Dell’Oro: Abysmal revenue results continue: Ethernet Campus Switch and Worldwide Telecom Equipment + Telco Convergence Moves to Counter Cable Broadband
Dell’Oro Group recently reported that:
1. 2Q 2024 worldwide Ethernet Campus Switch revenues contracted year-over-year for the third quarter in a row. Ethernet campus switch sales hit an all-time high in 2Q 2023 and a year later, vendors are suffering in comparison.
“We expect another year-over-year contraction in sales next quarter, in 3Q 2024,” said Siân Morgan, Research Director at Dell’Oro Group. “However, the outlook is improving, and the Ethernet Campus Switch market is expected to return to growth in 4Q 2024.”
“While the economy in China remains soft, Huawei grew year-over-year campus switch revenues across the rest of Asia Pacific and CALA. Over half of Huawei’s campus switch sales were generated outside China,” added Morgan.
Additional highlights from the 2Q 2024 Ethernet Switch–Campus Report:
- The contraction in Ethernet campus switch sales was broad-based across both modular and fixed form factors, all verticals and regions.
- Sales to North America fell the most of any macro-economic region.
- Cisco grew campus switch revenues on a quarter-over-quarter basis, for the first time in a year.
The Dell’Oro Group’s Ethernet Switch–Campus Quarterly Report offers a detailed view of Ethernet switches built and optimized for deployment outside the data center, to connect users and things to the Local Area Networks. The report contains in-depth market and vendor-level information on manufacturers’ revenue, ports shipped, and average selling prices for both Modular and Fixed, and Fixed Managed and Unmanaged Ethernet Switches (100 Mbps, 1/2.5/5/10/25/40/50/100/400 Gbps), Power-over-Ethernet, plus regional breakouts as well as split by customer size (Enterprise vs. SMB) and vertical segments.

2. Preliminary findings indicate that worldwide telecom equipment revenues across the six telecom programs tracked at Dell’Oro Group—Broadband Access, Microwave & Optical Transport, Mobile Core Network (MCN), Radio Access Network (RAN), and SP Router & Switch—declined 16% year-over-year (Y/Y) in 2Q24, recording a fourth consecutive quarter of double-digit contractions. Helping to explain the abysmal results are excess inventory, weaker demand in China, challenging 5G comparisons, and elevated uncertainty.
Regional output deceleration was broad-based in the second quarter of 2024, reflecting slower revenue growth on a Y/Y basis in all regions, including North America, EMEA, Asia Pacific, and CALA (Caribbean and Latin America). Varied momentum in activity in the first half was particularly significant in China – the total telecom equipment market in China stumbled in the second quarter, declining 17% Y/Y.
The downward pressure was not confined to a specific technology, and initial readings show that all six telecom programs declined in the second quarter. In addition to the wireless programs (RAN and MCN), which are still impacted by slower 5G deployments, spending on Service Provider Routers fell by a third in 2Q24.
Supplier rankings were mostly unchanged. The top 7 suppliers in 1H24 accounted for 80% of the worldwide telecom equipment market and included Huawei, Nokia, Ericsson, ZTE, Cisco, Ciena, and Samsung. Huawei and ZTE combined gained nearly 3 percentage points of share between 2023 and 1H24.
Supplier positions differ slightly when we exclude the Chinese market. Despite the ongoing efforts by the U.S. government to curb Huawei’s rise, Huawei is still well positioned in the broader telecom equipment market, excluding China, which is up roughly two percentage points relative to 2019 levels.
- Even with the second half of 2024 expected to account for 54% of full-year revenues, market conditions are expected to remain challenging in 2024.
- The Dell’Oro analyst team collectively forecasts global telecom equipment revenues to contract 8 to 10% in 2024, even worse than the 4% decline in 2023.
3. U.S. Telcos Betting on Convergence and Scale To End Cable’s Broadband Reign
U.S. telcos have been very active the past two weeks with deals and partnerships.
- Verizon announced a $20B deal to acquire Frontier Communications and push the combined entity to a fiber footprint of 25 million homes and a fixed wireless footprint of approximately 60 million homes.
