Harmonic's path will be paved with a lot more fiber and AI at the edge.

Harmonic's path will be paved with a lot more fiber and AI at the edge. Harmonic expects revenues to grow 10% to 13% by 2030 as it expands its fiber business with both cable operators and telcos while branching into areas such as edge AI compute. September 16, 2026 Amid its transition to a "pure-play broadband company" following the recent sale of its video business to MediaKind, Harmonic is now looking to bring more diversity and durability into the business. That means shifting toward more recurring (and more predictable) revenue and leaning less on sales to its traditional tier 1 marquee customers (such as Comcast and Charter Communications), according to the execs who spoke at Harmonic's investor day. And while DOCSIS and hybrid fiber/coax (HFC) will continue to get plenty of attention, Harmonic's revised strategic focus also means the vendor will be putting much more emphasis on passive optical network (PON) technology for both cable operators and telcos, and on edge AI/compute platforms for deployment in cable headends and hubs and telco central offices. Underpinning it all will be cOS, a software platform Harmonic initially developed to support virtual cable modem termination systems (vCMTS) that has also been adapted to orchestrate and manage fiber-based networks. 50-Gig PON viewed as a 'pivot point' Harmonic's access network business is also evolving toward fiber. Initially, that strategy centered on cable operators that deployed PON for network edge-outs; rural, subsidized builds; and multiple-dwelling units (MDUs). But Harmonic is also expanding into the world of telco fiber, starting largely with non-tier 1 operators. The company expects to generate about $70 million from its fiber business in 2026. Though "DOCSIS will continue to be a major engine for us," Harmonic is ready to tackle the telco market in a "serious way," said the company's president and CEO, Nimrod Ben-Natan. Harmonic intends to go further up market with fiber products when operators are ready to deploy 50-Gig technology in earnest. The transition to 50-Gig technology, which is expected to take hold in 2028 and 2029, will serve as Harmonic's "pivot point" into the tier 1 telco market, said CFO Walter Jankovic. Harmonic's bigger emphasis on fiber and growing the telco business will put it in more direct competition with Adtran and Calix in the US, and elsewhere with Huawei and Nokia, Raymond James analyst Simon Leopold pointed out in a research note. Targeting data centers and the AI edge. Harmonic will be keying on non-residential PON tech that can support connectivity in the data center and enterprise markets, and effectively serve as an alternative to point-to-point Ethernet. Tied in, the vendor will focus on the edge compute opportunity as cable operators and telcos free up space in headends, hubs and central offices that sit close to subscribers and have ample power and space to support the compute needed for AI applications. "This is more of an edge inference [opportunity]," Ben-Natan said. "It's not about the quantity and the capacity of hundreds of thousands of GPUs. It's more about what's really important to be at the edge." Notably, Comcast and Charter/Cox are already pursuing this part of the market. Last week, Comcast announced it is integrating Fastly's software into its national network to reduce latency and improve video quality and prepare for emerging latency-sensitive AI services. But that won't be where Harmonic will focus its AI edge efforts. Ben-Natan noted that Harmonic will provide an aggregated offering targeted to a "longer tail of customers" that do not have the in-house resources to deploy and support their own edge AI compute platforms. Setting a 'floor' for revenue growth. Harmonic put some numbers behind the vision for how it sees its business changing in the next three years. Although the company has not yet determined the size of the addressable market for the edge AI compute opportunity, it forecasts an addressable market of $6.4 billion to $7.4 billion by 2030 for connectivity (DOCSIS, fiber and data center/enterprise) and "intelligence", a category of software-based and AI-assisted products designed to help operators monitor, manage and repair their networks. The "floor" Harmonic is targeting for compound annual growth from 2026 to 2029 is in the range of 10% to 13%, Jankovic said. That forecast does not include any fiber business with tier 1 operators, 50-Gig tech sales or any potential upside coming