CSA ISO/IEC TR 11801-9906:20

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 E1, E2 and E3, which are defined according to the MICE standard environmental characterization system specified in ISO/IEC 11801-1.
