What is single pair Ethernet?

Single Pair Ethernet (SPE) describes the transmission of Ethernet via only one pair of copper wires

In addition to data transmission via Ethernet, SPE also enables simultaneous power supply to end devices via PoDL – Power over Data Line.

Traditionally two pairs of copper wires were necessary for Fast Ethernet (100MB) or four pairs of copper wires for Gigabit Ethernet. “Example Cat6A Cable”

Now Single-Pair Ethernet “SPE” is represented by a new group of IEEE 802.3 standard can run cable up to 100 meters for 100 Megabit and 40 meters for 1 Gigabits

SPE now opens up completely new possibilities and fields of application for industrial Ethernet.
