PoE, PoE++, PoDL – Enhancements to IEEE 802.3

Technical Paper Abstract
The IOT is exploding with far reaching applications such as Automotive, Home Automation, Building Automation, and Machine to Machine. Ethernet has become the universal communications network helping to drive this technology.

This paper will look at the current status of the cabling standards such as IEC/SC65C/JWG10, ISO/IECJTC1/SC25/WG3 and ANSI TIA/TR42. In addition, this paper will focus on the status of IEEE 802.3 adaptions of standard Ethernet and the opportunities that it presents to ODVA. IEEE 802.3 committees recently published a higher level PoE (PoE++) and Power over Data link (PoDL). These new powered enhancements can provide an attractive solution for powering a range of small devices up to larger IO devices. PoE++ is attractive for Industrial as it potentially can deliver some 90+ watts to the Powered Device (PD). Even more exciting are the number of newly proposed high speed single pair Ethernet adaptions being defined. These new adaptions will simplify the wiring and reduce space needed for the cabling in industrial installations.

The national and international cabling standards are already actively engaged with IEEE 802.3 working groups helping to define the cabling requirements for these new emerging networks. This paper will discuss the new industrial channel definitions (E2E Links) being defined by ISO/IEC that promise to help our customers successfully install and test their cabling.
