Cable Impedance Data: fieldbus_DeviceNet to triax
Characteristic impedance, attenuation at multiple frequencies, capacitance per foot, velocity of propagation, and signal properties for communication and control cables. Covers coaxial (RG58/RG6/RG11/RG213), twisted pair (Cat5e through Cat8), twinax, instrument cable, thermocouple extension, fiber optic (OS2/OM3/OM4), triaxial, and industrial fieldbus cables (Profibus DP, DeviceNet).
