ISO/IEC TR 11801-9906:2020

ISO/IEC TR 11801-9906:2020(E) covers channel specifications, for channels constructed from balanced 1 pair cabling components, primarily intended for use in industrial automation and process control applications.<br /> 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:<br /> • ISO/IEC/IEEE 8802-3:2017/AMD4, 1 000 Mb/s: 1000BASE T1 Type A, ≤ 15 m, 1000BASE T1 Type B, ≤ 40 m;<br /> • ISO/IEC/IEEE 8802-3:2017/AMD1, 100 Mb/s: 100BASE T1, ≤ 15 m;<br /> • IEEE 802.3cg, 10 Mb/s: 10BASE T1S, ≤ 15 m; 10BASE T1L, ≤ 1 000 m.<br /> The channel component specifications are referenced according to corresponding IEC balanced 1 pair cable and connector specifications.<br /> Channel specifications include IL, RL, TCL, coupling attenuation, and alien crosstalk parameters specifications.<br /> 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