- AT&T announced partnerships with four open access network providers to help it expand the reach of its fiber services outside its existing wireline footprint. AT&T will serve as an ISP in these markets, delivering both residential and enterprise services via these partnerships. AT&T is on track to pass a minimum of 30 million homes with fiber by 2025 in its own footprint, as well as an additional 1.5 million homes through its Gigapower joint venture with BlackRock.
- AT&T has also quietly increased the availability of its Internet Air FWA (Fixed Wireless Access) services to over 130 markets, as It potentially positions the service to move beyond just a means of capturing existing DSL subscribers.
These deals follow on the heels of T-Mobile’s proposed acquisition of Lumos Networks, which is slated to pass 3.5 million homes with fiber by the end of 2028. Under the terms of the deal, Lumos will transition to a wholesale model with T-Mobile as the anchor ISP. This is exactly the type of arrangement T-Mobile has established with some of its other infrastructure partners. However, with its partial ownership of Lumos, T-Mobile can presumably generate better returns and healthier margins from its broadband service offerings. The joint venture also is consistent with T-Mobile’s goal of expanding its market presence and footprint without expending a significant amount of capital. In fact, if you take the $1.4B that T-Mobile will ultimately invest in Lumos as it increases its homes passed from 320K to 3.5M by the end of 2028, T-Mobile’s cost per home passed ends up being somewhat less than $500.
That $500 per home passed figure could be even lower should Lumos continue to secure additional American Rescue Plan Act (ARPA) Capital Project Fund grants as well as a portion of the $3.6 B in aggregate BEAD (Broadband Equity, Access, and Development) funding across North Carolina, South Carolina, and Virginia.
The primary reason for T-Mobile’s push into both direct fiber network ownership and partnerships with open access fiber providers is that the operator has over 1 million customers on a waiting list for its fixed wireless service. These customers can’t be served because they are in markets where T-Mobile does not have enough 5G capacity to serve them. As T-Mobile expands the reach of its fiber offering, it can not only provide service to these customers but also existing FWA subscribers. Once an FWA subscriber switches to T-Mobile Fiber, that opens the spectrum for additional FWA subscribers.
US telcos are moving quickly to expand the reach of their fiber, fixed wireless, and ISP services to complement their nationwide mobile networks because they smell blood among the largest cable operators. Telcos are disrupting the broadband market faster and more efficiently right now—a disruption that could very well be amplified by Federal and State subsidies.
With the rollout of 5G networks having had little impact on the profitability of mobile services, fixed wireless has emerged as the most successful use case for mobile network operators (MNOs) can monetize their excess 5G capacity. FWA’s timing couldn’t have been better, with inflation having increased from 2021 on, pushing subscribers to seek out more affordable—but still high quality—broadband service offerings. FWA hit the market providing a powerful combination of affordability, speed, and availability.
The success of FWA combined with overall fiber network expansions has given telcos a potent tool for not only the convergence of mobile and fixed broadband services but also the emergence of these services being offered on an almost nationwide basis. It’s pretty simple math. If you can offer a product or service to a larger number of end customers, the higher the likelihood of continued net subscriber additions, all other things being equal.
Even in markets where there is overlap between fixed wireless and that MNO’s own (or marketed) fiber broadband services, there isn’t really a danger of cannibalization, because the two services will very likely address very different subscribers. As the telcos’ ARPU (average revenue per unit) results have shown, subscribers are willing to pay more for fiber-based connectivity. In 2Q24, for example, AT&T announced that its fiber broadband ARPU is $69 and that the mix shift of its subscribers to fiber has pushed overall broadband ARPU up to $66.17, representing a 6% increase from 2Q23.
Meanwhile, in the second quarter, T-Mobile reported an ARPA figure of $142.54, which was up from $138.94 in 2Q23. Partially fueling that increase was an increase in the number of customers per account, due largely to the adoption of FWA services. Remember, T-Mobile prices and treats its FWA offering as an additional line of service, making it very simple to add to an existing T-Mobile account.
