The latest Docsis® 4.0 Interop event was not just another gathering of bold innovations – it was another important step forward for this industry.
With more than 50 attendees from all over the world, the energy in the room was clear. This event was not just examining boxes to comply with the protocol; It was about pushing the boundaries of the wide range of technology and seeing what is happening when the brightest minds and the fastest modem devices are collected at Cablembs.
The Interop event, Labs, which was held on August 11-14 at the headquarters of Cablebs, gave suppliers an opportunity to verify the interim operation between the equipment designed to comply with the Docsis 4.0 specifications. It focused on three main areas: speed, stability and diverse ecosystem. Each of these ingredients directly affects the quality and reliability of the wide range of service.
Ten Modem suppliers, one goal
One of the prominent aspects of this interop was 10 of the participating modem suppliers. Each supplier brings its unique hardware improvements and software on the table, creating an environment in which innovation can flourish.
Once again, the attendance at this event was the highest so far and included three operators on hand to monitor experimental offers and share the progress of the Docsis 4.0 network.
Three suppliers – Commscope, Harmonic and Vecima – brought Docsis 4.0 to this event. Again, we saw five PHD platforms (RPD) from Calian, Commescope, Harmonic, Teleste and Vecima. Of course, the ice on the cake was the number of the Docsis 4.0 modem suppliers in the attendance – Arcadyan, ASKEY, COMPAL, Gemtek, Hitron, Sagemcom, Sercomm, Ubee, Vantiva and WNC – who have brought multiple models to the modem.
Chipmakers Broadcom and Maxlinear brought the local engineering support to their cable models, and Calian shared with test solutions.
Each resource has been aligned with one common goal: proving that Docsis 4.0 technology is not just a theoretical leap but rather a vibrant technique ready to be widespread. The inter -operating tests were not simply from passing; They were about the performance in the foreground, characterized by durability and compatibility.
And the results? Let’s just say quickly and do not start describing it.
Showstopper: 16 GB per second in the direction of the river course
If there is one one who walked everyone talking about, it was 16 GB per second in the direction of the river. Achieving this type of productivity in the laboratory environment is one thing; Show it in a multi -cooperative environment – through many suppliers – is completely something else.
This was not an isolated “best condition”. Several configurations have reached Gigabit speeds of two numbers, indicating that Docsis 4.0 technology is not just a gradual step-it is the basis for multi-part services that can compete directly with fiber.
Cooperation is the new competition
Perhaps the most inspiring part of this event was devices or speed tests – it was a culture of cooperation. Ten suppliers of a different modem met, each of them has their own market goals, to ensure that when Docsis 4.0 technology reaches this field, it will work smoothly through the ecosystem. The modem most of the Interops spent working on the three cores, which leads to the possibility of intercourse through the broader ecosystem with RPD suppliers.
This spirit of cooperation guarantees that innovation is not closed in silos. When suppliers solve the challenges of interfering operating together, operators and consumers benefit from a smoother and faster offering of the next generation services.
Additional cable models operations
With a record number of the modem in the attendance, we have launched the anticipated network maintenance tests (PNM) of the modem. More and more, the signals on the factory are the most orthopedic transmission of the OFDM and the orthogonal frequency (OffMA), which provides speeds and capabilities higher than the traditional Spring capacity modification signals (QAM).
In this interop, we performed five PNM tests on modem devices, specifically obtaining data from Docsis 4.0 modem and checking the interim operation with application programming interfaces (APIS) and with data created by the modem. This PNM data will enable the most effective operational for the central cable network, while maintaining data levels at its peak using the most effective Offdm and Offma signals.
Docsis 3.1 Plus: Beyond the Tanna word
Docsis 3.1 Plus (Docsis 3.1+) was also prominent in Interop with many models in the attendance. The jump from Docsis 3.1 to Docsis 3.1+ is about raw speed. “Plus” provides expanded support for more OffD channels, which means more power speed. More than the segments of the presentation, these developments were tested, measured and verified in actual time.
Operators already discuss how these capabilities can correspond to their network development plans. With cost efficiency to take advantage of the current HFC factory and the performance benefits offered, Docsis 3.1+ back as a convincing strategy for rapid spread on a large scale.
What next
With the success of this Interop-INTEROP, the stage was set to achieve more ambitious goals. The industry now has evidence that multi -sellers Docsis 4.0 systems can be presented and played together. The following steps may include improving fixed programs to improve efficiency and start the deportation path towards Docsis 4.0 technology.
There are a lot of moving parts in this trading, but there is one certain thing: a 16GB teacher will be remembered not only for the number but what it represents – the moment when the industry saw the future of HFC networks and realized that it was already within reach.
This was not just an event – it was a standard for the future of the wide domain industry. With a standard presence, the participation of the diverse sellers and the real world’s evidence of the UCSIS 4.0 capabilities, the path to the wide range was not more clear.
There is scheduled to be Docsis 4.0 Interop for October 20 in Cablelabs. Think of joining us to see the capabilities of speed and service directly!

There is still time to join us at SCTE Techexpo25, September 29 – October. 1, 2025, in Washington, DC, Cablebs member employees are qualified to receive a full pass. Record today if you don’t yet!
If you are preparing, plan to attend “Self -recovery Networks: The New Borders of Document Operations” on Monday, September 29. In this session, my colleagues at Cablebs can join a conversation on how PNM has personal file management applications (PMA), which can create smart network technologies and exchange them on automatic performance.
