IoT Analytics estimates that by 2025 there will be approximately 27 billion connected IoT devices. Fortunately, the bulk of these devices won’t require a lot of bandwidth or power—making single pair Ethernet an ideal solution for the sensors and actuators found in tomorrow’s building automation and manufacturing equipment and alarm systems.
Single pair Ethernet (SPE) utilizes one pair of copper wires—also referred to as “twisted pair”—to transmit data at speeds of up to 1 Gbps and deliver up to 50 watts of dc power via Power over Data Lines (PoDL). Single pair Ethernet supports low power and low data over very long distances, up to 1000 meters and higher speeds and higher power up to 40 meters.
Standard | Speed | Distance/power |
IEEE 802.3cg | 10BASE-T1S | 15 meters |
IEEE 802.3cg | 10BASE-T1L | 1,000 meters |
IEEE 802.3cg | 10BASE-T1S (multidrop) | Eight nodes, 25 meters |
IEEE 802.3bw | 100BASE-T | 40 meters |
IEEE 802.3bu | Power over Data Line (PoDL) PoE for SPE | 0.5–52 watts (multiple classes) |
One major advantage of deploying single pair Ethernet resides in how the unified communications protocol functions. This allows for the collection and sharing of sensor information. As a result, machine-to-machine communications can manipulate actuators and perform other actions in enterprise buildings and manufacturing facilities.
Through PoDL, SPE delivers continuous, reliable dc power that eliminates batteries and separate powering circuits for the device. In addition, its Ethernet connection offers data security stronger than traditional Wi-Fi or legacy wired communication protocols. And because of a compact footprint that’s 25 percent smaller than traditional four pair Ethernet, deploying SPE in retrofit environments is simple and fast.
This does not mean single pair versus four pair Ethernet requires an “either/or” decision. The two wiring options are not mutually exclusive and, in many cases, will coexist in support of multiple applications.
