Single Pair Ethernet Market size was valued at US$ 2.88 billion in 2024 and is expected to reach US$ 7.20 billion by 2031; it is estimated to record a CAGR of 14.3% from 2025 to 2031.

The Single Pair Ethernet Market is segmented into 5 major regions: North America, Europe, Asia Pacific, Middle East and Africa, South America. Asia Pacific dominated the single pair Ethernet market in 2024. Europe is the second-largest contributor to the global single pair Ethernet market, followed by North America.

The Single pair Ethernet market growth in Asia Pacific is driven by rapid industrialization, widespread adoption of Industry 4.0 technologies, and investments in smart infrastructure in countries such as China, Japan, India, South Korea, and Australia. The expansion of industrial automation, smart grids, and automotive sectors, especially the rise in electric vehicle production and industrial robotics deployment, fuels demand for SPE technology. SPE's advantages of simplified cabling, power over data line (PoDL), and cost-effectiveness are highly valued in manufacturing, energy management, and building automation. Government incentives, R&D activities, and strategic partnerships among technology providers accelerate SPE adoption across the region. The presence of major automotive manufacturers and the increase in industrial robot installations underscore SPE's critical role in advancing connectivity and automation in the region.

China, South Korea, India, and Japan are among the world's largest automobile manufacturers. APAC has the presence of the largest automotive manufacturers, such as Toyota, Suzuki, Hyundai-Kia, Honda, Nissan, Tata Motors Limited, Mitsubishi, and Lexus. Automotive giants have announced plans to expand their electric vehicle product portfolios. In December 2021, Toyota announced its plans to launch 30 electric cars by 2030. Honda has announced its intention to sell only EVs or fuel-cell vehicles by 2040. Hyundai announced the launch of 17 new EV models by 2030.

Single Pair Ethernet Market Trend: The increasing adoption of Power over Data Line (PoDL) capabilities is anticipated to be a significant trend in the Single Pair Ethernet (SPE) market. PoDL allows the simultaneous transmission of power and data over a single pair of wires, providing several advantages across various industries. PoDL enables the transmission of power to connect devices without the need for a separate power cable. This efficiency is particularly valuable in applications where simplified cabling and reduced installation complexity are essential. For example, in industrial settings, PoDL can power sensors, actuators, and other devices, streamlining the deployment of automation systems. PoDL enables devices to receive power and data through a single cable, providing flexibility in device placement. This flexibility is advantageous in scenarios where devices need to be deployed in locations that are challenging to reach with separate power and data lines. For instance, in building automation, PoDL can power and connect sensors or actuators in locations that are difficult to access with traditional cabling methods. As industries evolve and adopt more power-hungry devices, PoDL-equipped SPE systems can scale to meet increasing power demands. Thus, the increasing adoption of PoDL capabilities is offering efficiency, flexibility, and cost savings across various industries and applications. The combination of data and power delivery in a single cable aligns with the evolving requirements of modern connectivity solutions.
