Developments are underway to realize an Advanced Physical Layer (APL) for Ethernet
that can be used in process automation and instrumentation to connect field devices
in remote and hazardous locations.
Ethernet-APL is an enhanced physical layer for single-pair Ethernet (SPE) based on 10BASET1L. It will enable long cable lengths and explosion protection via intrinsic safety with communication and power over two wires.
Based on IEEE and IEC standards, Ethernet-APL supports any Ethernet-based automation protocol and will develop into a single, long-term stable technology for the entire process automation community.
