis on lease terms for third-party developers. “Does the debt get paid off in that lease term, or does the tenant’s lease need to be renewed?” Medina of Moody’s said. “What we’re seeing often is there is lease renewal risk, because who knows what the markets or what the world will even be like from a technology perspective at that time.”
Even if A.I. proliferates, demand for processing power may not. Chinese technology company DeepSeek has demonstrated that A.I. models can produce reliable outputs with less computing power. As A.I. companies make their models more efficient, data center demand could drop, making it much harder to turn investments in A.I. infrastructure into profit. After Microsoft backed out of a $1 billion data center investment in March, UBS wrote that the company, which has lease obligations of roughly $175 billion, most likely overcommitted.
Some worry costs will always be too high for profits. In a blog post on his company’s website, Harris Kupperman, a self-described boomer investor and the founder of the hedge fund Praetorian Capital, laid out his bearish case on A.I. infrastructure. Because the building needs upkeep and the chips and other technology will continually evolve, he argued that data centers will depreciate faster than they can generate revenue.
“Even worse, since losing the A.I. race is potentially existential, all future cash flow, for years into the future, may also have to be funneled into data centers with fabulously negative returns on capital,” he added. “However, lighting hundreds of billions on fire may seem preferable than losing out to a competitor, despite not even knowing what the prize ultimately is.”
It’s not just Silicon Valley with skin in the game. State budgets are being upended by tax incentives given to developers of A.I. data centers. According to Good Jobs First, a nonprofit that promotes corporate and government accountability in economic development, at least 10 states so far have lost more than $100 million per year in tax revenue to data centers. But the true monetary impact may never be truly known: Over one-third of states that offer tax incentives for data centers do not disclose aggregate revenue loss.
Local governments are also heralding the expansion of energy infrastructure to support the surge of data centers. Phoenix, for example, is expected to grow its data center power capacity by over 500 percent in the coming years — enough power to support over 4.3 million households. Virginia, which has more than 50 new data centers in the works, has contracted the state’s largest utility company, Dominion, to build 40 gigawatts of additional capacity to meet demand — triple the size of the current grid.
The stakes extend beyond finance. The big bump in data center activity has been linked to distorted residential power readings across the country. And according to the International Energy Agency, a 100-megawatt data center, which uses water to cool servers, consumes roughly two million liters of water per day, equivalent to 6,500 households. This puts strain on water supply for nearby residential communities, a majority of which, according to Bloomberg News, are already facing high levels of water stress.
“I think we’re in that era right now with A.I. models where it’s just who can make the bigger and better one,” said Vijay Gadepally, a senior scientist at the Lincoln Laboratory Supercomputing Center at the Massachusetts Institute of Technology. “But we haven’t actually stopped to think about, Well, OK, is this actually worth it?”

Ericsson integrates agentic AI into its NetCloud platform for self healing and autonomous 5G private networks
Ericsson is integrating agentic AI into its NetCloud platform to create self-healing and autonomous 5G private (enterprise) networks. This initiative upgrades the existing NetCloud Assistant (ANA), a generative AI tool, into a strategic partner capable of managing complex workflows and orchestrating multiple AI agents. The agentic AI agent aims to simplify private 5G adoption by reducing deployment complexity and the need for specialized administration. This new agentic architecture allows the new Ericsson system to interpret high-level instructions and autonomously assign tasks to a team of specialized AI agents.
Key AI features include:
- Agentic organizational hierarchy: ANA will be supported by multiple orchestrator and functional AI agents capable of planning and executing (with administrator direction). Orchestrator agents will be deployed in phases, starting with a troubleshooting agent planned in Q4 2025, followed by configuration, deployment, and policy agents planned in 2026. These orchestrators will connect with task, process, knowledge, and decision agents within an integrated agentic framework.
- Automated troubleshooting: ANA’s troubleshooting orchestrator will include automated workflows that address the top issues identified by Ericsson support teams, partners, and customers, such as offline devices and poor signal quality. Planned to launch in Q4 2025, this feature is expected to reduce downtime and customer support cases by over 20 percent.
- Multi-modal content generation: ANA can now generate dynamic graphs to visually represent trends and complex query results involving multiple data points.
- Explainable AI: ANA displays real-time process feedback, revealing steps taken by AI agents in order to enhance transparency and trust.
- Expanded AIOps insights: NetCloud AIOps will be expanded to provide isolation and correlation of fault, performance, configuration, and accounting anomalies for Wireless WAN and NetCloud SASE. For Ericsson Private 5G, NetCloud is expected to provide service health analytics including KPI monitoring and user equipment connectivity diagnostics. Planned availability Q4 2025.
