What is Single Pair Ethernet?
In this article, we will discuss Single Pair Ethernet technology. If you are interested in learning about this emerging technology, keeping reading to find out more. In the second half of this article, we will also mention the main applications and uses of Single Pair Ethernet technology.
Single Pair Ethernet Explained
Single Pair Ethernet (SPE) is a communication technology that allows you to transmit data over a single twisted pair of wires. It provides a simple, low-cost, and reliable solution for connecting devices that require Ethernet connectivity but do not require high-speed data transfer rates.
SPE supports data rates of up to 1 Gbps, and you can even use a Single Pair Ethernet for power and data transmission together meaning you can power devices over the same cable that carries data. SPE uses Power over Data Line (PoDL) technology to deliver up to 50 watts of power over a single twisted pair of wires.
Now, let's move into the next segment of this informative article, where we will mention the primary uses of Single Pair Ethernet technology.
Uses of Single Pair Ethernet Technology
- SPE is useful for connecting devices in the Internet of Things (IoT) and Industrial Internet of Things (IIoT) spaces, where the devices may be small and require less bandwidth than traditional Ethernet devices.
- SPE is also useful for industrial applications, such as process automation, where you need to connect devices in harsh environments with limited space and power. It is also suitable for automotive applications, such as in-vehicle networks, where space and weight are critical factors.
- SPE has been standardized by the IEEE (IEEE 802.3cg-2019) and is becoming increasingly popular in industrial and automotive applications, where it offers advantages such as reduced cabling and connector size, lower power consumption, and longer cable runs.
- You can also use SPE in building automation, lighting control, and other applications that require connectivity over longer distances.
As promised at the beginning of this article, we have explained what a Single Pair Ethernet technology is. So, finally, we can conclude this informative article by saying that Single Pair Ethernet provides a reliable, flexible, and cost-effective solution for connecting devices in a wide range of applications but lacks the ability to transmit data at rates higher than 1Gbs where technology is certainly heading.
Whilst suitable for applications such as in-vehicle networks, where space and weight are critical factors, it is yet to take off in traditional network applications requiring High Speed data. Four pair cabling still is the preferred cabling infrastructure for most in-building applications.
