Technical Information
In small-signal applications, noise-free transmission lines are necessary to maintain signal integrity. Simply flexing or twisting a traditional cable can generate voltage spikes with magnitudes in the tens of millivolts. This noise is due to triboelectric charging of the insulator materials, which act as capacitors and store the charge. The addition of conductive low noise layers reduces the noise to the microvolt range.
Low noise layers are typically either a coating or an extruded layer, and sometimes a combination of both.
While preparing a low noise cable for termination, it is important to consider the effect of the outer conductive low noise suppression layer. Isolation of the low noise layer from the conductors is necessary to prevent a short circuit situation. Depending on the type, the low noise layer can either be stripped with conventional mechanical and laser methods (extruded layers), or will require chemical and abrasive stripping methods (coating layers).
