SPACE-SAVING, COST-EFFECTIVE
Dacom West GmbH is placing greater emphasis on collaborating with selected international partners and is systematically expanding its portfolio in the field of industrial networking technologies.
As part of this, we are increasingly representing our Asian manufacturers Taimag Corporation, Davicom Semiconductor and WIZnet, offering their high-performance products and components for modern embedded and communication solutions.
Through these partnerships, we are able to provide our customers with innovative, readily available and cost-effective solutions for industrial networks and IoT applications.
Single Pair Ethernet (SPE) is an innovative Ethernet technology that enables data transmission and power delivery (Power over Data Line – PoDL) via a single pair of wires. Unlike traditional Ethernet standards, which require multiple wire pairs, SPE significantly reduces cabling requirements. This makes it ideal for applications where space and weight are critical factors, such as in industrial automation, building automation, the automotive sector and the IoT (Internet of Things).
An innovative SPE solution made possible by a strong partnership
TERZ Industrial Electronics is embracing Single Pair Ethernet – working with Dacom West and Taimag to deliver an innovative SPE solution.
Applications of SPE solutions
Single Pair Ethernet is ideally suited to infrastructure applications, for example in mechanical and plant engineering, process technology, building automation and other sectors.
The major advantage:
Single Pair Ethernet is environment-neutral. Field devices, sensors and actuators can be easily integrated into an existing Ethernet environment via cables and connectors. No additional gateways or interfaces are required during installation. Unlike fieldbus protocols, SPE permeates all levels of automation.
SPE is more consistent, more efficient and more cost-effective than fieldbus systems.
Advantages of Single Pair Ethernet
SPE offers a number of advantages that set it apart from conventional Ethernet technologies:
- Compact cabling: Space requirements are minimised thanks to transmission via just one pair of wires. This enables lighter and more flexible installations, which is particularly advantageous in confined or difficult to access areas.
- Cost efficiency: Fewer cables and connectors mean lower installation and material costs. Simpler network infrastructures also reduce maintenance and downtime costs.
- Longer transmission distances: SPE enables transmissions of up to 1,000 metres, which makes it particularly interesting for large industrial plants or extensive building cabling.
- Future-proof: With the ability to transmit data rates of up to 1 Gbit/s, SPE is ideally equipped for future requirements in networked systems.
- Power over Data Line (PoDL): In addition to data transmission, power can also be transmitted via the same wire pair, making additional cables superfluous and further simplifying installations.
Networked infrastructure Semiconductor components are an integral part of the intelligence of Industry 4.0
TAIMAG
These highly integrated chips offer various communication speeds in Single Pair Ethernet, such as 10/100 or Gigabit, over a single twisted-pair cable. The components combine the functionality of several discrete devices in an ultra-compact, low-power package. This makes them suitable for a wide range of industrial applications utilising the latest Ethernet technology.
DAVICOM
By developing PHY and controller solutions for Single Pair Ethernet (SPE), Davicom Semiconductors is able to tap into growing markets such as industrial automation and the IoT, offering compact, cost-effective and energy-efficient connectivity solutions. By integrating PHY and controller technologies into SPE, Davicom can offer high-speed data transmission over longer distances with reduced cabling requirements and support for Power over Data Line (PoDL).
WIZnet
This compact serial-to-Ethernet module enables the simple connection of serial devices to Single Pair Ethernet in accordance with IEEE 802.3cg (10BASE-T1L) – via a single pair of wires and over distances of up to 1.2 km. With integrated network modes (TCP server/client, UDP) and flexible configuration via AT commands or a tool, the module can be quickly integrated into existing infrastructures. It is therefore ideally suited for industrial applications seeking to migrate serial interfaces to modern SPE networks.

Origin and development of Single Pair Ethernet
The origins of Single Pair Ethernet lie in the automotive industry. With the increase in networked systems in vehicles, there was a great demand for an efficient, space-saving and robust communication solution. SPE was originally developed to network the increasing number of sensors and control units in cars.
Over time, the potential of this technology was also recognised in other areas, such as industrial automation, building automation and the networking of IoT devices. Through standardisation by organisations such as the IEEE (Institute of Electrical and Electronics Engineers), SPE has become increasingly established and is now developing into a leading communication standard for a wide range of applications.
Conclusion: The future of networking with SPE
Single Pair Ethernet offers a revolutionary opportunity to simplify and optimise the networking of devices in a wide range of industries. With fewer cables, lower costs, longer transmission distances and the simultaneous transmission of power and data, SPE is a future-proof solution that meets the requirements of modern and future networks.
