This document covers channel specifications, for channels constructed from balanced 1-pair cabling components, primarily intended for use in industrial automation and process control applications.

This document covers channel specifications, for channels constructed from balanced 1-pair cabling components, primarily intended for use in industrial automation and process control applications.

The channel specifications are consistent with corresponding IEEE 802.3 single-pair Ethernet (SPE) applications and are referenced from link segment specifications in the following IEEE SPE physical layer specifications:

• ISO/IEC/IEEE 8802-3:2017/AMD4, 1 000 Mb/s: 1000BASE-T1 Type A, ≤ 15 m, 1000BASE-T1 Type B, ≤ 40 m;

• ISO/IEC/IEEE 8802-3:2017/AMD1, 100 Mb/s: 100BASE-T1, ≤ 15 m;

• IEEE 802.3cg, 10 Mb/s: 10BASE-T1S, ≤ 15 m; 10BASE-T1L, ≤ 1 000 m.

The channel component specifications are referenced according to corresponding IEC balanced 1-pair cable and connector specifications.

Channel specifications include IL, RL, TCL, coupling attenuation, and alien crosstalk parameters specifications.

Channel EMC related specifications include electromagnetic isolation levels E₁, E₂ and E₃, which are defined according to the MICE standard environmental characterization system specified in ISO/IEC 11801-1.
