Whitepaper
Benefits of a Hybrid Connectivity Solution over PoDL
In the whitepaper we will discuss the capabilities of hybrid connectivity solutions compared to existing powering solutions. For many applications power over data lines (PoDL) might be sufficient. However, hybrid connection solutions have a number of advantages for industrial applications.
What you will learn from this whitepaper:
- Powering methods with Single Pair Ethernet (SPE)
- Comparison of network topologies / power distribution structures
- Power transfer with hybrid connectors – discussing M8 interface (standardized in IEC 63171-6) and M12 hybrid interface types (standardized in IEC 63171-7)

APPLICATION NOTES
Single Pair Ethernet – M12 Hybrid System
Hybrid transmission of SPE and power in just one cable and connector is intrinsically important for future IIoT applications. Devices are shrinking, the space for cables and interfaces is decreasing and at the same time the requirements for network connection and power supply are increasing. The hybrid SPE + Power interface M12 hybrid according to IEC 63171-7 is available in seven codings, each serving a specific power level, depending on the application. This makes the interface a useful extension of the functionalities of the M8 hybrid interface defined in IEC 63171-6.

Single Pair Ethernet – Cable standards and construction
Single Pair Ethernet is the technology that perfectly meets the industry's new network technology requirements in the context of Industry 4.0 and IIoT. Central elements of the standard are the Single Pair Ethernet cables. The International Electrotechnical Commission (IEC) has defined and standardized the structure and the high electrical properties in the IEC 61156 series of standards. This application note describes the cable standardization and its design in detail.
