SPE and APL: Focus on Connectivity 4.0

The future of industrial communication is being defined today. Be a part of it and join the discussion in our LinkedIn group!


Single Pair Ethernet (SPE) and Advanced Physical Layer (APL)

Communication and power supply over one line. More power, higher data rates and, with APL, high bandwidths in hazardous areas  — that's what the industrial communication standards of the future promise.

SPE and APL will shape the future of industrial communication. The exact form this will take is currently being discussed and defined in the development departments of automation and connectivity companies. We would like to invite you to help shape the technology and to talk to us about your requirements and our solution offerings. What expectations, hopes and wishes do you associate with a new connectivity standard for the industry? Let us know and join our LinkedIn group "Single Pair Ethernet in Focus". Our experts look forward to exchanging ideas with you. 

We need to talk — about these topics
