Single Pair Ethernet is a new network technology based on transmission over only two copper wires. As a holistic new physical layer, SPE serves the requirements of the industrial transformation towards ever smaller devices and space-saving infrastructure. SPE enables the simultaneous transmission of data and power even in the smallest field applications. Where previously gateways and translators had to be used to switch to BUS protocols, SPE now connects every sensor and every application directly to higher-level Ethernet networks. If necessary, in real time and with a significantly increased range of functions. Media discontinuity and complex parameterisation of different systems are eliminated with SPE.

As a completely new physical layer, SPE needs its own ecosystem of cables, connectors, semiconductors, passive components and active devices.

SPE SEMICONDUCTORS

The necessary SPE semiconductors such as PHY's and switching chipsets as well as the Power over Data Line (PoDL) controllers, for remote powering of SPE applications, are the heart of SPE devices.

PASSIVE COMPONENTS AND EMV PROTECTION COMPONENTS

Between the PHY and the device interface (Media Dependent Interface = MDI) there are a number of passive components for galvanic isolation, filtering and often also for EMC suppression. These include magnetic components such as transformers and filter chokes, and often also other components for EMC suppression - for example TVS diodes as ESD protection.

SPE CONNECTION TECHNOLOGY
 

The interface to the outside world is the Media Dependent Interface (MDI). Depending on the conditions of use, interfaces with IP20 protection or M8 or M12 designs with IP65/67 protection against water and dirt are used.
 
In addition to the PCB socket, connectors, panel feed-throughs, patch panels, wall sockets, etc. are used depending on the design of the cabling. If the power supply is to be provided via a separate pair of wires, hybrid interfaces in M8 or M12 design are also available.
The T1 interface is equipped with a robust metallic lock made of stainless steel. For a strong connection in industrial environments.

SPE CABLE

SPE DATA CABLES
The core element of the cabling is the SPE data cables for fixed or flexible installation. These are available for different stresses with different sheath materials and also for moving applications for drag chain and torsional stress.

SYSTEM CABLES
Ready-to-use system cables enable fast and error-free cabling and are available with a wide variety of cables and connectors, adapted to the respective application.

Aktive SPE Geräte

ACTIVE NETWORK DEVICES

Managed and unmanaged switches and media converters complete the SPE network infrastructure. As an interface to the standard Ethernet, the switches contain the familiar RJ45 or SFP interfaces. Separate media converters are used to connect SPE networks with other media types such as 2- or 4-pair copper cables, optical cables or wirelessly, for example via WLAN access points.
If the connected devices are also to be supplied via remote power, the switches or media converters must support PoDL or additional PoDL injectors are necessary.

 

WHAT IS THE SPE ECOSYSTEM?

 

SPE Ecosystem 2

 

 

The SPE Ecosystem describes all hardware components necessary for successful Single Pair Ethernet communication, but also standards with information on network design as well as potential application areas in which the technology can be used. The unifying element is the international standard for an industrial SPE mating face - IEC 63171-6/-7 (hybrid SPE + Power).