With a starting price point of $50 and typical download speeds ranging from 33-182 Mbps and upload speeds of 6-23 Mbps, T-Mobile is clearly targeting the low-mid cable broadband tiers—and having a great deal of success in converting those subscribers.
Going forward, the 1-2 punch of FWA and fiber will allow the largest telcos to have substantially larger broadband footprints than their cable competitors. Combine that with growing ISP relationships with open access providers and these telcos can expand their footprint and potential customer base further. And by expanding further, we don’t just mean total number of homes passed, but also businesses, enterprises, MDUs (multi-dwelling units), and data centers. Fiber footprint is as much about total route miles as it is about total passings. And those total route miles are, once again, increasing in value, after a prolonged slump.
For cable operators to successfully respond, consolidation likely has to be back on the table. The name of the game in the US right now is how to expand the addressable market of subscribers or risk being limited to existing geographic serving areas. Beyond that, continuing to focus on the aggressive bundling of converged services, which certainly has paid dividends in the form of new mobile subscribers.
Beyond that, being able to get to market quickly in new serving areas will be critical. In this time of frenzied buildouts and expansions, the importance of the first mover advantage can not be overstated.
The push and pull of broadband and wireless subscribers isn’t expected to slow down anytime soon. Certainly, with inflation continuing to put pressure on household budgets, consumers are going to be focused on keeping their communications costs low and looking for value wherever they can find it. That means we are returning to an environment where subscribers take advantage of introductory pricing on services only to switch providers to extend that introductory pricing once the initial offer expires. That shifting and its expected downward pressure on residential ARPU will likely be countered by increasing ARPUs at some providers as they move existing DSL customers to fiber or, in the case of cable operators, move customers to multi-gigabit tiers.
The US broadband market is definitely in for a wild ride over the next few years as the competitive landscape changes across many markets. The net result is certain to be shifts in market share and ebbs and flows in net subscriber additions depending on consumer sentiment. One thing that will remain constant is that value and reliability will remain key components of any subscription decision. The providers that deliver on that consistently will ultimately be the winners.

Nvidia enters Data Center Ethernet market with its Spectrum-X networking platform
Nvidia is planning a big push into the Data Center Ethernet market. CFO Colette Kress said the Spectrum-X Ethernet-based networking solution it launched in May 2023 is “well on track to begin a multi-billion-dollar product line within a year.” The Spectrum-X platform includes: Ethernet switches, optics, cables and network interface cards (NICs). Nvidia already has a multi-billion-dollar play in this space in the form of its Ethernet NIC product. Kress said during Nvidia’s earnings call that “hundreds of customers have already adopted the platform.” And that Nvidia plans to “launch new Spectrum-X products every year to support demand for scaling compute clusters from tens of thousands of GPUs today to millions of DPUs in the near future.”
- With Spectrum-X, Nvidia will be competing with Arista, Cisco, and Juniper at the system level along with “bare metal switches” from Taiwanese ODMs running DriveNets network cloud software.
- With respect to high performance Ethernet switching silicon, Nvidia competitors include Broadcom, Marvell, Microchip, and Cisco (which uses Silicon One internally and also sells it on the merchant semiconductor market).

…………………………………………………………………………………………………………………………………………………………………………..
In November 2023, Nvidia said it would work with Dell Technologies, Hewlett Packard Enterprise and Lenovo to incorporate Spectrum-X capabilities into their compute servers. Nvidia is now targeting tier-2 cloud service providers and enterprise customers looking for bundled solutions.
Dell’Oro Group VP Sameh Boujelbene told Fierce Network that “Nvidia is positioning Spectrum-X for AI back-end network deployments as an alternative fabric to InfiniBand. While InfiniBand currently dominates AI back-end networks with over 80% market share, Ethernet switches optimized for AI deployments have been gaining ground very quickly.” Boujelbene added Nvidia’s success with Spectrum-X thus far has largely been driven “by one major 100,000-GPU cluster, along with several smaller deployments by Cloud Service Providers.” By 2028, Boujelbene said Dell’Oro expects Ethernet switches to surpass InfiniBand for AI in the back-end network market, with revenues exceeding $10 billion.