Manish Tiwari, Head of Enterprise 5G, Ericsson Enterprise Wireless Solutions, adds: “With the integration of Ericsson Private 5G into the NetCloud platform, we’re taking a major step forward in making enterprise connectivity smarter, simpler, and adaptive.

Elon Musk: Starlink could become a global mobile carrier; 2 year timeframe for new smartphones
Yesterday, during a segment of the All-in Podcast dedicated to the SpaceX-EchoStar spectrum sales agreement [1.], Space X/Starlink boss Elon Musk was asked if this sets the industry down a path where Starlink’s end goal is to emerge as a global carrier that, effectively, would limit the role of regional carriers. “That would be one of the options,” Musk responded. Musk downplayed any threat against AT&T, Verizon and T-Mobile. The podcast section dedicated to the EchoStar agreement starts around the 16:50 mark. You can start watching at that point via this YouTube link.
Note 1. SpaceX’s $17 billion agreement with EchoStar includes $8.5 billion in stock, plus $2 billion of cash interest payments payable on EchoStar debt. Separately, AT&T’s is paying $23 billion – all in cash – for its acquisition of EchoStar’s spectrum.
Regarding the EchoStar spectrum deal, Musk said, “This is kind of a long term thing. It will allow SpaceX to deliver high bandwidth connectivity directly from the satellites to the phones.”
Musk said that deal would not seriously challenge the big three U.S. mobile carriers. He said:
“To be clear, we’re not going to put the other carriers out of business. They’re still going to be around because they own a lot of spectrum. But, yes, you should be able to have a Starlink, like you have an AT&T or T-Mobile or Verizon, or whatever. You can have an account with Starlink that works with your Starlink [satellite] antenna at home with … Wi-Fi, as well as on your phone. We’d be a comprehensive solution for high bandwidth at home and high bandwidth for direct-to-cell.”
“Could you buy Verizon?” Musk was asked. “Not out of the question. I suppose that may happen,” Musk said with a chuckle.
That idea at least “highlights the possibility that SpaceX could pursue additional spectrum,” LightShed Partners analysts Walter Piecyk and Joe Galone explained in this blog post. “We highly doubt SpaceX has any interest in the people or infrastructure of a telco, there are plenty of compelling spectrum assets in and outside of those carriers to consider.”
Getting smartphones equipped with chips to support those new frequency bands will take some time. Musk estimated that’s “probably a two-year timeframe.” LightShed Partners analysts agreed, “On devices, Elon’s two-year timeline for a Starlink phone isn’t surprising given spectrum banding, chip development, and satellite integration. He’s mused before that if phone manufacturers continued to hinder his technology that he “would make a phone as a forcing function to compete with them.”
Some analysts view MVNO agreements as Starlink’s best route to becoming a full scale mobile carrier of satellite and terrestrial wireless services.
“The most plausible business model is that Starlink partners with MNOs for them to resell the service or embed the service as part of their plans,” Lluc Palerm Serra, research director at Analysys Mason, told PCMag.
LightShed Partners agreed. Musk’s point that SpaceX isn’t out to displace the incumbent carriers “reinforced our view that securing an MVNO deal will be essential if SpaceX wants to deliver a Starlink phone directly to consumers,” LightShed’s Walter Piecyk and Joe Galone explained in this blog post.
“In parallel, we’re working on the satellites and working with the handset makers to add these frequencies to the phones,” Musk said. “And the phones will then handshake well to achieve high-bandwidth connectivity. The net effect is that you should be able to watch videos anywhere on your phone.”
AT&T CEO John Stankey addressed Starlink’s “mobile-first” possibility earlier this week at an investor conference. Starlink’s current access to spectrum, including what is coming way of EchoStar, isn’t enough to create a “robust terrestrial replacement,” he said. But he acknowledged that, with the right type of commitments, perhaps it could happen someday.
“EchoStar still owns the highly lucrative 700 and AWS-3 spectrum, in which we note that all three wireless carriers have a robust ecosystem,” TD Cowen analyst Gregory Williams wrote in a note earlier this week. “Whether EchoStar sells more [spectrum] in short order remains to be seen,” TD Cowen’s Williams wrote Monday, explaining that, with the FCC dispute resolved, it may hold onto its portfolio longer. “EchoStar is not a forced seller, now has an excellent balance sheet and liquidity, and may desire to hold onto the spectrum as long as possible for higher sale valuations at a later date,” he added.

Huge significance of EchoStar’s AWS-4 spectrum sale to SpaceX
EchoStar has entered into a definitive agreement to sell its entire portfolio of prized AWS-4 [1.] and H-block spectrum licenses to SpaceX in a deal valued at approximately $19 billion. The spectrum purchase allows SpaceX to start building and deploying upgraded, laser-connected satellites that the company said will expand the cell network’s capacity by “more than 100 times.”
