What You Should Know about Single Pair Ethernet (SPE)

The latest generation of SPE offers Ethernet data transport rates of 10 Mbps, full duplex. This may not seem like much considering CAT6A can run at speeds up to 10 Gbps full duplex. Yet, in many situations, a 10 Mbps max is more than enough throughput required. Additionally, the 802.3cg Ethernet specification uses the 802.3bu standard for power transport. This is also known as power over data line — or PoDL. The PoDL standard can power compatible devices belonging to 1 of 10 different power classes that range from 0.5 to 50 W of power to the end device. In many cases, 50 W of power is more than any single device would need.
SPE also has a second benefit that will be crucial for some enterprise deployment situations. Instead of a 100-meter distance limitation for both data and power over Ethernet (PoE) that’s common in 4-pair Ethernet standards, SPE supports cable lengths for data and PoDL up to 1 KM in length.

SPE and the Future of Industrial Networking

As application areas transition to Ethernet protocols and field devices continue to require increased transmission capacities, single pair Ethernet (SPE) is becoming an attractive option. It delivers fast and gigabit Ethernet combined with power over a simple two-wire interface. In addition, SPE can be used with standard industrial grade housings designed for the harshest environments.

Single Pair Ethernet in Building Cabling

With the Internet of Things (IoT), Ethernet is now making inroads into the sensor layer of smart buildings and factories. Single Pair Ethernet offers a “lean” solution for building cabling, with smaller, lighter cables, high density connections. transition rates up to one kilometer, transmission rates to Gbit/s and remote power supply over cables.

Beyond the Smart Buildings Hype – Facilities Management Insights

Smart buildings are touted as providing more efficient buildings in terms of resource utilization, renewable resources, and energy efficiency, and as delivering improved indoor air quality (IAQ), productivity, and connectivity with the digital world. They hold out the promise of seamlessly weaving people, technology, and business into an enhanced and optimized ecosystem. Facilities managers must understand the real-world practicalities of implementing smart building technologies and systems. 

Are Utilities Ready for Smart Buildings?

One of today’s highly promising innovations in energy operations is grid-interactive efficient buildings. Referred to as GEBs, these structures are connected to the grid and draw on distributed energy sources. Among other benefits, GEBs offer hold the potential to lower property operations costs. But are utilities keeping up? A new study from the American Council for an Energy-Efficient Economy tackles that question.
