Direct integration of modern sensors and field devices: The Managed and Unmanaged Switches for Single Pair Ethernet and SPE-capable Media Converters enable end-to-end Ethernet communication right up to the cloud. Additional gateways or complex subsystems are not required. The devices can be used universally with all Ethernet and IP-based protocols. In addition to the transmission of data, the end devices are optimally supplied with power from the devices via Power over Dataline (PoDL). Single Pair Ethernet fulfils the requirements for a future-proof network infrastructure.

For the first time, sensors with a single-pair Ethernet interface enable end-to-end Ethernet communication from the field level, where the sensors are installed, to the cloud. In the networked Ethernet topology, all network applications with the appropriate authorisation can access the high-precision sensor values in real time. In industrial applications based on the automation pyramid, for example, the measured values from the SPE sensors can be used consistently at all levels. With these sensors, the 10BASE-T1L technology used also ensures the required power supply to the sensor via the two-wire data cable by means of “Power over DataLine” (PoDL). No additional supply cable needs to be installed. In addition, 10BASE-T1L enables cable distances of up to 1000 metres in the application.

• Semiconductor products provide the electrical interface to SPE connectors and cables. They implement the physical layer of the ISO Communications reference model. They prepare the bits that make up an Ethernet frame so they can be placed on a single balanced pair of wires that take them to other network participants.
• SPE semiconductor products conform to standards from the Institute of Electrical and Electronic Engineers (IEEE) that define how Ethernet works. There are several standards that define networks running at different speeds.

• Semiconductors products that implement SPE can perform several functions and this web page includes pointers to the different types of products. Different suppliers have product lines that work at various speeds and integrate different functions. They interoperate with each other because they implement the same standards.
• The current SPE speed grades are:
  • 10BASE-T1S: Short-reach 10 Mbit/s, multidrop and point-to-point connections
  • 10BASE-T1L: Long-reach 10 Mbit/s, point-to-point connections
  • 100BASE-T1: 100 Mbit/s, point-to-point
  • 1000BASE-T1: 1000 Mbit/s, point-point

Connectors according to a uniform standard

Connectors are an important connection and disconnection point. The task of the connector is to transmit optical signals and/or electrical power. The external interface is the device interface. Depending on the operating conditions, interfaces are used in protection class IP20 or in M8 / M12 designs for IP6X.