from the edge AI compute market. "The outlook sounds reasonable and conservative; however, gaining traction with telco operators, as well as security sales with network management software will present challenges," wrote Raymond James' Leopold. Diversifying the business is a big focus going forward. About 37% of Harmonic's revenues currently are derived from what it calls rest-of-market (ROM), a segment that does not include Comcast and Charter. Harmonic expects that figure to rise to a range of 55% to 60% by 2030. Recurring revenues from intelligence. Harmonic also expects about 22% to 25% of total revenues to be recurring, a portion of which will come from the new intelligence products and services, including Harmonic's recently announced "SensAI" platform, which is already being used by operators such as GCI and Hotwire. Harmonic expects about 10% of total revenues to come from the intelligence category over the next three years. "The key message is we're funding these investments organically," Jankovic said. "It's more than building a bigger business; it's building a more durable business." Some analysts asked what Harmonic will need to do to get the right people on board to pursue cable and telco business. Ben-Natan said a growing percentage of new employees have already been coming from the "pure telco" side of the business, along with a subset that have experience across both cable and telco. "This is a capability that we already have...and we're going to expand that," he said. Ben-Natan acknowledged that pursuing tier 1 telcos is a "different ballgame," but he reiterated that it's an area Harmonic is not pursuing until the 50-Gig PON opportunity is ripe. "But engaging with [tier 1] customers is not something new for us," he said. Operators also taking diverse paths. Harmonic's focus on both PON and HFC reflects how its customers are moving forward. Indeed, operators' strategies vary widely. Bluepeak, a cable operator in the Midwest and Great Plains, for example, originally planned to upgrade its HFC plant to DOCSIS 4.0 but later decided instead to upgrade the bulk of that footprint to PON. "It was a pretty big shift for us," Cash Hagan, Bluepeak's COO, said on an operator panel held during the two-hour investor event. But he pointed out that Bluepeak could still use the same underlying cOS platform regardless of the access technology it is deploying. Meanwhile, Armstrong, which operates in the Northeast, is focused on PON but is also working with Harmonic for upgrades of its DOCSIS networks, said Eric Svenson, the company's VP of technology engineering and operations. Mediacom Communications is deploying XGS-PON in some targeted areas, but it is largely focused on providing multi-gigabit symmetrical services via upgrading HFC networks that pass about 3.1 million homes. Mediacom operates across 22 states, primarily in the Midwest and South. "We felt like we needed to do it really quickly. That's what kept us attracted to the DOCSIS roadmap," said Mediacom CTO JR Walden. Mediacom has already upgraded more than 650,000 homes connected to HFC and has deployed north of 700 nodes powered by new "unified" DOCSIS 4.0 silicon from Broadcom. "If we had adopted a fiber-to-the-home-first strategy, an overbuild strategy, we don't think we would've gotten to nearly that many homes" in the same timeframe, Walden said. In addition to providing more speed and capacity, Walden also believes that next-gen DOCSIS technologies perform well in areas where PON tends to get high marks. "An upgraded DOCSIS network is every bit as reliable as a PON network, at least the way we see it," he said.

ADTRAN Q2 revenue rises 6% to $281M as optical networking climbs 22% and hyperscaler sales nearly double

ADTRAN Holdings reported second-quarter 2026 revenue of $281.1 million, up 6.1% year over year, though results fell short of guidance due to a delayed customer project and supply constraints. Optical Networking was the primary growth driver, with revenue rising 22% to $109.7 million. Enterprise, government and cloud revenue increased 47%, whilst hyperscaler revenue nearly doubled. Chairman and CEO Tom Stanton attributed the miss to timing issues rather than weakening demand, noting the affected customer has reaffirmed deployment plans. Component shortages limited the company's ability to fulfil incremental orders and created unfavourable product mix. Non-GAAP gross margin fell to 40.7%. ADTRAN forecast third-quarter revenue of $275 million to $295 million with a 1.5% to 5.5% non-GAAP operating margin.
