Phoenix Contact: Ethernet communication become easier

With the advent of the digital era, traditional Ethernet has gradually shown some difficulties when facing growing network requirements and complex application scenarios.

For example, traditional Ethernet uses four-core or eight-core twisted pairs for data transmission, and the transmission distance is generally limited to less than 100 meters. The deployment cost of manpower and material resources is high. At the same time, with the advancement and innovation of technology, equipment miniaturization is also an obvious trend in the current development of science and technology. More and more devices tend to be smaller and more compact in size, and the trend of device miniaturization drives the miniaturization of device interfaces. Traditional Ethernet interfaces usually use larger RJ-45 connectors, which are larger in size and difficult to meet the needs of device miniaturization.


The emergence of SPE (Single Pair Ethernet) technology has broken the limitations of traditional Ethernet in terms of high wiring costs, limited communication distance, interface size and equipment miniaturization. SPE (Single Pair Ethernet) is a network technology used for data communication. It transmits data by using only a pair of cables. The SPE (Single Pair Ethernet) standard defines the specifications of the physical layer and data link layer, such as wire Cables, connectors and signal transmission, etc. However, the Ethernet protocol is still used in the network layer, transport layer and application layer. Therefore, SPE (Single Pair Ethernet) still follows the communication principles and protocol specifications of Ethernet.

By improving the physical layer, SPE (Single Pair Ethernet) technology provides a more efficient, flexible and economical data communication solution while maintaining interoperability with traditional Ethernet. This allows users to enjoy the advantages of SPE (Single Pair Ethernet) technology without changing the existing network architecture and communication protocols.

In addition to transmitting data through Ethernet, SPE (Single Pair Ethernet) technology can also provide power to terminal devices at the same time. Power over data line (PoDL) can deliver up to 50 W of effective output.

SPE (Single Pair Ethernet), as an Ethernet-based technical standard, follows the relevant specifications in the IEEE 802.3 standard. Among them, the IEEE 802.3bu and IEEE 802.3cg standards define different power levels for power supply through data lines. Relying on SPE (Single Pair Ethernet) technology, data transmission cables can be used to power sensors or actuators within a range of 1,000 meters.
