Therefore, the increasing demand for high-speed broadband is driving the growth of the data-over-cable service interface specifications 4 remote-physical layer market.

Major companies operating in the data-over-cable service interface specifications 4 remote-physical layer market are focusing on advancing innovative solutions, such as DOCSIS 4.0-capable nodes, to support cloud-native network management and open interfaces that accelerate automation and vendor interoperability. DOCSIS 4.0-capable nodes are network devices in hybrid fiber-coaxial systems that enable multigigabit symmetrical speeds and low-latency data transmission by processing PHY layer functions closer to the network edge while remaining compatible with existing customer equipment. For example, in October 2023, ATX Networks Corp., a Canada-based telecommunications company, launched the GigaXtend GS7 1.8 GHz Node, a DOCSIS 4.0-capable successor to the discontinued Cisco GS7000 Node platform. This new node allows cable operators to upgrade existing HFC networks cost-effectively by supporting a wider 1.8 GHz spectrum for enhanced upstream and symmetrical broadband services. It retains the familiar GS7000 form factor and is backward compatible with existing hardware, enabling easy field upgrades without major infrastructure changes. The GS7 also supports integration with third-party Remote PHY Devices and fiber modules, simplifying next-generation network deployments while protecting prior investments.

In July 2025, Teleste Corporation, a Finland-based provider of broadband network solutions including DOCSIS 4 Remote-PHY, partnered with VodafoneZiggo to upgrade next-generation DOCSIS 4 capabilities using Teleste’s 1.8 GHz broadband technology. This collaboration aims to transform the broadband landscape by enabling faster, more reliable DOCSIS 4 internet access across the Netherlands through deployment of Teleste’s advanced 1.8 GHz technology, improving customer experience and future-proofing the network for the next decade. VodafoneZiggo is a Netherlands-based provider of cable broadband services.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the information technology sector, particularly in hardware manufacturing, data infrastructure, and software deployment. Higher duties on imported semiconductors, circuit boards, and networking equipment have raised production and operational costs for tech firms, cloud service providers, and data centers. Companies relying on globally sourced components for laptops, servers, and consumer electronics are facing longer lead times and increased pricing pressures. In parallel, tariffs on specialized software tools and retaliatory measures from key international markets have disrupted global IT supply chains and reduced overseas demand for U.S.-developed technologies. To navigate these challenges, the sector is accelerating investments in domestic chip fabrication, diversifying supplier bases, and adopting AI-driven automation to enhance operational resilience and cost efficiency.
