Anotation

ISO/IEC TR 11801-9906:2025 covers cabling channel specifications, for cabling channels constructed from balanced single-pair cabling components, primarily intended for use in industrial automation and process control applications. The cabling channel specifications are intended to support ISO/IEC/IEEE 8802-3 single-pair Ethernet (SPE) link segment specifications in the following SPE physical layer specifications (PHYs): a) 1000BASE T1 Type B (bp), with reach up to 40 m; b) 1000BASE T1 Type A (bp), with reach up to 15 m; c) 100BASE T1L (dg), with reach up to 500 m; d) 100BASE T1 (bw), with reach up to 15 m; e) 10BASE T1L (cg), with reach up to 1000 m; f) 10BASE T1S (cg), with reach up to 15 m. The channel component specifications are referenced according to corresponding IEC balanced single-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. ISO/IEC TR 11801-9906:2025 cancels and replaces the first edition published in 2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the addition of ISO/IEC/IEEE 8802-3, 100BASE T1L (dg), long reach; b) complete rearrangement of the information contained in Clause 4, Clause 5, Annex A, Annex B, and Annex C.
