Base-T1S enables multidrop Single Pair Ethernet links in aircraft cabins where adjacent unshielded twisted pairs carrying AC power or data signals may be routed in parallel. Crosstalk for identical twist rates under installation-specific geometric variation is evaluated with a computationally efficient modeling methodology based on 2D cable and SPICE simulations, covering 100 Hz to 200 MHz in time and frequency domains. Geometric parameters are swept to assess their influence on crosstalk. For a representative use case worst-case crosstalk is evaluated and model predictions are compared against measurements. The results indicate that the 2D-based workflow is sufficient for the considered aircraft-cabin use case.
