IDG Contributor Network: Reversing course – single-pair Ethernet cabling is the future

For more than 25 years structured cabling systems for voice and data applications have been standardized as 4-pair, balanced UTP, ScTP or Sc/FTP cable that now supports up to 40 Gb/s on 30 meters of category 8. The driving force has been requirements for ever more bandwidth to meet a variety of customer needs.

Suddenly, interest in building automation, “smart” systems and the “Internet of Things” (IoT) is changing the scope of the next generation of cabling systems. Sensors for lighting, HVAC, occupancy, access control and other smart systems require very little bandwidth compared to typical data applications. A sensor transmits just a few bytes of data when polled by a controller or triggered by an external event.
