Single Pair Ethernet Technology

Single Pair Ethernet (SPE) enables flexible, transparent sensor-to-cloud connectivity for industrial and smart building environments while eliminating the space, distance, bandwidth and power limitations associated with either traditional multi-pair Ethernet, industrial fieldbus or sensor systems and cabling.

SPE uses only one pair of copper wires to transmit data at speeds between 10 Mb/s and 10 Gb/s while also providing power—all while establishing seamless Ethernet connectivity from the sensor to the cloud (without proprietary systems and gateways) and offering a reach of up to 1,000 m.

This helps discrete manufacturers, process industry plants, logistics centers, mass transportation rolling stock and stations, and commercial buildings take advantage of IIoT and innovations like predictive maintenance, which rely on high volumes of data and AI-based analytics.

Furthermore, it facilitates fast commissioning and simplifies monitoring and maintenance tasks, making all devices visible and accessible from the engineering and operations terminals connected to the same network, establishing IT/OT convergence.

Belden has a strong bench of experts who understand not only SPE, but also the unwavering demands of rugged industrial environments, from automotive manufacturing environments to process industry plants.

We’re actively engaged in the SPE Industrial Partner Network to accelerate the adoption of next-gen OT and IIoT connectivity using Ethernet instead of proprietary communication technologies. We’re also a member of the Single Pair Ethernet Consortium (SPEC), working alongside the Telecommunications Industry Association (TIA) for the same purpose.
