Single Pair Ethernet (SPE) Extending Ethernet to the Industrial Edge
Why Single Pair Ethernet?
SPE is the evolution of Ethernet physical layer technology optimized for long reach, simplicity, and power delivery.
From Legacy to IP
Replace fieldbus and serial communication with standard IP Ethernet.
Simplify Infrastructure
Use a single twisted par for data and power transmission.
Long Distance
Reach up to 1,000 meters without intermediate switches or repeaters.
Power over Data Line (PoDL)
Deliver power up to 52W with safety and reliability.
Lower Cost
Reuse existing cables and reduce installation complexity,
The SPE Family and 10BASE-T1L
SPE is defined in IEEE 802.3 and includes multiple PHY standards to address different application needs.