………………………………………………………………………………………………………………………………………………………………………………
In a recent IEEE Techblog post we wrote:
While InfiniBand currently has the edge in the data center networking market, but several factors point to increased Ethernet adoption for AI clusters in the future. Recent innovations are addressing Ethernet’s shortcomings compared to InfiniBand:
- Lossless Ethernet technologies
- RDMA over Converged Ethernet (RoCE)
- Ultra Ethernet Consortium’s AI-focused specifications
Some real-world tests have shown Ethernet offering up to 10% improvement in job completion performance across all packet sizes compared to InfiniBand in complex AI training tasks. By 2028, it’s estimated that: 1] 45% of generative AI workloads will run on Ethernet (up from <20% now) and 2] 30% will run on InfiniBand (up from <20% now).

Dell’Oro: Campus Ethernet Switch Revenues dropped 23% YoY in 1Q-2024
Worldwide Campus Ethernet Switch [1.] revenues plummeted by 23% YoY in the 1st quarter of 2024 to a 2-year low, according to the Dell’Oro Group.
- The only two vendors that grew campus switch revenues year over year were Santa Clara, CA based Arista Networks and Ubiquiti [2.].
- Cisco’s campus switch revenues fell more than the worldwide average.
Note 1. With higher demand from new use cases for wired connectivity such as automation, analytics, and network visibility, and the need for new access switches to aggregate Wireless LAN access points, Dell’Oro Group is offering in-depth analysis specifically on Ethernet Switches built and optimized for deployment outside the data center, for the purpose of connecting users and things to the corporate Local Area Network (LAN).
“Basically, campus switches are really the networking gear to connect users and devices and laptops,” said Sameh Boujelbene, VP with Dell’Oro Group. “Access points are probably the number one application.”
………………………………………………………………………………………………………..
Note 2. Although headquartered in New York, NY, Ubiquiti wrote in a 2019 SEC filing:
“We use contract manufacturers, primarily located in China, Vietnam and Taiwan, to manufacture our products. Our relationships with contract manufacturers allow us to conserve working capital, reduce manufacturing costs and minimize delivery lead times while maintaining high product quality and the ability to scale quickly to handle increased order volume. Over the long term, our contract manufacturers are not required to manufacture our products for any specific period or in any specific quantity. If necessary, we expect that it would take approximately 3 to 6 months to transition manufacturing, quality assurance and shipping services to new providers.”
………………………………………………………………………………………………………………………
“Vendor backlogs of campus switch orders have now been completely run down, and the market is in a multi-quarter digestion cycle,” said Siân Morgan, Research Director at Dell’Oro Group. “The shipments of most port speeds declined, and the Average Sales Price (ASP) also dropped on a YoY basis.
“However, in 1Q 2024, Arista had its third sequential quarter of (market) share gain, growing Campus Switch sales to large enterprises.
On the downside, Cisco’s Campus Switch shipments contracted sharply. This reduction contrasts with their shipments in 2023, when Cisco opened the “floodgate” for Catalyst and Meraki port shipments which had been on backorder,” added Morgan.
Additional highlights from the 1Q 2024 Ethernet Switch – Campus Report:
- The contraction in campus switch sales was broad-based across all regions, with the exception of Central America-Latin America (CALA).
- Some vendors bucked the price trend and were able to grow port ASPs thanks to richer product mixes.
- 5/5.0 Gbps switch ports are expected to return to growth as shipments of Wi-Fi 7 Access Points accelerate.

Highlights of IEEE Triple Milestone Event – May 20, 2024 at CHM
Three very significant IEEE Milestones were celebrated May 20th at the Computer History Museum (CHM) in Mt. View, CA. They were as follows:
- Google’s PageRank Algorithm and the Birth of Google. The PageRank Algorithm shaped our access to digital content and put Google on the map as an established web search company.
- The 1974 IEEE Computer Society paper on TCP (“Transmission Control Protocol (TCP) Enables the Internet”) authored by Vint Cerf and Bob Kahn.
