1 Scope
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 E 1 , E 2 and E 3 , which are defined according to the MICE standard environmental characterization
system specified in ISO/IEC 11801‑1.
