scope:

This technical report 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 respective IEEE 802.3 single-pair Ethernet (SPE) applications. The channel specifications are referenced from link segment specifications in the following IEEE SPE physical layer specifications: • IEEE 802.3bp, 1 000 Mb/s: 1000BASE-T1 Type A, ≤ 15 m, 1000BASE-T1 Type B, ≤ 40 m; • IEEE 802.3bw, 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 per respective 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, & E3, which are defined per the MICE standard environmental characterization system specified in ISO/IEC 11801-1.
