Single Pair Ethernet (SPE) – Compact Network Solutions for Industry 4.0 and IIoT
One Pair of Wires – An Infinite Number of Applications
Single Pair Ethernet (SPE) reduces data transmission to a single twisted pair of wires and enables:
– Data rates of up to 1 Gbps
– Transmission distances of up to 1,000 meters
– Power over Data Line (PoDL) and hybrid installations using the same cable
– Multidrop networks for flexible topologies
This significantly reduces cabling effort, and in many cases, existing infrastructure can continueto be used.
SPE establishes unified, Ethernet-based communication from the sensor to the cloud and is considered a key technology for Robotics, Industry 4.0 and IIoT. Benefits such as space, weight, and costsavings make SPE ideal for industrial and commercial applications.
With the upcoming IEC 63171-7 ED2 standard, future-proof solutions are emerging that optimally prepare networks for the requirements of Industry 4.0 and IIoT.
Single Pair Ethernet (SPE) simplifies data transmission by using just a single wire pair for communication. While traditional Ethernet often reaches its limits on the field level – due to complex installation, limited range, or lack of robustness – SPE provides a streamlined, efficient, and reliable alternative.
Benefits of Single Pair Ethernet (SPE)
– Unified communication: End-to-end Ethernet-based networking from the sensor to the cloud
– Standardized & future-proof: Based on international standards (IEC 63171-7 ED2)
– Efficient infrastructure: Reduced cabling effort; existing installations can often be reused
– Extended range: Data transmission up to 1,000 m
– High data rates: Supporting speeds up to 1 Gbps
– Power over Data Line (PoDL): Simultaneous transmission of data and power
– Resource-saving design: Lower weight, smaller bend radius, and compact dimensions
SPE creates a simplified infrastructure and is regarded as a key technology for Industry 4.0, Roboticsand the Industrial Internet of Things (IIoT).
