Lacing cables together isn't worse than running them parallel using other means e.g. velcro loops unless you're lacing them tight enough to crush the cables.

- ethbr0 4y agoFrom memories of electromag, field coupling from current in parallel cables decays with 2*pi*r, no? So it seems there would be a fair amount of difference at extremely low separation distances. But we never worked through high frequency EE derivations, which I assume are more average-current- or capacitance-dominated in terms of effects?
- SAI_Peregrinus 4y agoThe distance between cables doesn't vary much between lacing methods. The balanced nature of the signals also means the common mode rejection ratio is very high, so external EM interference (which almost entirely shows up as common mode) isn't a huge concern.
