Single Pair Ethernet (SPE)

Dacom West GmbH is proud to be a new member of the Single Pair Ethernet System Alliance.
This decision was made deliberately to strengthen our position in the field of industrial network technologies and at the same time to actively participate in the further development of future-orientated communication solutions. The reasons for joining the SPE System Alliance are manifold and the expectations we have of this partnership are high.

Single Pair Ethernet (SPE) is an innovative Ethernet technology that enables data transmission and power supply (Power over Data Line - PoDL) via a single pair of wires. In contrast to traditional Ethernet standards, which require multiple wire pairs, SPE significantly reduces the amount of cabling required. This makes it ideal for applications where space and weight play a role, such as in industrial automation, building automation, the automotive industry and the IoT (Internet of Things).

Application areas for SPE solutions

Single Pair Ethernet is ideal for infrastructure applications, for example in mechanical and plant engineering, process technology, building automation and other areas.

The big 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. Additional gateways and interfaces are not required during installation. Unlike fieldbus protocols, the S penetrates all automation levels.

SPE is more consistent, efficient and 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

We introduce:
TAIMAG

The highly integrated chips offer different communication speeds in Single Pair Ethernet such as 10/100 or Gigabit via a single twisted pair cable. The components combine the functionality of several discrete devices in an ultra-small housing with low energy consumption. This makes them suitable for many different industrial applications using the latest Ethernet technology.

We introduce:
DAVICOM

By developing PHY and controller solutions for Single Pair Ethernet (SPE), Davicom Semiconductors can tap into growing markets such as industrial automation and IoT and offer 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).

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.