This deal marks EchoStar/Dish Network’s exit as a mobile network provider (goodbye multi-vendor 5G OpenRAN) which once again makes the U.S. wireless market a three-player (AT&T, Verizon, T-Mobile) affair. Despite that operational failure, the deal helps EchoStar address regulatory pressure and strengthen its financial position, especially after AT&T agreed to buy spectrum licenses from EchoStar for $23 billion. 
The companies also agreed to a deal that will enable EchoStar’s Boost Mobile subscribers to access Starlink direct-to-cell (D2C) service to extend satellite service to areas without mobile network service.
……………………………………………………………………………………………………………………………………………………………
Note 1. The AWS-4 spectrum band (2000-2020 MHz and 2180-2200 MHz) is widely considered the “golden band” for D2C services. Unlike repurposed terrestrial spectrum, the AWS-4 band was originally allocated for Mobile Satellite Service (MSS).
…………………………………………………………………………………………………………………………………………………………..
The AWS-4 spectrum acquisition transforms SpaceX from a D2C partner into an owner that controls its dedicated MSS spectrum. The deal with EchoStar will allow SpaceX to operate Starlink direct-to-cell (D2C) services on frequencies it owns, rather than relying solely on those leased from mobile carriers like T-Mobile and other mobile operators it’s working with (see References below).
Roger Entner wrote that SpaceX is now a “kingmaker.” He emailed this comment:
“With 50 MHz of dedicated spectrum, the raw bandwidth that Starlink can deliver increases by 1.5 GBbit/s. This is a substantial increase in speed to customers. The math is 30 bit/s/hz which is LTE spectral efficiency x 50 MHz = 1.5 Gbit/s. “This agreement makes Starlink an even more serious play in the D2C market as it will have first hand experience with how to utilize terrestrial spectrum. It is one thing to have this experience through a partner, this a completely different game when you own it.”
The combination of T-Mobile’s terrestrial network and Starlink’s enhanced D2C capabilities allows T-Mobile to market a service with virtually seamless connectivity that eliminates outdoor dead zones using Starlink’s spectrum.
“For the past decade, we’ve acquired spectrum and facilitated worldwide 5G spectrum standards and devices, all with the foresight that direct-to-cell connectivity via satellite would change the way the world communicates,” said Hamid Akhavan, president & CEO, EchoStar. “This transaction with SpaceX continues our legacy of putting the customer first as it allows for the combination of AWS-4 and H-block spectrum from EchoStar with the rocket launch and satellite capabilities from SpaceX to realize the direct-to-cell vision in a more innovative, economical and faster way for consumers worldwide.”
“We’re so pleased to be doing this transaction with EchoStar as it will advance our mission to end mobile dead zones around the world,” said Gwynne Shotwell, president & COO, SpaceX. “SpaceX’s first generation Starlink satellites with Direct to Cell capabilities have already connected millions of people when they needed it most – during natural disasters so they could contact emergency responders and loved ones – or when they would have previously been off the grid. In this next chapter, with exclusive spectrum, SpaceX will develop next generation Starlink Direct to Cell satellites, which will have a step change in performance and enable us to enhance coverage for customers wherever they are in the world.”
EchoStar anticipates this transaction with SpaceX along with the previously announced spectrum sale will resolve the Federal Communications Commission’s (FCC) inquiries. Closing of the proposed transaction will occur after all required regulatory approvals are received and other closing conditions are satisfied.
The EchoStar-Space X transaction is structured with a balanced mix of cash and equity plus interest payments:
-
Cash and Stock Components: SpaceX will provide up to $8.5 billion in cash and an equivalent amount in its own stock, with the valuation fixed at the time the agreement was signed. This 50/50 structure provides EchoStar with immediate liquidity to address its creditors while allowing SpaceX to preserve capital for its immense expenditures on Starship and Starlink development. A pure stock deal would have been untenable for EchoStar, which is saddled with over $26.4 billion in debt, while a pure cash deal would have strained SpaceX.
-
Debt Servicing: In a critical provision underscoring EchoStar’s dire financial state, SpaceX has also agreed to fund approximately $2 billion of EchoStar’s cash interest payments through November 2027.
-
Commercial Alliance: The deal establishes a long-term commercial partnership wherein EchoStar’s Boost Mobile subscribers will gain access to SpaceX’s next-generation Starlink D2C service. This provides a desperately needed lifeline for the struggling Boost brand. More strategically, this alliance serves as a masterful piece of regulatory maneuvering. It allows regulators to plausibly argue that they have preserved a “fourth wireless competitor,” providing the political cover necessary to approve a deal that permanently cements a three-player terrestrial market.
The move comes amid rapidly increasing U.S. mobile data usage. In 2024, Americans used a record 132 trillion megabytes of mobile data, up 35% over the prior all-time record, industry group CTIA said Monday.
