A cable is an awkward candidate for a starring role. It has no interface to admire, no conversational talents, and very little to say at a dinner party. Yet Dan Miranda has spent more than two decades building a business around the connections that let other people's technology perform. Proficium, which he founded in 2003, now supplies the optical networking and cabling used in AI and hyperscale data centers. The software may get the applause. Somewhere, a connection still has to work.
Miranda's story has a useful complication: the company still carries his founding imprint, but the chief executive's chair belongs to someone else. He is now president and founder. Todd Swanson became CEO in August 2024. That change followed a growth investment from Mill Point Capital earlier the same year. Read together, those events describe a founder moving into a different chapter while the business he started expands its ambitions.
There is something appealingly concrete about this career. Its central objects can be ordered, manufactured, connected and tested. For all the grand language surrounding artificial intelligence, Miranda's business occupies a world of physical specifications. The distance between two pieces of equipment matters. So does whether the equipment agrees to communicate. A grand vision is welcome; a compatible connector is also helpful.
Sixteen years before the AI clusters
The first date to keep in mind is 2003. Proficium began then, years before its present association with AI networking. The second is 2019, when the company says it started supplying high-bandwidth networking solutions to AI and machine-learning clusters. Sixteen years separate those milestones. The chronology gives Miranda's career its shape: an established connectivity business found itself serving a newer computing workload.
That distinction matters when considering what a founder has built. A company can enter a fashionable market through a new name, a new pitch or a long accumulation of relevant work. Proficium's history places its AI activity within a longer operating life. The calendar alone cannot explain every decision along the way. It does establish that the business preceded this particular application by a considerable stretch.
Today, the company's range includes fiber and copper cable assemblies, optical transceivers and cable-management products. These are the parts that connect a computing installation together. Miranda's work belongs to that practical layer of the industry, where a product's usefulness depends on how it behaves among other products. The relationship between the parts is the business.
On LinkedIn, Miranda has also shared a Proficium opening for an inside sales representative in Union City. It is a small public detail, but one tied directly to the work of maintaining a business. Products need people who can explain them, orders need attention, and a growing customer base needs support. Alongside the larger milestones, recruiting offers a glimpse of the everyday organizational work that continues between announcements.
The year the company changed shape
On March 27, 2024, Mill Point Capital announced its partnership with Proficium. Miranda was identified as founder and CEO, and the announcement said he would continue leading the company. The investment brought a new institutional partner into the story after more than twenty years of operations. It also put a clearer public marker on Proficium's next phase.
Miranda framed the opportunity around demand for data-center capacity. His language included employees and the company, rather than a personal victory lap. The announcement was about taking advantage of the market ahead with a partner's support. It is a business ambition with a fairly specific address: the infrastructure needed to accommodate more computing.
“Our partnership with Mill Point comes at an exciting time”
Dan Miranda, March 2024
D.A. Davidson acted as Proficium's exclusive financial adviser on the investment. Its account describes the work behind the transaction: negotiations, structuring, due diligence and resolving issues before completion. These are the less photogenic parts of a corporate milestone. They are also where an announced partnership becomes an executable arrangement. Even a business built on connections needs people to work through the paperwork.
The adviser's case study described a business serving customers worldwide and addressing overlooked needs in high-performance computing. It also anticipated strengthening management with industry veterans from Mill Point's network. That combination helps explain the significance of 2024. Capital was one part of the change; additional experience around the leadership table was another.
A founder makes room at the table
In August 2024, Proficium hired Brian Patton as chief technology officer. His assignment covered the design, development and implementation of connectivity products. Miranda's comments on the appointment emphasized the benefit to customers of Patton's optical-networking experience. The focus was technical capability, expressed through a leadership hire.
Patton had spent thirteen years as vice president of engineering at Approved Networks. Bringing that background into Proficium gave the company a senior technical leader with experience across the optical-connectivity market. For Miranda's story, the important point is the appointment itself: the founder's company was adding experienced people to carry substantial parts of the work.
Swanson joined as CEO that same month. He arrived from Intel's Silicon Photonics Product Division and had previously spent more than eighteen years at Finisar. Proficium assigned him responsibility for strategy, operations and market expansion. Miranda remained in the leadership team as president and founder. Those titles describe continuity alongside a clear change in who holds the chief executive role.
In his public assessment of Swanson's first year, Miranda credited his technical knowledge, leadership and relationships. The emphasis is revealing in a limited, practical sense: these were the qualities Miranda chose to recognize. A founder introducing a new CEO is also explaining what the organization needs from its next chapter. Here, the vocabulary stayed close to engineering, execution and customers.
Where a specification meets a working network
To understand the company Miranda founded, follow a product beyond its label. Proficium's testing operation checks connectivity products in systems from multiple equipment makers. Its lab describes work with Ethernet and InfiniBand environments and equipment from companies including Nvidia, Cisco, Arista, Juniper, Dell and Intel. Compatibility is something to examine in use.
The tests include performance, interoperability and distance. Each asks a different question. Does the component perform as intended? Does it work with the surrounding system? Does it operate over the required reach? A purchasing description may fit on a short line. Establishing that the purchase will do its job can require a much longer conversation.
There is a manufacturing counterpart to that approach. Proficium offers U.S. quick-turn production for prototypes and smaller runs, alongside contract-manufacturing relationships focused on Southeast Asia. Different orders have different constraints. A small urgent project and a larger production run do not necessarily call for the same route through a factory.
The domestic manufacturing offering explicitly acknowledges a higher cost than Southeast Asian production while emphasizing lead times and oversight. That is a more interesting trade-off than an uncomplicated promise to do everything cheaply and immediately. It describes an operating business making choices among speed, volume and cost. Miranda's company has to answer those ordinary questions even when the application carries an extraordinary amount of attention.
Faster, while keeping what already works
The product announcements of 2025 show two directions for the business. In September, Proficium announced 1.6-terabit-per-second optical transceivers and an expanded testing platform. The new VIAVI ONE LabPro ONE-1600 equipment supports analysis and traffic simulation at 800G and 1.6Tb/s. Product development and the ability to evaluate products were moving together.
In October, another announcement addressed a different concern: how to upgrade while retaining existing cabling. The company's 400G QSFP-DD Universal transceiver supports both single-mode and multimode fiber through a duplex LC connector. Its stated applications include existing multimode installations and single-mode operation over distances up to one kilometer.
Those announcements make an instructive pair. One reaches toward a higher data rate. The other accommodates infrastructure already installed. Customers can want both progress and continuity, sometimes in the same purchase order. This is the commercial territory occupied by Miranda's business: making newer requirements fit into networks that already contain a great many decisions.
The products are company achievements, developed and supported by a team. Their relevance to Miranda is the enterprise he founded and continues to help lead. A founder's story can be told through the organization taking on more specialized work, adding expertise and giving other leaders responsibility. The name on the founding chapter remains important without having to appear on every technical development.
At Proficium, the founding date, the completed investment and the leadership appointments mark different kinds of work. Miranda started the organization, led it through the partnership and remained as its leadership changed. The resulting business has responsibilities that extend across product development, manufacturing and support. Its next orders arrive in a market where the requirements keep changing, regardless of how long a supplier has been operating.
Miranda's current chapter therefore has two clocks running through it. One measures the years since 2003. The other measures a market in successive networking generations. He now holds a different title inside the company that connects those two timescales. The details remain stubbornly physical: fiber, copper, modules, testing. Even the future needs somewhere to plug in.
