In the world of the Industrial Internet of Things (IIoT), we've spent years talking about big data and the cloud. On the ground, how do you get high-speed Ethernet that reduces cabling volume, connector size, and installation complexity?

Single Pair Ethernet (SPE) is a true game-changer, slimming down infrastructure by running data and power (SPoE) over only two wires instead of the traditional eight. SPE does not replace traditional Ethernet backbones. Instead, it complements them by extending Ethernet to the edge while relying on standard Ethernet aggregation layers.

Volktek is using the terminal block for the SPE connectivity. Since the market has not yet converged on a commonly used connector type, using terminal block connectors allows for more flexibility for connecting current and future SPE devices. This makes field installation much more intuitive and allows for seamless integration without overhauling current setups.

Why Single Pair Ethernet (SPE) is a Game Changer

Cost Savings

SPE uses about 50% less copper. Because Volktek uses terminal blocks, you don't need to buy expensive, pre-terminated patch cords, and existing cabling can possibly be reused.

Continuous Ethernet Connectivity

SPE enables direct communication with field devices via IP addresses, effectively eliminating the need for complex protocol gateways. By leveraging standard Ethernet security features, it also ensures robust protection against evolving IT threats.

Serious Distance

While standard Ethernet taps out at 100 meters, Volktek's SPE solutions can reach up to 1,000 meters, covering the distance requirements of most fieldbus protocols. That's a kilometer of connectivity on a single pair of wires.

High-speed Field Level Communication

SPE provides a 10–100x increase in bandwidth, enabling high-frequency data acquisition while facilitating more powerful centralized management across the industrial network.

Real-World Applications: Where SPE Shines

Smart Buildings

Modern HVAC and fire safety systems require hundreds of sensors tucked away in ceilings and walls. Traditional cabling is often too heavy and bulky for these tight runs. With Volktek's SPE switches, you can power and connect a smoke detector or thermostat up to 1,000 meters away using a single, lightweight cable.

Industrial Automation

SPE streamlines machine health monitoring by providing high-speed connectivity to compact edge sensors. By monitoring a 3-axis accelerometer, the system precisely detects vibrations and imbalance in real time. This seamless flow of diagnostic data enables preventive maintenance, allowing operators to address mechanical issues before they lead to costly downtime.

Greenhouse & Agricultural Tech

Monitoring soil moisture or CO2 levels across acres of land is a logistical nightmare if you have to install repeaters every 100 meters. Because Volktek's SPE reaches 1,000 meters, a single central hub can collect data from the entire facility, simplifying the network and reducing hardware costs.

Logistics & Warehousing

In automated warehouses, cables need to move with robotic arms and snake through narrow conveyor tracks. The slim profile of SPE cable makes it much easier to install in moving parts. If a cable does break, the terminal block design allows for a quick on-site repair, keeping downtime to an absolute minimum.