- The IEEE 802 LAN/MAN Standards Committee which generated and maintains the standards for IEEE 802.3 (Ethernet), 802.11 (Wi-Fi®), 802.15 (early Bluetooth), among others.
Among newer and important IEEE 802 projects:
- IEEE 802.1 Time Sensitive Networks Task Group provides standards for deterministic connectivity through IEEE 802 networks (i.e., guaranteed packet transport with bounded latency, low packet delay variation, and low packet loss). It’s being used at CERN’s Large Hadron Collider (LHC) – the world’s largest and most powerful particle accelerator.
- IEEE 802.19 Wireless Coexistence Working Group deals with coexistence between unlicensed wireless networks. Many of the IEEE 802 wireless standards use unlicensed spectrum and hence need to address the issue of coexistence when operating in the same unlicensed frequency band in the same location.
In addition, four other ground breaking IEEE milestones were briefly discussed:
- Development of the Commercial Laser Printer, 1971-1977 Ron Rider, VP of Digital Imaging (retired), Xerox PARC
- Xerox Alto Establishes Personal Networked Computing, 1972-1983 John Shoch, Office Systems Division President (retired), Xerox PARC
- Ethernet Local Area Network (LAN), 1973-1985.
- ALOHAnet Packet Radio Data Network, 1971 Bob Metcalfe, Co-Inventor of Ethernet at Xerox PARC and Frank Kuo, University of Hawaii.
Dedication of the above 4 Milestones:
The first three milestones were dedicated at SRI PARC on Friday, May 17th. The fourth milestone ALOHAnet led directly to the development of Ethernet.

Of particular significance to IEEE Techblog readers:
- Vint Cerf, who co-authored the TCP (Transmission Control Protocol) paper with Bob Kahn and is often called a “father of the Internet,” described the history of the Internet. He said that Arpanet and ALOHAnet led the way to the Internet, which is celebrating its 50th anniversary this month with the IEEE Computer Society’s publication of the TCP paper.
- In addition to new enabling technologies (e.g. hollow core fiber and LEO satellite connectivity) Vint said we need new policies for economic, social and legal frameworks to make the Internet safer and more secure. Also, to hold bad actors responsible for malicious behavior. The Internet Society and others need to educate regulators to make these types of changes.
- Past and present executives of the IEEE 802 LAN/MAN Standards Committee discussed the success of Ethernet (802.3), Wi-Fi (IEEE 802.11), Wireless Specialty Networks (IEEE 802.15), MAC Bridging (IEEE 802.1) which were developed by IEEE 802 LMSC. The purpose and role of the Radio Regulatory Technical Advisory Group, which supports the work of various 802 wireless standards, was also explained.
- Ethernet co-inventor Bob Metcalfe provided a genesis of Ethernet which he co-invented with David Boggs while at Xerox in 1973. Working on Project MAC at MIT in 1970, Metcalfe used the Arpanet to connect dumb terminals to time shared computers. After he joined Xerox PARC, Bob read a paper about the ALOHAnet network at the University of Hawaii by Norm Abramson and was so intrigued that he visited there for one month to gain a deeper understanding of that innovative radio packet network. It used randomized retransmissions after a collision. The Ethernet MAC protocol (Carrier Sense Multiple Access with Collision Detection) he developed used similar ALOHAnet concepts. At 2.94 Mb/sec, the first Ethernet was 306.25 times faster than ALOHAnet (9.6 Kb/sec). That’s because it ran on 0.5 inch coaxial cable rather than radio airwaves. The 2.94 Mb/sec rate (vs 3 Mb/sec) was chosen due to the size limitation of the Ethernet circuit card which could not include a 3 Mb/sec crystal oscillator. That first 1973 version of Ethernet was used at Xerox to enable Alto GUI workstations (predecessor to the PC) to share a networked laser printer and for Xerox PARC engineers to communicate via in house email.
Addendum: Metcalfe did not mention that the hardware for the 10M b/sec version of Ethernet, which in 1985 became the IEEE 802.3 10Base5 CSMA/CD standard, was designed at Xerox by Robert Garner and Ron Crane, RIP.
