Single Pair Ethernet components

Climate data & Ethernet on SPE


In contrast to classic Ethernet, transmission via Single Pair Ethernet only requires a single wire pair. SPE installations therefore require less material than previous field communication. The SPE standard enables standardized data communication across all company levels, from the sensor to the cloud, as well as the power supply of sensors via SPoE. SPE can also be used to bridge very long distances, as SPE cables transmit data reliably over distances of up to 1000 meters.