In April 2022, IEEE SV Tech History committee (founded and initially chaired by this author 2013-2015), presented an event on the history of Ethernet at Xerox. The event description is here and the video is here. Unsung Hero of Ethernet Geoff Thompson moderated this superb panel session. It was originated by this author to provide well deserved recognition for another Unsung Hero- the late and great Ron Crane who (with Robert Garner) co-designed Xerox’s 10 Mb/sec Ethernet circuit card for the Xerox Star workstation as well as 3COMs breakout product – Etherlink circuit card (product # 3C100) for the IBM PC, which shipped in September 1982.

Ethernet Alliance multi-vendor interoperability demo (10GbE to 800GbE) at OFC 2023
The Ethernet Alliance, a global consortium dedicated to progressing Ethernet technologies (albeit, only the MAC frame format is left from the original 10BaseT Ethernet standard), this week exhibited a multivendor interoperability demonstration at the OFC 2023 conference and exhibition in San Diego, CA.
–>Please see References 1. and 2. below for the detailed multi-vendor interoperability demo diagrams.
Featuring 18 different participating member companies, the Ethernet Alliance interoperability demo spans diverse Ethernet technologies ranging from 10 Gigabit Ethernet to 800GbE. The interoperability display features a live network between the booths of Ethernet Alliance and the Optical Internetworking Forum, Exfo, Spirent Communications, and Viavi Solutions.
The network leverages single-mode optical fibers with high-speed traffic originating from an array of switches, routers, interconnects, including copper and optical cables. It also employs various interconnects using multiple pluggable form factors such as OSFP, QSFP-DD, QSFP, and SFP, and multiple interface types including OIF 400ZR, OpenZR+ MSA 400ZR+, and 800G-ETC-CR8.
The Ethernet Alliance also spent time highlighting its roadmap, which sees continued advancement in the speed, reliability, and use cases for the networking protocol across multiple sectors. The goal of the organization is not to invent new standards, but rather to help foster their adoption and deployment in an interoperable approach.

“We’re now at the half-century mark, and Ethernet’s star continues to rise. As a profoundly resilient technology that’s getting progressively faster, it is an innovation engine that drives market diversification and fuels business growth. If you think about the journey from invention to deployment, what we do is we try to show that the technology does work and it is mature enough that it can be deployed,” said Peter Jones, chairman, Ethernet Alliance.
In the enterprise market, demand for 10 GbE-based Ethernet remains strong and there is also some growth for 25 GbE, which is intended more for servers. Ethernet also has 100 GbE and 400 GbE speeds to support larger enterprise and campus needs.
Network operators are always looking for more network capacity and speed and to that end 800 GbE and soon 1.6 Tb/s Ethernet (TbE) will fit the bill.
Jones said that in the early days, the goal for each new set of specifications was to provide 10-times the speed, at only three-times the price of the existing specification. Over time what has occurred is the standards have not just been racing forward to ever faster speeds, but rather are being tailored to meet the price and performance characteristics that a given use case requires.
For example, work is ongoing to help bring Ethernet into more industrial use cases as a solution for serial connections. Ethernet is also increasingly finding its way into automotive use cases as modern vehicles rely on growing levels of compute capacity to operate and communicate.
The Ethernet Alliance is also working on certification efforts for Power-over-Ethernet (PoE). While there have long been PoE standards, there hasn’t been a full-scale certification effort in the same way that there is for Wi-Fi in the wireless world. Jones said that while PoE mostly works today, there have been some instances of vendor technologies that weren’t interoperable.
“We really want people to be able to buy certified devices because we want to preserve the idea that Ethernet just works and we were starting to see that breaking down with PoE,” Jones said. “Ethernet is the most important technology that no one ever sees. Very few people that use the internet understand that Ethernet is the key part of it,” he added.
“One of OFC’s highlights was live interoperability demonstrations from leading optics companies running over OFCnet,” said OFC chairs Chris Cole, Coherent Corporation; Ramon Casellas, Centre Tecnològic de Telecomunicacions de Catalunya; and Ming-Jun Li, Corning Incorporated.
